Passing data to a bootstrap modal

JavascriptJqueryasp.net MvcTwitter Bootstrap

Javascript Problem Overview

I've got a couple of hyperlinks that each have an ID attached. When I click on this link, I want to open a modal ( http://twitter.github.com/bootstrap/javascript.html#modals ), and pass this ID to the modal. I searched on google, but I couldn't find anything that could help me.

This is the code:

<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>

Which should open:

<div class="modal hide" id="addBookDialog">
    <div class="modal-body">
        <input type="hidden" name="bookId" id="bookId" value=""/>
    </div>
</div>

With this piece of code:

$(document).ready(function () {
    $(".open-AddBookDialog").click(function () {
        $('#bookId').val($(this).data('id'));
        $('#addBookDialog').modal('show');
    });
});

However, when I click the hyperlink, nothing happens. When I give the hyperlink <a href="#addBookDialog" ...>, the modal opens just fine, but it does't contain any data.

I followed this example: https://stackoverflow.com/questions/10379624/how-to-pass-values-arguments-to-modal-show-function-in-twitter-bootstrat

(and I also tried this: https://stackoverflow.com/questions/7845866/how-to-set-the-input-value-in-a-modal-dialogue)

Solution 1 - Javascript

I think you can make this work using jQuery's .on event handler.

Here's a fiddle you can test; just make sure to expand the HTML frame in the fiddle as much as possible so you can view the modal.

http://jsfiddle.net/Au9tc/605/

HTML

<p>Link 1</p>
<a data-toggle="modal" data-id="ISBN564541" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a>

<p>&nbsp;</p>


<p>Link 2</p>
<a data-toggle="modal" data-id="ISBN-001122" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a>
    
<div class="modal hide" id="addBookDialog">
 <div class="modal-header">
    <button class="close" data-dismiss="modal">×</button>
    <h3>Modal header</h3>
  </div>
    <div class="modal-body">
        <p>some content</p>
        <input type="text" name="bookId" id="bookId" value=""/>
    </div>
</div>

JAVASCRIPT

$(document).on("click", ".open-AddBookDialog", function () {
     var myBookId = $(this).data('id');
     $(".modal-body #bookId").val( myBookId );
     // As pointed out in comments, 
     // it is unnecessary to have to manually call the modal.
     // $('#addBookDialog').modal('show');
});

Solution 2 - Javascript

Here is a cleaner way to do it if you are using Bootstrap 3.2.0.

Link HTML

<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>

Modal JavaScript

//triggered when modal is about to be shown
$('#my_modal').on('show.bs.modal', function(e) {

    //get data-id attribute of the clicked element
    var bookId = $(e.relatedTarget).data('book-id');

    //populate the textbox
    $(e.currentTarget).find('input[name="bookId"]').val(bookId);
});

Solution 3 - Javascript

Here's how I implemented it working from @mg1075's code. I wanted a bit more generic code so as not to have to assign classes to the modal trigger links/buttons:

Tested in Twitter Bootstrap 3.0.3.

HTML

<a href="#" data-target="#my_modal" data-toggle="modal" data-id="my_id_value">Open Modal</a>

JAVASCRIPT

$(document).ready(function() {

  $('a[data-toggle=modal], button[data-toggle=modal]').click(function () {

    var data_id = '';

    if (typeof $(this).data('id') !== 'undefined') {

      data_id = $(this).data('id');
    }

    $('#my_element_id').val(data_id);
  })
});

Solution 4 - Javascript

Bootstrap 4.3 - use code from below snippet - more here

$('#exampleModal').on('show.bs.modal', function (event) {
  let bookId = $(event.relatedTarget).data('bookid') 
  $(this).find('.modal-body input').val(bookId)
})


a.btn.btn-primary.open-AddBookDialog {color: white }


<!-- Initialize Bootstrap 4 -->

    <div class="modal-content">
    
      <div class="modal-body">
        <input type="hidden" name="bookId" id="bookId" value=""/>
        <input type="text" class="form-control" id="recipient-name">    
      </div>
      
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
      </div>

    </div>
  </div>
</div>

Solution 5 - Javascript

If you are on bootstrap 3+, this can be shortened a bit further if using Jquery.

HTML

<a href="#" data-target="#my_modal" data-toggle="modal" class="identifyingClass" data-id="my_id_value">Open Modal</a>

<div class="modal fade" id="my_modal" tabindex="-1" role="dialog" aria-labelledby="my_modalLabel">
<div class="modal-dialog" role="dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
            <h4 class="modal-title" id="myModalLabel">Modal Title</h4>
        </div>
        <div class="modal-body">
            Modal Body
            <input type="hidden" name="hiddenValue" id="hiddenValue" value="" />
        </div>
        <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">No</button>
            <button type="button" class="btn btn-primary">Yes</button>
        </div>
    </div>
</div>

JQUERY

<script type="text/javascript">
    $(function () {
        $(".identifyingClass").click(function () {
            var my_id_value = $(this).data('id');
            $(".modal-body #hiddenValue").val(my_id_value);
        })
    });
</script>

Solution 6 - Javascript

Your code would have worked with correct modal html structure.

