Probably an async issue - any code after the $.getJSON call (but not in the callback) will get executed before the async call returns. Any code that is dependent on this.Settings being set with the returned data must be within the callback function.
Also "this" is probably not what you are expecting it to be. Do an alert or console.log with "this" in your callback function to make sure it's what you're expecting. -- Josh -----Original Message----- From: jquery-en@googlegroups.com [mailto:jquery...@googlegroups.com] On Behalf Of Ido Yehieli Sent: Monday, January 04, 2010 9:55 AM To: jQuery (English) Subject: [jQuery] Callback in $.getJSON is called but variable assignment doesn't persist. Hi, on the following code: $.getJSON("http://www.tametick.com/test2/json/settings.json",function (data) { this.Settings = data; alert(data); alert(this.Settings); }); which can be found on http://www.tametick.com/test2 (line 63 in http://www.tametick.com/test2/js/cardinal-quest.js), I am getting the alerts correctly (returning the object read from the file) but after the function ends this.Settings revurts back to null and I get the error: Error: Settings is undefined Source File: http://www.tametick.com/test2/js/cardinal-quest.js Line: 70 Any idea what is going wrong? Thanks, Ido.
