Question

I get this response from an Ajax request.
Javascript seems to intepret it as a string.
(When I say alert this.responseText, the whole string is shown)

How can i convert it to a javascript object (JSON)?

{"response": {
   "success": "The activity has been removed",
   "message": "0"

  }
}

I am not using jquery.

It’s not the safest thing in the world, but you can do this:

var value = null, txt = this.responseText;
eval("value = (" + txt + ")");

It might be a little safer to do:

var value = null, txt = this.responseText;
!function(window) { eval("value = (" + txt + ")"); }();

but there are still all sorts of potential hacks. You’re better off using a library.
