$（“＃”）。submit与Ajax刷新页面一起提交

Question

Not sure what is the issue as this code was working fine some time earlier, I am trying to submit my form using Ajax and this is my code

Ajax Code

 $(function() {
 $("#login").submit(function() {
   $('#signinPane').showLoading();
 $("#loginError").hide();
 var data = $(this).serializeObject();
    $.ajax({
        'type': "POST",
         'url': "<c:url value="/shop/customer/j_spring_security_check"/>",
         'data':data,
         'success': function(result) {

         }
       });

     return false;
   });
});

HTML Code

<form id="login" method="post" accept-charset="UTF-8">
<input id="userName" style="margin-bottom: 15px;" type="text" name="j_username" size="30" />
<input id="password" style="margin-bottom: 15px;" type="password" name="j_password" size="30" />
<button type="submit" id="login-button"></button>
</form>

My issue is, when I am clicking on submit button, page is getting refresh and no Ajax call is being submitted at all. Not sure what is happening.

Answer 1

I think you need to call preventDefault on event object.

Returning false is okay when you're in the vanilla JS handler, and you're not.

Answer 2

Try passing the event as a parameter and then calling e.preventDefault()

jsfiddle Documentation

$(function() {
    $("#login").submit(function(e) {
        e.preventDefault();
        $('#signinPane').showLoading();
        $("#loginError").hide();
        var data = $(this).serializeObject();
        $.ajax({
            'type': "POST",
            'url': "<c:url value="/shop/customer/j_spring_security_check"/>",
            'data':data,
            'success': function(result) {

            }
        });
    });
});

Answer 3

use

event.preventDefault();


$("#login").submit(function(event) {
    event.preventDefault();
    $('#signinPane').showLoading();

This will prevent default form submit characteristic.

Answer 4

Try:

$("#login").submit(function(e) {
 e.preventDefault();
 e.stopPropagation();
