use like this: $.post('/testurl/', { param1: "value1" }, function(data) {alert(data)});
In firefox ,when I submit this ajax request,in the firebug it says,"Loading...",but no return. in IE it works fine. but if I change the "post" to "get" ,it works well,or change {param1:'value1'} to a empty {},it also works well, why? how can I post data in ajax use jquery.
