Node.js server is breaking without any error -

i using border module (https://github.com/tjanczuk/edge) read sql database. function follows:

function getbetweenrows(cb) { //console.log("lastcheckedid within function ", lastcheckedid); //console.log("lastinsertid within function ", lastinsertid); console.log("here 2"); var query = { connectionstring: "data source=localhost;initial catalog=db-name;integrated security=true", //source: "select * customermaster customerid between '" + lastcheckedid + "' , '" + lastinsertid + "';" source: "select * customermaster customerid between '2965' , '2972';" }; console.log("query ", query.source); console.log("here 3"); var getrows = edge.func('sql', query); console.log("here 4"); getrows(null, function(error, result) { console.log("here 5"); if (error) { console.log(error); throw error; log.error({rows:error}); } rows = result; log.info({rows:rows}); console.log(rows); console.log("here 6"); cb(rows); }); }

funny thing code working on other systems. on particular system, prints till here 4 , server breaks. doesn't show error whatsoever. how find out what's problem?

sorry, don't know posted happening diferently on diferent systems if want debug , find step step diferences on 2 systems, utilize node debugger:

http://nodejs.org/api/debugger.html

it's worth getting know.

also, have noticed occasional issues cannot yet explain, when throwing errors. seek commenting out throw line on offending scheme (an maybe log.js phone call well.) if fixes issue, know errors.

let me know find.

c++ - Would std::count_if be faster without an if? -

here's gcc std::count_if code

template<typename _inputiterator, typename _predicate> typename iterator_traits<_inputiterator>::difference_type count_if(_inputiterator __first, _inputiterator __last, _predicate __pred) { [snip] typename iterator_traits<_inputiterator>::difference_type __n = 0; (; __first != __last; ++__first) if (__pred(*__first)) ++__n; homecoming __n; }

my question: work improve (i.e., faster) use

__n += __pred(*__first); // instead of if statement

this version add, doesn't branch.

the replacement gave is not equivalent, because there far fewer restrictions on predicate think:

anything can used in conditional context (can contextually converted bool), valid return-type predicate (an explicit conversion bool enough). that return-type can react funny beingness added iterators difference-type. 25 algorithms library [algorithms] 25.1 general [algorithms.general]

8 predicate parameter used whenever algorithm expects function object (20.9) that, when applied result of dereferencing corresponding iterator, returns value testable true. in other words, if algorithm takes predicate pred argument , first iterator argument, should work correctly in build pred(*first) contextually converted bool (clause 4). function object pred shall not apply non-constant function through dereferenced iterator.

the homecoming giving replacement indigestion standard integer-type, , value neither 0 nor 1.

also, maintain in mind compilers can optimize nowadays (and c++ ones need to, template-stuff layered deep).

performance - JMS queue consumer: synchronous receive() or single-threaded onMessage() -

i need consume q, , stamp sequence key on each message indicate ordering. i.e. consumption needs sequential. performance/throughput point of view, improve off using blocking receive() method, or async listener single-threaded configuration on onmessage() method?

thanks.

there many aspects impact performance , throughput; in pure jms terms it's not possible state sync or async model of getting messages less or more efficient. depend on big number of factors how application written, other resources it's using, implementation of chosen messaging provider , other factors such machine performance , configuration of both client , server machines.

this discussion, single vs multi-threaded jms producer, covered of these topics.

to sequence, if single threaded, single session jms specification gives assurances on message ordering; best review spec see if matches overall requirements.

often people insert application sequence number @ message production time; consumer can hence check getting right message in order. adding sequence number @ consumption time won't help consumer.

keep in mind stricter requirement messaging ordering more restrictive overall architecture gets , harder implement horizontal scalabilty.

i know there has been few topics similar one, don't inquire same question , answers not need. seek explain briefly situation.

i have 2 keyboards, 1 standard usb keyboard (hid), other gpio keyboard. there keys commonly reported both keyboards need take different actions in qt application depending on keyboard key pressed.

at moment both keyboards work fine @ same time, can't find way identify keyboard comes pressed key.

is possible? i'm, using qt 4.8.5 , can recompile in case needed accomplish need.

any help, hint, tip highly appreciated.

thank help,

william

qt not have feature observe keyboard pressed. should utilize linux event interface distinguish between 2 inputs. when input available 1 of hardwares, can access reading character devices under /dev/input/ directory. instance have file /dev/input/by-id/usb-0b38_0010-event-kbd read see input specific keyboard.

