getJSON break FF history

[monstroplante]

If i redirect on the callback of getJSON and then use the back button on the browser, the displayed page is not the exepted one. (tested on FF3.5).

Here is a test code :

<a class="btTest">Test</a> <script type="text/javascript"> $('.btTest').click(function() { $.getJSON(' http://maps.google.com/maps/geo?callback=?', function() { window.location = ' http://google.fr'; }); }); </script>

I found a hack :

Handle JSONP-style loading window[ jsonp ] = function(tmp){setTimeout(function() {

data = tmp; success(); complete(); Garbage collect window[ jsonp ] = undefined; try{ delete window[ jsonp ]; } catch(e){} if ( head )

head.removeChild( script );

}, 1);};

(wont work correctly on jsfiddle)

When a script loads and immediately redirects the page, Firefox pretends that it like the server performed a 3xx direct and removes the previous page from the browser history. This has nothing to do with jQuery.

 broken  works, using onload  works, using setTimeout

This does not happen if the assignment to window.location happens from the script’s onload method, or if it is deferred using setTimeout.

Workaround: Do not modify the location of the window using window.location in response to a JSONP call without wrapping it in setTimeout.
