how to use ajax request in jsFiddle
It's not possible to make an AJAX request to a domain other than the current one, as it's a pretty basic security risk.
jsFiddle have an API for testing AJAX requests which you should use instead.
Here's a working fiddle of what you are probably looking for.
I used http://echo.jsontest.com but you can substitute for your valid URL.
var echo = function(dataPass) { $.ajax({ type: "POST", url: "/echo/json/", data: dataPass, cache: false, success: function(json){ alert("UID=" + json.uid + "\nName=" + json.value); } });};$('.list').live('click', function(){ $.get("http://echo.jsontest.com/uid/12345/value/nuno_bettencourt", function(data) { var json = { json: JSON.stringify(data), delay: 1 }; echo(json);; }); });