you can read specific files 2 keyboards in 2 separate threads , each time read new info 1 of them, send signal main thread notify input of keyboards :

in first thread :

qfile file("/dev/input/by-id/fileforkeyboard1"); if(file.open( qiodevice::readonly | qiodevice::text ) ) { qtextstream stream( &file ); while(true) { stream.read(1); emit keyboard1_pressed(); } }

in sec thread :

qfile file("/dev/input/by-id/fileforkeyboard2"); if(file.open( qiodevice::readonly | qiodevice::text ) ) { qtextstream stream( &file ); while(true) { stream.read(1); emit keyboard2_pressed(); } }

note should have root access read these files.

sql - Arithmetic overflow error converting datetime's -

i have table stores date info in nvarchar in format of (dd/mm/yyyy),when convert column datetime using convert(nvarchar(100), dt, 101) doesn’t have issue ,however when want select top x rows ,i got next error:

msg 8115, level 16, state 2,arithmetic overflow error converting look info type datetime.

the next sample of code:

declare @d nvarchar(100); set @d='20/11/2012' select top 1 @d, (select date_diff = datediff( day, cast(convert(nvarchar(100), @d, 101) datetime), '2014-10-01 00:00:00')) d

it's sql interpreting first date time 11th day of 20th month in year 2012.

try in 1 of sql's preferred date formats.

my preferred format dd-mmm-yyyy because never ambiguous:

declare @d nvarchar(100); set @d='20-nov-2012' select top 1 @d, (select date_diff = datediff( day, cast(convert(nvarchar(100), @d, 101) datetime), '01-oct-2014 00:00:00')) d

sql picks date format based on language.

you can explicit , tell utilize dmy format in query so:

set dateformat 'dmy'

based on comments below inferring sort of query:

--pretending table in database varchar dates :( create table #test (dt varchar(100)) insert #test values ('20/11/2012') set dateformat 'dmy' --works --set dateformat 'mdy' --doesn't work select top 1 dt, (select date_diff = datediff( day, cast(convert(nvarchar(100), dt, 101) datetime), '2014-10-01 00:00:00')) d #test drop table #test

but in case selecting varchar date table, setting date format correct's issue. seek testing differing dateformats.

i create 1 single temp folder, , generate random file names (md5, guid, don't matter). same script generate file on folder visualization, before generation itself, should check files on folder, excluding files generated >= 1 day ago. check filemtime function , this question if have doubts how file creation/modification date.

c# - multithreaded unit test - notify calling thread of event to stop sleeping -

c# - multithreaded unit test - notify calling thread of event to stop sleeping -

i wrote test (nunit) test amazon ses email sending functionality should generate bounce notification in amazon sqs queue. poll queue in loop 1 min on new thread wait , verify bounce notification.

i'd increment time few minutes ensure dont miss it. response may come within seconds in case i'd want record how long took , finish test there no point go on waiting 1 time receipt verified.

how can accomplish threading scenario in clean way, , mean without polluting methodinmainapp() test code. in main app should not happen (it should go on polling indefinitely), should stop in test. should pass in threadstart function both entry points doesnt reply question im asking.

[test] public async void sendandlogbounceemailnotification() { thread bouncesthread = startup.methodinmainapp(); bouncesthread.start(); bool success = await _emailservice.sendasync(...); assert.areequal(success, true); //sleep thread 1 min while //bouncesthread polls bounce notifications thread.sleep(60000); } public static thread methodinmainapp() { ... thread bouncesthread = new thread(() => { while (true) { receivemessageresponse receivemessageresponse = sqsbouncesclient.receivemessage(bouncesqueuerequest); if(receivemessageresponse.messages.count > 0) { processqueuedbounce(receivemessageresponse); //done test } } }); bouncesthread.setapartmentstate(apartmentstate.sta); homecoming bouncesthread; }

use monitor class.

instead of thread.sleep(60000), utilize this:

lock (_lockobject) { monitor.wait(_lockobject, 60000); }

then want signal thread continue:

lock (_lockobject) { monitor.pulse(_lockobject); }

of course of study requires adding static readonly object _lockobject = new object() somewhere in class.

i'm not saying overall strategy right approach. seems here, improve unit test method explicitly phone call other method doing work wait , validate response. above should address specific question.

