How to read local file that in located in the same directory as html using javascript -

i have application creates html files containes lot of info draw. files alwayes browsed local file scheme (no http protocol @ all).

i have thought compress info , place in raw format in separate .dat file set in same place .html one.

it not problem read , uncompress .dat file when on web server. don't how read when both files .html , .dat local.

of course of study 1 can utilize browser file objects in case user alwayes asked stupid action chose the file control.

but don't how read when both files .html , .dat local.

i take mean javascript within html file. depending on browser, can't except via file api (which, you've observed, requires have user select file in input[type=file] element).

the way you'd want via ajax (xmlhttprequest), , work in some browsers, not in others. chrome, instance, denies attempts utilize ajax file:// urls (e.g., in pages served file system), local pages, when you're using relative url thefile.dat. ie allows (or @ least, older versions of ie did; haven't tried lately).

so unfortunately, think way can via file api, attendant input[type=file].
