Simple jQuery code snippet to return the keys of an object. Could be useful when you want to create dynamic variables from the keys of the object and reference the values directly.

$.extend({
    keys:    function(obj){
        var a = [];
        $.each(obj, function(k){ a.push(k) });
        return a;
    }
})

// Usage:
var obj = {a: 1, b: 2, c: 3, d: 4, jquery: 'noob'}
alert($.keys(obj));    // a,b,c,d,jquery