How to handle NotificationBar in android -

How to handle NotificationBar in android -

i tried code form reply of question: how set media controller button on notification bar?

by calling

shownotification()

method app gets closed. how prevent this? , how can handle method called if mobile phone api >= 16. because think available since api 16.

i've read, there solution lower api:

import android.support.v4.app.notificationcompat;

but didn't got working, wanted prevent calling it.

and can delete notification bar, ondestroy() of app?

the code on page hard case using remoteviews, , looks dubious anyway. (e.g. creates subclass of notification constructor creates notification.)

the normal approach utilize notificationcompat.builder build notification, , notificationmanager or notificationmanagercompat show , cancel it. see notifications api guide details , illustration code.

also see notifying user documentation , notifications design guide.

generally, app should show notification when activity not visible. when user taps on notification, should open activity should in turn cancel notification.

matlab - Unconstrained nonlinear optimization function -

i want optimize unconstrained multivariable problem using fminunc function in matlab. here example:

minimize function f(w)=x'ax

create file myfun.m:

function f = myfun(x) f = x'*a*x + b'x

then phone call fminunc find minimum of myfun near x0:

[x,fval] = fminunc(@myfun,x0).

my problem in algorithm, matrix a , vector b in myfun.m not fixed, can changed on loops, cannot type them hand. how can pass values a , b?

there few options passing additional arguments objective function. simple 1 yours, create anonymous function, save values of a , b when created:

a = mymata(); b = myvecb(); myfun = @(x) x.'*a*x + b.'*x; [x,fval] = fminunc(myfun,x0); % utilize no @ anonymous function

the other 2 options global variables (yuck!) , nested functions. nested function version looks this:

function [x,fval] = myopt(a,b,x0) [x,fval] = fminunc(@myfunnested,x0); function y = myfunnested(x) y = x.'*a*x + b.'*x; end end

but think not utilize fminunc solve minimization of x'ax + b'x...

do need alter "mydomain" in line two? not want sites have access. internal firefox extension.

i have read several guides here , here mozilla.

here code have far. clipboard contents should sent post method via xmlhttprequest. xmlhttprequest works, have been using other variables.

var pastetext = document.execcommand('paste'); var req = new xmlhttprequest(); req.open('post', pastetext, true); req.onreadystatechange = function(aevt) { if (req.readystate == 4) { if (req.status == 200) dump(req.responsetext); else dump("error loading page\n"); } }; req.send(null);

i grateful help. give thanks you

what need not execcommand need read info clipboard. addon in privelaged scope don't need worry preferences. (user.js firefox-addon right?)

see here:

this way can read contents var pastedcontents.

ios - Custom UIView drawing with layoutSubviews vs drawRect -

ios - Custom UIView drawing with layoutSubviews vs drawRect -

should drawing of cashapelayers called drawrect() or layoutsubviews()?

according apple's documentation on uiviews, drawing operations should placed in drawrect().

however not case in kevin cathey's wwdc session: what's new in interface builder (where demonstrates process of building custom uiview accessible in interface builder).

during demonstration performs drawing of view in layoutsubviews, rather drawrect.

his explanation that:

if implement drawrect, that's not going best performance; whereas, using sublayers , subviews going performance.

from i've read far on stackoverflow, seems overriding drawrect() method can cause reduced performance. partially due setneedsdisplay triggering manual redraws beingness expensive.

but looking through apple documentation , real world applications. makes sense drawrect() should responsible drawing of view, , layoutsubviews() handling positioning.

i depends. if size of shape going dependent on auto layout scheme might beneficial drawing in layout subview versus draw rect.

first, why layout subviews ever have improve performance? have uiview (my parent view) drawing circle view (my subview) using shape layer. size of circle determined width , height constraint in parent view. ever need redraw circle when either width/height constraints changed on parent view. instance beneficial have drawing code in layout subviews because ever need redraw shape layer when constraints change. let's see auto layout cycle

update constraints layout subviews render views

by time layout subviews called know size of frame working , can safely perform our drawing. know documentation says should utilize method set frame, bounds, etc. however, drawing within frame doesn't sound unreasonable depending on circumstances.

if circle view isn't dependent upon auto layout scheme , changed @ anytime regardless of layout of ui, more beneficial have drawing in draw rect can updated. think less ideal situation more ui's in ios conform using auto layout, hence recommendation of using layout subviews.

i want create view hierarchy programmatically using auto layout hierarchy has next structure: uiview -> uiwebview want leave space uitoolbar @ bottom of uiview.

the result should in xib file:

code far:

when trace using:

po [[uiwindow keywindow] _autolayouttrace]

i both uiview , uiwebview have ambiguous layout.

