addEventListener not working in IE8

Question

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 <

Answer 1

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.
