javascript - Functions in Namespace Not Attaching Event Listeners to HTML Elements -

-

i have local page in html , javascript helps me basic tasks @ work. i've been going on code , rewriting use best practices, since helps me learn, , i've been trying study namespacing , put use rewriting common page functions , event listeners.

window.onload = (function() { var automationpagewrapper = (function() {     var self = {}      self.evntlisteners = {         btntextchange: function() {             // code changes button text when clicked             },         btncolorchange: function(formid) {             //  code iterates through buttons name             //  , makes them same default color             }          }      self.listeners = {          btnlisteners: function() {              //  add event listeners having buttons here              }          }     return self;     }); automationpagewrapper.listeners.btnlisteners(); });
  1. why isn't attaching event listeners?
  2. is there better way formatting/calling this?
  3. is professional method setting javascript code?

i tested event listeners taking functions , posting them chrome console, think work.

the full text, since people reading through of it:

  //  global namespace page functions window.addeventlistener("onload", function() { var automationpagewrapper = (function() { var self = {};   //  namespace event listeners     self.evtlisteners = {           //  function change color of selected button             btncolorchange: function(formname) {                 var elementsbyname = document.getelementsbyname(formname);                  (var = 0; < elementsbyname.length; i++) {                         if (elementsbyname[i].classname == "active") {                               elementsbyname[i].classname = "inactive";                                 break;                             }                     }              },             //  add event listeners         listeners: {                  btnlisteners: (function () {                     document.getelementbyid('sidebar').addeventlistener("click", function(e){                             self.evtlisteners.btncolorchange('sidebuttons');                             e.target.classname = "active";                         });                     })()              }  }  return self; })();  automationpagewrapper.listeners.btncolorchange(); });

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.. /...
