带重定向的JavaScript确认框

Question

I need to ask a user to confirm the delete of his post. I managed it using the confirm function from jQuery but I wanted to create an overlay box with more customization options and after browsing the web I came up with this:

Info: CMS in question is Wordpress

So first the theme: index.php:

<li class="EditDel">
    <?php u_delete_post_link('Delete', '', ''); ?>
</li>

PHP function:

function u_delete_post_link($link = 'Delete This', $before = '', $after = '') {
    global $post;

    $message = "Are you sure you want to delete ".get_the_title($post->ID)." ?";
    $delLink = wp_nonce_url( get_bloginfo('url') . "/wp-admin/post.php?action=delete&post=" . $post->ID, 'delete-post_' . $post->ID);
    $htmllink = "<a href='' onclick = \" u_ask_go('".$message."','".$delLink."' ) \"/>".$link."</a>";
    echo $before . $htmllink . $after;
}

Now for the actual problem the link above fires a js function with the message and the link:

function u_ask_go(msg,link)
{   
    u_confirm(msg,link, function () {
        window.location.href = arguments[0];
    });
}

and the u_confirm function:

function u_confirm(message, link, callback) {
    jQuery('#confirm').modal({
        closeHTML: "<a href='#' title='Close' class='modal-close'>x</a>",
        position: ["20%",],
        overlayId: 'confirm-overlay',
        containerId: 'confirm-container', 
        onShow: function (dialog) {
            var modal = this;

            modal.link = link;

            //console.log(modal.link);

            jQuery('.message', dialog.data[0]).append(message);


            // if the user clicks "yes"
            jQuery('.yes', dialog.data[0]).click(function () {
                // call the callback

                if (jQuery.isFunction(callback)) {
                    //console.log(modal.link);
                    callback.apply(modal.link);
                }
                // close the dialog
                modal.close(); // or $.modal.close();
            });
        }
    });
}

Problem1: The callback function does not fire

Problem2: The dialog collapses and the link executes without user pressing anything

Observation: Before the modal div is appended the link variable is visible but not in the function on the dialog yes button seems not visible

Hope someone can help

EDIT (HTML buildup):

    <!-- modal content -->
    <div id='confirm'>
        <div class='header'><span>Confirm</span></div>
        <div class='message'></div>
        <div class='buttons'>
            <div class='no simplemodal-close'>No</div><div class='yes'>Yes</div>
    </div>
    </div>
    <!-- preload images -->
    <div style='display:none'>
        <img src='img/confirm/header.gif' alt='' />
        <img src='img/confirm/button.gif' alt='' />
    </div>

EDIT2:

echo wp_enqueue_script('simplemodal', $blogroot.'/js/jquery.js');
echo wp_enqueue_script('simplemodal', $blogroot.'/js/jquery.simplemodal.js', array("jquery"));
echo wp_enqueue_script('confirmtest', $blogroot.'/js/confirmtest.js', array("jquery"));

The best thing to do is not to put your function in an onClick="" attribute, you should use jQuery to call the function like so, and store your variables in custom data attributes (info here )

jQuery:

$('a#confirmDelete').live('click', function(e) {

    // Prevent default
    e.preventDefault();

    var msg = $(this).attr('data-message');
    var link = $(this).attr('data-del-link');

    u_confirm(msg,link, function () {
        window.location.href = arguments[0];
    });
});

HTML:

function u_delete_post_link($link = 'Delete This', $before = '', $after = '') {
    global $post;

    $message = "Are you sure you want to delete ".get_the_title($post->ID)." ?";
    $delLink = wp_nonce_url( get_bloginfo('url') . "/wp-admin/post.php?action=delete&post=" . $post->ID, 'delete-post_' . $post->ID);
    $htmllink = "<a href="#" id="confirmDelete" data-message="' . $message . '" data-del-link="' . $delLink . '" />".$link."</a>";
    echo $before . $htmllink . $after;
}

Answer 2

Ok got it to work Thanks again to Coulton to point me in the right direction. But just for the meaning of completing the answer:

1. I had to include the scripts the right way in the functions.php file not the header( note: the first parameter needs to differ for every script thats why it didnt load correcty in the first place):

   echo wp_enqueue_script('jquery', $blogroot.'/js/jquery.js'); echo wp_enqueue_script('simplemodal', $blogroot.'/js/jquery.simplemodal.js', array("jquery")); echo wp_enqueue_script('confirmtest', $blogroot.'/js/confirmtest.js', array("jquery"));

2. In my case the following 2 lines didn't work:

   var msg = $(this).attr('data-message');

   var link = $(this).attr('data-del-link');

Had to replace them with this:

var msg = jQuery(this).attr('data-message');
var link = jQuery(this).attr('data-del-link');
