Silly example:
<script>
var a = {
'b' : {
'c' : "success!!"
}
};
var d = 'b.c';
</script>
How could I access success!! if I can't go for the obvious solution a.b.c or a['b']['c'], but instead have to use d? I tried a[d], which doesn't seem to do the trick. I also tried to fiddle with eval(). Is this even possible?
If it's really necessary to have the keys in a string separated with a dot, I would use split and reduce:
var success = d.split(".").reduce(function (obj, key) {
return obj[key];
}, a);
