javascript - Why does Ajax post data to localhost rather than the provided URL? -

so using ajax post form server, however, instead of sending form url, sends itself.

here code

$("#psignup").click(function() {     $.ajax({            type: "post",            url: "example/default/mobile_user_register",            data: $("#patientsignup").serialize(), // serializes form's elements.            success: function(data)            {                alert(data); // show response php script.            }          });      return false; // avoid execute actual submit of form. }); 

in browser, appears send http://localhost:8080/?email=asdfa%40asd.com&password=asd&repeatpassword=&firstname=asd&username=&lastname=asd

what looking is, of course, "http://example.com/default/mobile_user_register?xxxxxxxxxxxxxx". can me understand why isn't working?

use jsonp

$.ajax({     url: "http://example.com/default/mobile_user_register?xxxxxxxxxxxxxx",     datatype: 'jsonp', //use jsonp data type in order perform cross-domain ajax      crossdomain: true,      data: data,      success: callback,     error: callback });
