Wordpress AJAX Login

Question

I am trying to build a custom wordpress ajax login form but I can't get it sorted. Here is the codes I use:

HTML:

            <form class="well form-inline" id="login">
                <div class="rowmargin">
                    <h4>Login</h4>
                </div>
                <div class="rowmargin">
                    <input type="text" name="username" id="loginUsername" class="input-medium" placeholder="Username">
                    <input type="password" name="password" id="loginPassword" class="input-medium" placeholder="Password">
                </div>
                <a class="btn btn-primary" id="loginButton"><i class="icon-check icon-white"></i> Login</a>
            </form>

JS:

    <script type="text/javascript">

        $(document).ready(function() {

            $("#loginButton").click(function() {    

                var username = $('#loginUsername').val();
                var password = $('#loginPassword').val();
                var rememberme = "forever";
                var redirect = '<?php bloginfo('url'); ?>';

                var data = {
                    user_login:     username,
                    user_password:  password,
                    remember:       rememberme,
                    redirect_to:    redirect
                }

                $.ajax({
                    url: '<?php bloginfo('url'); ?>/wp-login.php',
                    data: data,
                    type: 'GET',
                    dataType: 'jsonp',
                    success: function( result ) {
                        if (result.success==1) {
                            alert("Ok!");
                        } else {
                            alert("Not Ok!");
                        }
                    }
                }); 

            });

        });

        </script> <!-- Login Script --->

Can someone tell me what am I doing wrong here?

WordPress: Simple Ajax Login Form

<form id="login" action="login" method="post">
    <h1>Site Login</h1>
    <p class="status"></p>
    <label for="username">Username</label>
    <input id="username" type="text" name="username">
    <label for="password">Password</label>
    <input id="password" type="password" name="password">
    <a class="lost" href="<?php echo wp_lostpassword_url(); ?>">Lost your password?</a>
    <input class="submit_button" type="submit" value="Login" name="submit">
    <a class="close" href="">(close)</a>
    <?php wp_nonce_field( 'ajax-login-nonce', 'security' ); ?>
</form>

--

<?php
//add this within functions.php
function ajax_login_init(){

    wp_register_script('ajax-login-script', get_template_directory_uri() . '/ajax-login-script.js', array('jquery') ); 
    wp_enqueue_script('ajax-login-script');

    wp_localize_script( 'ajax-login-script', 'ajax_login_object', array( 
        'ajaxurl' => admin_url( 'admin-ajax.php' ),
        'redirecturl' => home_url(),
        'loadingmessage' => __('Sending user info, please wait...')
    ));

    // Enable the user with no privileges to run ajax_login() in AJAX
    add_action( 'wp_ajax_nopriv_ajaxlogin', 'ajax_login' );
}

// Execute the action only if the user isn't logged in
if (!is_user_logged_in()) {
    add_action('init', 'ajax_login_init');
}


function ajax_login(){

    // First check the nonce, if it fails the function will break
    check_ajax_referer( 'ajax-login-nonce', 'security' );

    // Nonce is checked, get the POST data and sign user on
    $info = array();
    $info['user_login'] = $_POST['username'];
    $info['user_password'] = $_POST['password'];
    $info['remember'] = true;

    $user_signon = wp_signon( $info, false );
    if ( is_wp_error($user_signon) ){
        echo json_encode(array('loggedin'=>false, 'message'=>__('Wrong username or password.')));
    } else {
        echo json_encode(array('loggedin'=>true, 'message'=>__('Login successful, redirecting...')));
    }

    die();
}

Create a file ajax-login-script.js within theme's directory and paste this js

jQuery(document).ready(function($) {

    // Show the login dialog box on click
    $('a#show_login').on('click', function(e){
        $('body').prepend('<div class="login_overlay"></div>');
        $('form#login').fadeIn(500);
        $('div.login_overlay, form#login a.close').on('click', function(){
            $('div.login_overlay').remove();
            $('form#login').hide();
        });
        e.preventDefault();
    });

    // Perform AJAX login on form submit
    $('form#login').on('submit', function(e){
        $('form#login p.status').show().text(ajax_login_object.loadingmessage);
        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajax_login_object.ajaxurl,
            data: { 
                'action': 'ajaxlogin', //calls wp_ajax_nopriv_ajaxlogin
                'username': $('form#login #username').val(), 
                'password': $('form#login #password').val(), 
                'security': $('form#login #security').val() },
            success: function(data){
                $('form#login p.status').text(data.message);
                if (data.loggedin == true){
                    document.location.href = ajax_login_object.redirecturl;
                }
            }
        });
        e.preventDefault();
    });

});

You would need to use wp function for login.

http://codex.wordpress.org/Function_Reference/wp_signon

Then use ajax to access this function to log in. You could write a log in function in functions.php
