I have created a checkbox dynamically. I have used addEventListener to call a function on click of the checkbox, which works in Google Chrome and Firefox but doesn't work in Internet Explorer 8. This is my code:
var _checkbox = document.createElement("input"); _checkbox.addEventListener("click", setCheckedValues, false); setCheckedValues is my event handler.
Try:
if (_checkbox.addEventListener) { _checkbox.addEventListener("click", setCheckedValues, false); } else { _checkbox.attachEvent("onclick", setCheckedValues); } Update:: For Internet Explorer versions prior to IE9, attachEvent method should be used to register the specified listener to the EventTarget it is called on, for others addEventListener should be used.
You have to use attachEvent in IE versions prior to IE9. Detect whether addEventListener is defined and use attachEvent if it isn't:
if(_checkbox.addEventListener) _checkbox.addEventListener("click",setCheckedValues,false); else _checkbox.attachEvent("onclick",setCheckedValues); // ^^ -- onclick, not click Note that IE11 will remove attachEvent.

This is also simple crossbrowser solution:
var addEvent = window.attachEvent||window.addEventListener; var event = window.attachEvent ? 'onclick' : 'click'; addEvent(event, function(){ alert('Hello!') }); Instead of 'click' can be any event of course.
addEventListener's third argument is optional anyway, so this can be a good solution, and it's nicer than the if-else branches. But in this case, _checkbox is the target element, not window. :) So maybe you could create a function where the event target is another argument.addEventListener calls - see this topic: stackoverflow.com/questions/1007340/…. So for the window object, it works correctly, but does not work for other nodes inside the document. This way your suggested aliasing is NOT correct for the case mentioned in the original question! What would be your workaround?You can use the below addEvent() function to add events for most things but note that for XMLHttpRequest if (el.attachEvent) will fail in IE8, because it doesn't support XMLHttpRequest.attachEvent() so you have to use XMLHttpRequest.onload = function() {} instead.
function addEvent(el, e, f) { if (el.attachEvent) { return el.attachEvent('on'+e, f); } else { return el.addEventListener(e, f, false); } } var ajax = new XMLHttpRequest(); ajax.onload = function(e) { } IE doesn't support addEventListener until version 9, so you have to use attachEvent, here's an example:
if (!someElement.addEventListener) { _checkbox.attachEvent("onclick", setCheckedValues); } else { _checkbox.addEventListener("click", setCheckedValues, false); } 
Mayb it's easier (and has more performance) if you delegate the event handling to another element, for example your table
$('idOfYourTable').on("click", "input:checkbox", function(){ }); in this way you will have only one event handler, and this will work also for newly added elements. This requires jQuery >= 1.7
Otherwise use delegate()
$('idOfYourTable').delegate("input:checkbox", "click", function(){ }); 
I've opted for a quick Polyfill based on the above answers:
//# Polyfill window.addEventListener = window.addEventListener || function (e, f) { window.attachEvent('on' + e, f); }; //# Standard usage window.addEventListener("message", function(){ /*...*/ }, false); Of course, like the answers above this doesn't ensure that window.attachEvent exists, which may or may not be an issue.
If you use jQuery you can write:
$( _checkbox ).click( function( e ){ /*process event here*/ } ) 
if (document.addEventListener) { document.addEventListener("click", attachEvent, false); } else { document.attachEvent("onclick", attachEvent); } function attachEvent(ev) { var target = ev.target || ev.srcElement; // custom code }
