Automatic Login

I'm trying to automatically login a user. The JavaScript code below here actually does that but only when I remove the 'login/submit' div (), and then stops working when I include the 'div'. I can't remove this 'div' as that is my submit button. I don't know how to get around this problem, any help will be appreciated.



<form name="EventConfirmRedirection" class="Form" method="post" action="index.php" id="myForm" data-ajax="false">
<div class="user_login3"><input style="text-transform:lowercase" type="text" name="username" id="username" placeholder="username"></div>
<div class="user_login3"><input type="password" name="password" id="password" placeholder="password"></div>

<div style="margin-left:5%; width:45%; font-size:5px;">
<input data-theme="c" type="checkbox" id="rememberMe" name="rememberMe"/>
<label for="rememberMe"><span style="font-size:12px">remember me</span></label>

<div style="margin-left:5%; color:#FF0000; font-weight:bold" id="error"></div>

<div class="login"><input type="submit" value="LOGIN" name="submit" data-theme="e" id="submit"></div>



$(document).ready(function() {

"use strict";

if (window.localStorage.checkBoxValidation && window.localStorage.checkBoxValidation !== '') {
$('#rememberMe').attr('checked', 'checked');
} else {

$('#rememberMe').click(function() {

if ($('#rememberMe').is(':checked')) {
// save username and password
window.localStorage.userName = $('#username').val();
window.localStorage.passWord = $('#password').val();
window.localStorage.checkBoxValidation = $('#rememberMe').val();
} else {
window.localStorage.userName = '';
window.localStorage.passWord = '';
window.localStorage.checkBoxValidation = '';


$(document).ready(function() {

"use strict";

$("#submit").click( function(e) {

if( $("#username").val() === "" || $("#password").val() === "" )
$("div#error").html("Both username and password are required");
} else {
$.post( $("#myForm").attr("action"),
$("#myForm :input").serializeArray(),
function(data) {

$("#myForm").submit( function() {
return false;


Answer Source

"submit is not a function" means that you named your submit button or some other element submit. Rename the button to btnSubmit and your call will magically work. Any of the form element name and id should not be submit, otherwise form.submit will refer to that element rather than submit function.

When you name the button submit, you override the submit() function on the form.

So changing the div/submit like this will work for you

<div class="login"><input type="submit" value="LOGIN" name="btnSubmit" data-theme="e" id="btnSubmit"></div>

And if you don't want to change the button name then you might call the submit function natively aswell, which looks a bit dirty..;