what problem approach?

you shouldn't set translatesautoresizingmaskintoconstraints no controller's self.view. if remove line, constraints have should adequate. btw, there's no need zeros in format string (although don't wound either),

this "h:|[webview]|" equivalent "h:|-0-[webview]-0-|".

this loop written excel takes ranges of 2 unique lists , searches them in table on different sheet. 2 column search, 2 values list must appear in row accumulator count. works fine when parse lots of info can waiting minutes on end. looking way create loop much faster. help appreciated. in advance.

as tip, seek create variable with

range("formattingtable[" & findtablecolumn & "]")

value , avoid within loop. or improve replace:

worksheets("formatting").range("formattingtable[" & findtablecolumn & "]")

by range value within loop.

who caused problem, app or database? or net?

reason:

at point clear tcp connection sitting idle broken, our app still assumed open. idle connections, mean connections in pool aren’t in active utilize @ moment application.

after search, came conclusion network firewall between app , database dropping idle/stale connections after 1 hour. seemed mutual problem many people have faced.

solution:

in grails, can set in datasource.groovy.

environments { development { datasource { //configure dbcp properties { maxactive = 50 maxidle = 25 minidle = 1 initialsize = 1 minevictableidletimemillis = 60000 timebetweenevictionrunsmillis = 60000 numtestsperevictionrun = 3 maxwait = 10000 testonborrow = true testwhileidle = true testonreturn = false validationquery = "select 1" } } } }

java - Localizing numeric values in excel -

java - Localizing numeric values in excel -

bigdecimal mynumber = new bigdecimal(1234.56); numberformat instance = numberformat.getinstance(locale.german); string localizednumber = instance.format(mynumber); system.out.print("\nformatting " + localizednumber); o/p ->1.234,56

till here code works fine below line gives numberformatter exception given string contains comma in it.

bigdecimal bigdecimal = new bigdecimal(localizednumber);

i want numeric values localized cannot homecoming string putting number string shows below error in excel number in cell formatter text or preceded apostrophe

is there way can homecoming numeric value(bigdecimal / integer / biginteger etc) in localized format won't above error in excel , can perform filter operations on excel data.

i've tried new bigdecimaltype().valuetostring(value, locale); , new bigdecimaltype().stringtovalue(s, locale); of dynamic jasper reports api.

happy reply question asked me , quite surprised no 1 replied this. don't have number localization in excel export because it's done our operating scheme settings automatically.

go "region , language" -> format -> select language/country name -> apply , check excel before generated in english.

you see numbers in selected country's number format. :)

my application mvc5 c#, trying execute following:

@{ var s = model.physicalexam; if (s == null) { <script> alert("1"); $("#newsale1").hide(); </script> } else { <script> alert("2"); $("#newsale1").show(); </script> } }

alert works, not hide or show button. appreciate suggestions.

i guess newsale1 maybe isn't loaded in dom when script code executed. should set blocks within document ready event.

can help me, please? great.

it's fixed. please re-build.

root cause:

intel xdk not back upwards library project, newly introduced in plugin (com.google.playservices@21.0.0).

<framework src="libs/google-play-services_lib" custom="true" />

you may ask, why alter of "com.google.playservices" cause admob plugin fail?

the admob plugin dependent on plugin named "com.google.playservices", adds google play services jar project.

the "com.google.playservices@19.0.0" simple jar file, worked quite well.

<source-file src="google-play-services.jar" target-dir="libs" />

but "com.google.playservices@21.0.0" using new feature include whole library project.

<framework src="libs/google-play-services_lib" custom="true" />

it works quite if build locally cordova cli, fail when build intel xdk.

to maintain compatible intel xdk, dependency of admob plugin changed "com.google.playservices@19.0.0", simple jar file.

now works intel xdk again.

windows - Any way to see where python is importing a module from? -

windows - Any way to see where python is importing a module from? -

so installed facebook module, realized wrong one, used pip uninstall , installed facebook-sdk. here code:

import facebook token = '[token]' graph = facebook.graphapi(token) profile = graph.get_object("me") friends = graph.get_connections("me", "friends") friend_list = [friend['name'] friend in friends['data']] print friend_list

and

traceback (most recent phone call last): file "c:\users\mgraves\desktop\facebook.py", line 1, in <module> import facebook file "c:\users\mgraves\desktop\facebook.py", line 5, in <module> graph = facebook.graphapi(token) attributeerror: 'module' object has no attribute 'graphapi'

when looking up, every result says uninstall facebook , facebook-sdk , reinstall facebook-sdk. , have, many many times. searched /python27/ facebook afterwards create sure files gone.

