IE6-IE8 Polyfill for missing addEventListener and removeEventListener Javascript methods.
This Polyfill allows a standard way for most browsers to manage event listeners. The lack of standard implementation makes tasks such as executing Javascript after a page is loaded difficult. This Polyfill relies on IE6-IE8's attachEvent and detectEvent which is why it only works for these browsers.
This project origins from :
- https://gist.github.com/2864711/946225eb3822c203e8d6218095d888aac5e1748e (original proposal/idea)
- http://qiita.com/sounisi5011/items/a8fc80e075e4f767b79a#11 (2014 remake)
The second version has not had a lot visibility given it was hosted on a Japanese website. This repository has been setup so that more people can contribute to this Polyfill.
This script is stand alone and does not required any external library.
- Full version: 5k
- Minified: 1.2k
- Minified & Compressed: 0.8k
- Browsers: IE6-IE8 (all other browsers will ignore the script)
- Scope: useCapture is not supported when using the Polyfill
- Limitations: Could potentially not play nice with JQuery and other scripts with similar features.
Simply load this script in your HTML code and use the addEventListener and removeEventListener methods.
Example
- Add the script on your page:
<script src="eventListenerIEPolyfill.js"></script>- Try your new methods on old browsers:
// Example with an object.
var helloWorld = function () {alert('hello world');};
window.addEventListener('load', helloWorld);
// Example passing an argument.
var say = function (something) {alert('You said ' + something);};
window.addEventListener('load', function () {say('hello world')});- You're done.
