How to fix Array indexOf() in JavaScript for IE browsers
Raw
array_index_of.js
/*
If you have worked with JavaScript at any length you are aware that IE does not implement
the ECMAScript function for Array.prototype.indexOf() [including IE8]. Not a huge problem
because you can extend the functionality on your page with the following code.
*/
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(obj, start) {
for (var i = (start || 0), j = this.length; i < j; i++) {
if (this[i] === obj) { return i; }
}
return -1;
}
}