is there way on windows machine trace importing "facebook" from?

module objects have __file__ attribute, , object representation includes file:

print facebook print facebook.__file__

in case, importing your own script; named facebook , masking installed module:

file "c:\users\mgraves\desktop\facebook.py", line 1, in <module> import facebook file "c:\users\mgraves\desktop\facebook.py", line 5, in <module> graph = facebook.graphapi(token)

note filename in first line, fact same file used import. python stores main script __main__, importing script results in module beingness created actual filename.

parallel processing - MPI Parallelization time consumption -

parallel processing - MPI Parallelization time consumption -

i have 2 blocks of code consume 2 seconds each, in classic construction run sequentially, in 4 seconds

in mpi format, supposed consume 2 seconds takes 5 seconds

why?

int main ( int argc, char *argv[] ) { mpi_init( &argc, &argv ); mpi_comm_size(mpi_comm_world,&p ); mpi_comm_rank(mpi_comm_world,&id); if(id==0) { // 2 seconds block } if(id==1) { // 2 seconds block } mpi_finalize(); }

what take 5 seconds? if have measured time whole program, problem mpi_init() , mpi_finalize() time consuming. in order see speedup increment "blocks".

MySQL select to find similar lat/lng with matching name column -

MySQL select to find similar lat/lng with matching name column -

i trying find rows in single table of locations have same latitude/longitude when rounded 2 decimal places same name. here table (for example):

+---------------------------------------+ | id | lat | lng | name | +---------------------------------------+ | 11 | -11.119 | 13.891 | smith's place | | 81 | -11.121 | 13.893 | smith's place | +---------------------------------------+

what select statement find instances (like 1 above) lat/lng match when rounded 2 decimal places...and names same?

i looking similar query doesn't work (but asking after):

select * pb_locations grouping round(lat,2),round(lng,2) name = name having count(id) > 1

where name = name true, since it's comparing within same row, not across different rows.

you need set 3 columns in group by clause.

select * pb_locations grouping round(lat, 2), round(lng, 2), name having count(*) > 1

mysql - mysqli connect function in PHP -

mysql - mysqli connect function in PHP -

i've started mysqli. when create mysqli connection database having problem function.

my code :

$link=mysqli_connect("host", "user","password","database_name", true) or die ('i cannot connect database because: ' . mysqli_connect_error()); $query="call `database_name`.`table_name`('107','0100000000',63,122)"; $result=mysqli_query($link,$query); $rs = mysqli_fetch_array($result); $image = $rs['image']; $title = $rs['title']; echo $title; mysqli_close($link);

when execute in php code throws error.

error :

can't connect mysql server on 'host_name' (110)

but when utilize mysql extension works fine.please guide me doing mistake.

thanks

the 5th argument in mysqli_connect() port number.

true evaluates 1 , that's not right port. remove argument not required - default used.

in mysql_connect() 5th argument 'new link', true appropriate.

as migrating mysqli, might want read this answer gives basic changes old mysql extension.

by way, using syntax declaring new connection, thought might want know can have more 1 connection when using mysqli. have set new variable, ie;

$link1 = new mysqli($host,$username,$password,$database); $link2 = new mysqli($host2,$username2,$password2,$database2);

then can take connection utilize when executing queries etc. example;

procedural:

$result1 = mysqli_query($link1,$sql);

oo:

$result2 = $link2->query($sql);

Lambda calculus entire expression substitution -

Lambda calculus entire expression substitution -

about substitution of free occurances: can have substitution of entire expression(function, application), or of variable:

example:

current look \x.\y.(y, z) expression replaced: \y.(y z) p have \x.p.

is possible?

yes, possible. 1 way consider substitution of occurrences. occurrence string on set {1,2,3}, , every lambda-term m, sub-expression m/u @ occurrence u defined as:

m/[] = m m/0u = n/u, if m=\x. n m/1u = p/u, if m=pq m/2u = q/u, if m=pq

(i utilize symbol [] denote empty string.)

now define substitution m[u := n] term obtained replacing occurrence u n in m. i've seen kind of substitution in of p.-l. curien work.

