jquery - How to make an ajax request in login form with spring security? -

i read several articles , followed them didn't work in case. login form follows:-

<div style="text-align: center; padding: 30px; border: 1px solid; width: 300px;">      <form method="post"           action='j_spring_security_check' id="login_form" >        <table>          <tr>            <td colspan="2" style="color: red">${message}</td>          </tr>           <tr>            <td>user name:</td>             <td><input type="text" name="j_username" id="uname"  value='<c:if test="${not empty param.login_error}">                                                      <c:out value="${spring_security_last_username}"/>                                                      </c:if>' /></td>          </tr>           <tr>            <td>password:</td>             <td><input type="password" name="j_password" /></td>          </tr>           <tr>            <td colspan="1"><input type="submit" value="login" /></td>             <td colspan="1"><input name="reset" type="reset" /></td>          </tr>        </table>      </form>    </div> 

i making ajax request follows:-

<script>          $("#login_form").submit(function(e){             var formurl = $("#login_form").attr("action");             var postdata=$("#login_form").serializearray();             $.ajax({                 url:"/abhishekchat/j_spring_security_check",                 method:post,                 data:postdata,                 beforesend: function (xhr) {                      xhr.setrequestheader("x-ajax-call", "true");                  },                  success:function(response){console.log("success");},                 error:function(response){console.log("operation failed");}              });             e.preventdefault();         });         $("#login_form").submit();     </script>