$(function(){
  $(".open-AddBookDialog").click(function(){
     $('#bookId').val($(this).data('id'));
    $("#addBookDialog").modal("show");
  });
});


<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>


<a data-id="@book.Id" title="Add this item" class="open-AddBookDialog">Open Modal</a>

<div id="addBookDialog" class="modal fade" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-body">
       <input type="hidden" name="bookId" id="bookId" value=""/>
      </div>
    
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
</html>

Solution 7 - Javascript

This is so easy with jquery:

If below is your anchor link:

<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>

In the show event of your modal you can access to the anchor tag like below

//triggered when modal is shown
$('#modal_id').on('shown.bs.modal', function(event) {

    // The reference tag is your anchor tag here
    var reference_tag = $(event.relatedTarget); 
    var id = reference_tag.data('id')
    // ...
    // ...
})

Solution 8 - Javascript

Bootstrap 4.0 gives an option to modify modal data using jquery: https://getbootstrap.com/docs/4.0/components/modal/#varying-modal-content

Here is the script tag on the docs :

$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})

It works for the most part. Only call to modal was not working. Here is a modification on the script that works for me:

$(document).on('show.bs.modal', '#exampleModal',function(event){
... // same as in above script
})

Solution 9 - Javascript

I'm with bootstrap 5 and cannot show() the modal with script myself due to constraints outside my control, so I'm depending on properties data-bs-toggle and data-bs-target of the button that pops up the modal.

Bootstrap exposes a few events though (https://getbootstrap.com/docs/5.0/components/modal/), to which we can hook code like so:

document.getElementById('idModal').addEventListener('show.bs.modal', (e) => {
    console.log(e.relatedTarget);
});

In relatedTarget, we'll find the specified data attributes in dataset, e.g. if we have an element that looks like this:

<button
    class="btn btn-secondary"
    data-id="fk_articles"
    data-bs-toggle="modal"
    data-bs-target="#documentationModal">
        Documentation
</button>

Then we can reach fk_articles through:

console.log( e.relatedTarget.dataset.id )

Solution 10 - Javascript

I find this approach useful:

Create click event:

$( button ).on('click', function(e) {
    let id = e.node.data.id;

    $('#myModal').modal('show', {id: id});
});

Create show.bs.modal event:

$('#myModal').on('show.bs.modal', function (e) {

     // access parsed information through relatedTarget
     console.log(e.relatedTarget.id);

});

Extra:

Make your logic inside show.bs.modal to check whether the properties are parsed, like for instance as this: id: ( e.relatedTarget.hasOwnProperty( 'id' ) ? e.relatedTarget.id : null )

Solution 11 - Javascript

Try with this

$(function(){
 //when click a button
  $("#miButton").click(function(){
    $(".dynamic-field").remove();
    //pass the data in the modal body adding html elements
    $('#myModal .modal-body').html('<input type="hidden" name="name" value="your value" class="dynamic-field">') ;
    //open the modal
    $('#myModal').modal('show') 
  })
})

Solution 12 - Javascript

This is how you can send the id_data to a modal :

<input
    href="#"
    data-some-id="uid0123456789"
    data-toggle="modal"
    data-target="#my_modal"
    value="SHOW MODAL"
    type="submit"
    class="btn modal-btn"/>

<div class="col-md-5">
  <div class="modal fade" id="my_modal">
   <div class="modal-body modal-content">
     <h2 name="hiddenValue" id="hiddenValue" />
   </div>
   <div class="modal-footer" />
</div>

And the javascript :

    $(function () {
     $(".modal-btn").click(function (){
       var data_var = $(this).data('some-id');
       $(".modal-body h2").text(data_var);
     })
    });

Solution 13 - Javascript

For updating an href value, for example, I would do something like:

<a href="#myModal" data-toggle="modal" data-url="http://example.com">Show modal</a>

$('#myModal').on('show.bs.modal', function (e) {
    var url = $(e.relatedTarget).data('url');
    $(e.currentTarget).find('.any-class').attr("href", "url");
})

Solution 14 - Javascript

Found this works for me:

In the link:

<button type="button" class="btn btn-success" data-toggle="modal" data-target="#message<?php echo $row['id'];?>">Message</button>

In the modal:

<div id="message<?php echo $row['id'];?>" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <?php echo $row['id'];?>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

Solution 15 - Javascript

You can try simpleBootstrapDialog. Here you can pass title, message, callback options for cancel and submit etc...

To use this plugin include simpleBootstrapDialog.js file like below

<script type="text/javascript" src="/simpleDialog.js"></script>

Basic Usage

<script type="text/javascript>
$.simpleDialog();
</script>

Custom Title and description

$.simpleDialog({
  title:"Alert Dialog",
  message:"Alert Message"
});

With Callback

<script type="text/javascript>
$.simpleDialog({
    onSuccess:function(){
        alert("You confirmed");
    },
    onCancel:function(){
        alert("You cancelled");
    }
});
</script>