Unexpected behavior from Python -

Unexpected behavior from Python -

i'm new python , bit confused way python treats empty object.

consider code piece;

a = {} if a: print "a alive!" else: print "a not alive!" if not a: print "not a!" else: print "a!" if none: print "a none!" else: print "a not none!"

i next output code piece.

a not alive! not a! not none! edit::

i under assumption object initialized {} valid object. why doesn't python treat way? , why diff output diff if conditions?

edit 2::

in c++, when say

object obj; if (obj){ }

it come in if block if obj not null(regardless if garbage value or whatever)

but same thing when translate python.

a = {} #this valid object if a: # doesn't work!

why? , read python evaluates {} false. why that?

i see nil weird in output. let's go step-by-step:

a dictionary, more dictionary object; a dictionary, it's empty, truth value false

therefore:

the first if, since a false, prints else statement , that's right; the sec if, since not a evaluates true because a false, prints if part , that's right too. last, not to the lowest degree a not none object, dict object, it's right else part taken , printed.

[[uibutton appearancewhencontainedin:[eabaseviewcontroller class], nil]setbackgroundimage:[uiimage imagenamed:@"gradient_border"] forstate:uicontrolstatenormal]; [[uibutton appearancewhencontainedin:[eabaseviewcontroller class], nil]setbackgroundimage:[uiimage imagenamed:@"gradient_border_grey"] forstate:uicontrolstatehighlighted]; [[uibutton appearancewhencontainedin:[eabaseviewcontroller class], nil]setbackgroundimage:[uiimage imagenamed:@"gradient_border_grey"] forstate:uicontrolstateselected]; [[uibutton appearancewhencontainedin:[eabaseviewcontroller class], nil]setbackgroundimage:[uiimage imagenamed:@"gradient_border_grey"] forstate:uicontrolstateselected|uicontrolstatehighlighted]; [[uibutton appearancewhencontainedin:[eabaseviewcontroller class], nil]setbackgroundimage:[uiimage imagenamed:@"grey_border_grey"] forstate:uicontrolstatedisabled];

the problem is, when click button, instead of changing image gradient_border_grey changes alpha instead. cannot find how prepare it?

how prepare ?

i needed set button type custom prepare problem

c - invalid operands to binary * (have ‘int’ and ‘int *’) -

c - invalid operands to binary * (have ‘int’ and ‘int *’) -

i trying find out factorial of number using recursion , passing pointers function arguments. error appears time. debugers , coders! need assistance this.

the code #include<stdio.h> int *factorial(int *); int value, p=0, q=1, x, tmp; void main() { int *result; puts("enter value::"); scanf("%d",&value); result = factorial(&value); printf("\nthe result is::%d\n", *result); } int *factorial(int *n) { if(*n == p || *n == q) { return(&q); } else { tmp = *n -1; *n *= (factorial(&tmp)); return(n); } } error: error: invalid operands binary * (have ‘int’ , ‘int *’) *n *= (factorial(&tmp));

this line :

*n *= (factorial(&tmp));

should be

*n *= *(factorial(&tmp));

however, careful implementation because recursive, uses pointers globals.

would standard implementation not work you?

int factorial(int n) { if(n==0) homecoming 1; else homecoming factorial(n-1)*n; }

with standard, need prompt user non-negative values only.

c pointers recursion factorial

php - Whats wrong in regular expression -

php - Whats wrong in regular expression -

whats wrong with:

$pattern = '/9[0-5[7-9]]{1}[\\d]{10})|([0-2]\\d{11}/'; $subject = '971093342689';

trying check in php

preg_match($pattern, $subject)

receive error:

preg_match(): compilation failed: unmatched parentheses @ offset 22

the 2 parentheses not closed:

$pattern = '/9[0-5[7-9]]{1}[\\d]{10})|([0-2]\\d{11}/'; ^^^^

if sign need, have escape it. otherwise need open , closed parentheses in regexp.

javascript - Mixitup.js and multiple filtering -

javascript - Mixitup.js and multiple filtering -

i've taken code http://codepen.io/patrickkunka/pen/iwcap , modified it, can't create work desired.

if select 1 filter, works fine - if start compare filters, it's not returning right result.

i'm returning "filters" dynamicly - shouldn't problem.

can give me heads on this?

self.$filters.find('.filterboxes').each(function () { self.groups.push({ $inputs: $(this).find('input'), active: [], tracker: false }); });

changed to

> self.$filters.find('.filters').each(function () { > self.groups.push({ > $inputs: $(this).find('input'), > active: [], > tracker: false > }); > });

and added css class "filters" on each of groups

<div id="filters"> <div id="gendersfilter" class="filters"></div> ... </div>
