DBJDBJ / cross_browser_cross_javascript_string_trim.js
Created March 11, 2010 14:40
Use native String.prototype.trim function wherever possible. Do not use String.trim. It is not part of ES5. Browsers are not required to implement it.
// dbjdbj@gmail.com
// Inspired also by http://github.com/dieseltravis
(function () {
var trimLeft = /^\s+/, trimRight = /\s+$/;
// Verify that \s matches non-breaking spaces (IE fails on this test)
if ( !/\s/.test( "\xA0" ) ) {
trimLeft = /^[\s\xA0]+/;
trimRight = /[\s\xA0]+$/;
}
// Use native String.prototype.trim function wherever possible

My 2009 R+D on DOM page changes and "Mutation Events". Tested on Chrome only. And perhaps in IE too ;)
