in particular case, aren't making ajax call @ all, instead you're making jsonp request. luckily, these incredibly easy replicate , work in browsers.

var s = document.createelement("script"),     callback = "jsonpcallback_" + new date().gettime(),     url = "http://forexplay.net/ajax/quotes.php?callback=" + callback; window[callback] = function (data) {     // worked!     console.log(data); }; s.src = url; document.body.appendchild(s);
