Create a JQuery plugin for twitter-bootstrap “Confirm Modal popup”

There is a situation that we need user to confirm before they proceed their action. You don’t want to accidently delete very important information. So I come up the idea to extend the bootstrap modal popup to create a confirm modal before calling the function to delete some stuff.

(function ($) {
        //pass the options variable to the function
        confirmModal: function (options) {
            var html = '<div class="modal" id="confirmContainer"><div class="modal-header"><a class="close" data-dismiss="modal">×</a>' +
            '<h3>#Heading#</h3></div><div class="modal-body">' +
            '#Body#</div><div class="modal-footer">' +
            '<a href="#" class="btn btn-primary" id="confirmYesBtn">Confirm</a>' +
            '<a href="#" class="btn" data-dismiss="modal">Close</a></div></div>';

            var defaults = {
                heading: 'Please confirm',
                body:'Body contents',
                callback : null

            var options = $.extend(defaults, options);
            html = html.replace('#Heading#',options.heading).replace('#Body#',options.body);
            var context = $(this);


Basically,  all you need to do in the UI, is to create a link to activate the confirm modal, and a empty div for my plugin to work with. With options, you can pass in modal heading and modal content body. With callback method, is your logic to delete stuff or something you want to do originally.

<script type="text/javascript">
$(function () {
$("#openConfirmModal").click(function () {
heading: 'Confirm to delete',
body: 'Are you sure you want to delete this record?',
callback: function () {
alert('callback test');
<a href="#" id="openConfirmModal">Open Confirm Modal</a>
<div id="confirmDiv"></div>

  1. I have a grid with delete buttons on each row. I need to display a confirmation modal before actually deleting the selected row and this seems to be a really nice solution since I’m already using Bootstrap.
    Is there a way to pass the row ID to the modal so when I click “Confirm” it actually submits a form passing this ID to my controller (ASP.NET MVC 3)?

    And thanks for sharing it! 🙂

    1. In the grid, each row for you button, you can have a onclick event,

      then you define the deleteConfirm(id) function and call the confirm modal using js.

      you have id to pass in and do a ajax post back to controller.


      1. I have put a form with a hidden ID input, then I gave each row a button with a onclick event that sets the form’s hidden input to the correct ID and then calls the modal with a form.submit() callback. 🙂
