Works fine for me. I suspect that there may be some issue with some of your
other code somewhere.
Try opening a new JS file and using:
--- code -->
Object.prototype.getKeys = function(){
var arr = [];
$.each(this, function(k){ if(k!='getKeys') arr.push(k) });
return arr;
}
$(function(){
var x = {a: '1', b: '2', c: '3'};
alert(x.getKeys())
})
<--- code --
It should alert "a,b,c"
Also, I had to edit the function a bit. Because of how the prototype works,
it adds the function name to the list of keys, so you have to filter that
out of there.
