internet explorer 8 - Is the javascript .map() function supported in IE8?

Question

When doing this:

var a = new Array("a", "b");
a.map(function() { });

in IE8 I get:

"Object doesn't support this property or method"

Is this method not supported in IE8, or do I have some other problem? I've had a Google, but get lots of Google Maps javascript issues/questions...

Edit: OK so IE8 and below DO NOT support the .map() function. Copy-paste the code from MDN here which will add the .map() function to the Array prototype exactly per the specs if not natively supported (and it seems to work perfectly).

Answer 1

The solution is jQuery.map

Instead of this: a.map(function( ) { });

You have to do

jQuery.map(a, function( ) { //what ever you want todo .. }
