Haha, no worries Mike. I didn't actually test out the solution till later,
and it wasn't until later still that the fact other Objects would have to
filter it occurred to me. S'what I get for doing lunch break snippets. :P
Anyway, I have updated the function to no longer use the Object.prototype
method, but to add it as a jQuery utility.
$.extend({
keys: function(obj){
var a = [];
$.each(obj, function(k){ a.push(k) });
return a;
}
})
// Useage:
var obj = {a: 1, b: 2, c: 3, d: 4, kitty: 'cat'}
alert($.keys(obj)); // a,b,c,d,kitty
