Firstly - my description ;)

I've got a XmlHttpRequests JSON response from the server.
MySQL driver outputs all data as string and PHP returns it as it is, so any integer is returned as string, therefore:

Is there any fast alternative (hack) for parseInt() function in JS which can parse pure numeric string, e.g.

var foo = {bar: 123};

...

foo.bar = parseInt(foo.bar); // (int) 123
