How to hide Bootstrap modal from javascript?

2019-01-16 01:28发布

I've read the posts here, the Bootstrap site, and Googled like mad - but can't find what I'm sure is an easy answer...

I have a Bootstrap modal that I open from a link_to helper like this:

<%= link_to "New Contact", new_contact_path, {remote: true, 'data-toggle' => 'modal', 'data-target' => "#myModal",  class: "btn btn-primary"} %>

In my ContactsController.create action, I have code that creates Contact then passes off to create.js.erb. In create.js.erb, I have some error handling code (a mix of ruby and javascript). If everything goes well, I want to close the modal.

This is where I'm having trouble. I can't seem to dismiss the modal when all goes well.

I've tried $('#myModal').modal('hide'); and this has no effect. I've also tried $('#myModal').hide(); which causes the modal to dismiss but leaves the backdrop.

Any guidance on how to close the modal and/or dismiss the backdrop from within create.js.erb?

Edit

Here's the markup for myModal:

<div class="modal hide" id="myModal" >
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Add Contact</h3>
    <div id="errors_notification">
    </div>
  </div>
  <div class="modal-body">
    <%= form_for :contact, url: contacts_path, remote: true do |f| %>  
      <%= f.text_field :first_name, placeholder: "first name" %>
      <%= f.text_field :last_name, placeholder: "last name" %>
      <br>
      <%= f.submit "Save", name: 'save', class: "btn btn-primary" %>
      <a class="close btn" data-dismiss="modal">Cancel</a>
    <% end %>
  </div>
  <div class="modal-footer">
  </div>
</div>

I was experiencing the same problem, and after a bit of experimentation I found a solution. In my click handler, I needed to stop the event from bubbling up, like so:

$("a.close").on("click", function(e){
  $("#modal").modal("hide");
  e.stopPropagation();
});

I realize this is an old question, but I found that none of these were really what I was looking for exactly. It seems to be caused by trying to close the modal before it's finished showing.

My solution was based on @schoonie23's answer but I had to change a few things.

First, I declared a global variable at the top of my script:

<script>
    var closeModal = false;
    ...Other Code...

Then in my modal code:

$('#myModal').on('show.bs.modal', function (event) {
    ...Some Code...
    if (someReasonToHideModal) {
        closeModal = true;
        return;
    }
    ...Other Code...

Then this: (Note the name 'shown.bs.modal' indicating that the modal has shown completely as opposed to 'show' that triggers when the show event is called. (I originally tried just 'shown' but it did not work.)

$('#myModal').on('shown.bs.modal', function (event) {
    if (closeEditModal) {
        $('#myModal').modal('hide');
        closeModal = false;
    }
});

Hope this saves someone the extra research some day. I spent a bit looking for a solution before I came up with this.

Here is the doc: http://getbootstrap.com/javascript/#modals-methods

Here is the method: $('#myModal').modal('hide')

If you need to open several times the modal with different content, I suggest to add (in you main js):

$('body').on('hidden.bs.modal', '.modal', function () {
      $(this).removeData('bs.modal');
    });

So you will clean the content for the next opening and avoid a kind of caching

With the modal open in the browser window, use the browser's console to try

$('#myModal').modal('hide');

If it works (and the modal closes) then you know that your close Javascript is not being sent from the server to the browser correctly.

If it doesn't work then you need to investigate further on the client what is happening. Eg make sure that there aren't two elements with the same id. Eg does it work the first time after page load but not the second time?

Browser's console: firebug for firefox, the debugging console for Chrome or Safari, etc.

This is the bad practice but you can use this technique to close modal by calling close button in javascript. This will close modal after 3 seconds.

What we found was that there was just a slight delay between the call to our server code and the return to the success call back. If we wrapped the call to the server in the $("#myModal").on('hidden.bs.modal', function (e) handler and then called the $("#myModal").modal("hide"); method, the browser would hide the modal and then invoke the server side code.

Again, not elegant but functional.

 function myFunc(){
        $("#myModal").on('hidden.bs.modal', function (e) {
            // Invoke your server side code here.
        });
        $("#myModal").modal("hide");
 };

As you can see, when myFunc is invoked, it will hide the modal and then invoke the server side code.
