Using Javascript In Dynamically Embeded HTML? -

-

how use, or correctly use, javascript in dynamically embedded pages/content?

when event occurrs loading php/html page html element. javascript works fine on outter page, or page content gets loaded into, not work on page being loaded.

here request function: 

function sendservicerequest(file, nvpsenddata, successcallback, failcallback) {     $.ajax({         type: "post",         url: file,         data: nvpsenddata,         datatype: 'html'     }).success(function(data, status) {         console.log(".done");         console.log("return ajax status: " + status);         //console.log("success data: " + json.stringify(data));         successcallback(data, status);     }).fail(function(data, status, error) {         console.log(".fail");         console.log("return ajax status: " + status);         //console.log("return data: " + json.stringify(data));         failcallback(data, status, error);     }); }

then have php page, viewscripts.php, has javascript file included, handles loading process

view_events.js

document.addeventlistener('domcontentloaded', function() {     var rx = document.queryselector("#rx-number").value;     sendservicerequest(         "/comments/get_content.php",         {action:"loadcontent", loadtype:"comments", rx_number:rx},         function(data, status) {             document.queryselector("#rx-comments-container").innerhtml = data;         },         function(data, status, error) {             console.log("ajax send service request failed while loading comments!");         }     ); });

then in code above, /comments/get_content.php verifies data being sent, , loads page comment.php div element, #rx-comments-container. until point fine. it's javascript in comment.php not want work. have tried including '.js' file specified functions handle events comment.php, not work. have tried including event functions in view_events.js, listed above, included in viewscripts.php, , not want work either. have tried embedding javascript directly comments.php, doesn't work either.

here javascript included in comments.php: 

document.addeventlistener('domcontentloaded', function() {     document.getelementsbyclassname("edit-rx-comment-glyph").addeventlistener("click", function () {         var id = this.value;         sendservicerequest(             "/comments/get_content.php",             {action: "loadcontent", loadtype: "editcomment", comment_id: id},             function (data, status) {                 document.queryselector('#' + id).innerhtml = data;             },             function (data, status, error) {                 console.log("ajax send service request failed while loading edit form!");             }         );     });      document.getelementsbyclassname("comment-history-glyph").addeventlistener("click", function () {         var id = this.value;         sendservicerequest(             "/comments/get_content.php",             {action: "loadcontent", loadtype: "viewhistory", comment_id: id},             function (data, status) {                 document.queryselector('#comments-body').innerhtml = data;             },             function (data, status, error) {                 console.log("ajax send service request failed while loading edit form!");             }         );     }); });

i managed figure out. guess doing wrong, because code ended working. used onclick event sendservicerequest function, , ended working. didn't need include other js files.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
