javascript - how to assign function to marionette.template -

as per know, marionette.template take either jquery selector or compiled template string.

if write code in next way, working fine

exports.productinfoview=backbone.marionette.itemview.extend({ dominfo:{ maintemplateid:"tagproductlisttpl", tabletemplateid:"taginfoviewtpl" }, template:commomfunctions.templatecompilation("tagproductlisttpl",""), onrender:function(){ this.templatingproductinformation(); }, modelevents:{ "change:currentjson":"templatingproductinformation" }, templatingproductinformation:function(){ console.log(this.el); //this.el.innerhtml=commomfunctions.templatecompilation(this.ui.maintemplateid,""); } });

note :commonfunctions.templatecompilation() take templateid first argument , data sec argument. compile handlebars template , homecoming compiled template.

if assign homecoming value template, working fine.

i want create info templating,so passing function template in next way.

exports.productinfoview=backbone.marionette.itemview.extend({ dominfo:{ maintemplateid:"tagproductlisttpl", tabletemplateid:"taginfoviewtpl" }, template:function(){ homecoming commomfunctions.templatecompilation("tagproductlisttpl",""); }, onrender:function(){ this.templatingproductinformation(); }, modelevents:{ "change:currentjson":"templatingproductinformation" }, templatingproductinformation:function(){ console.log(this.el); //this.el.innerhtml=commomfunctions.templatecompilation(this.ui.maintemplateid,""); } });

this way working fine, if observer hard coded templateid("tagproductlisttpl") within function.but don't want that. want utilize this.dominfo.maintemplateid instead of hard coding. way it's not working fine.

it's throwing error. know it's out of scope. how can achive this.

can help me.

thanks.

i advise rewrite marionette.templatecache.prototype.compiletemplate responsible template compilation. @ this post, there same issue.

marionette.templatecache.prototype.compiletemplate = function (yourrawtemplate) { // in case if template function if (_.isfunction(yourrawtemplate)) { homecoming yourrawtemplate; } else { homecoming handlebars.compile(yourrawtemplate); } };

and if loading template files remote server need rewrite backbone.marionette.templatecache.prototype.loadtemplate. here example:

marionette.templatecache.prototype.loadtemplate = function ( templateid ) { var template = '', templateurl = 'path_to_your_template/' + templateid + '.html'; // loading template synchronously. backbone.$.ajax( { async : false, url : templateurl, success : function ( templatehtml ) { template = templatehtml; } } ); homecoming template; };
