Bind a function to Twitter Bootstrap Modal Close

Question

I am using the Twitter Bootstrap lib on a new project and I want for part of the page to refresh and retrieve the latest json data on modal close. I dont see this anywhere in the documentation can someone point it out to me or suggest a solution.

Two problems with using the documented methods

 $('#my-modal').bind('hide', function () {
   // do something ...
 });

I attach a "hide" class to the modal already so it does not display on page load so that would load twice

even if I remove the hide class and set the element id to display:none and add console.log("THE MODAL CLOSED"); to the function above when I hit close nothing happens.

Answer 1

Bootstrap 3 & 4

$('#myModal').on('hidden.bs.modal', function () {
    // do something…
});

Bootstrap 3: getbootstrap.com/javascript/#modals-events

Bootstrap 4: getbootstrap.com/docs/4.1/components/modal/#events

Bootstrap 2.3.2

$('#myModal').on('hidden', function () {
    // do something…
});

See getbootstrap.com/2.3.2/javascript.html#modals → Events

Answer 2

Bootstrap 4

$('#my-modal').on('hidden.bs.modal', function () {
  window.alert('hidden event fired!');
});

See this JSFiddle for a working example:

See the Modal Events section of the docs here:

Answer 3

Starting Bootstrap 3 (edit: still the same in Bootstrap 4) there are 2 instances in which you can fire up events, being:

1. When modal "hide" event starts

$('#myModal').on('hide.bs.modal', function () { 
    console.log('Fired at start of hide event!');
});  

2. When modal "hide" event finished

$('#myModal').on('hidden.bs.modal', function () {
    console.log('Fired when hide event has finished!');
});

Answer 4

In stead of "live" you need to use "on" event, but assign it to the document object:

Use:

$(document).on('hidden.bs.modal', '#Control_id', function (event) {
// code to run on closing
});

Answer 5

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

Answer 6

Boootstrap 5+ #ES6+

fewer dependencies -> Like other frameworks, Bootstrap will go back to standard thanks to new event methods

var myModalEl = document.getElementById('myModalID');
myModalEl.addEventListener('hidden.bs.modal', function (event) {
    // do something...
});

Answer 7

Bootstrap provide events that you can hook into modal, like if you want to fire a event when the modal has finished being hidden from the user you can use hidden.bs.modal event like this

    /* hidden.bs.modal event example */
    $('#myModal').on('hidden.bs.modal', function () {
          window.alert('hidden event fired!');
    })

Check a working fiddle here read more about modal methods and events here in Documentation

Answer 8

Bootstrap 4:

$('#myModal').on('hidden.bs.modal', function (e) {
   // call your method
})

hide.bs.modal: This event is fired immediately when the hide instance method has been called.

hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).

Answer 9

I would do it like this:

$('body').on('hidden.bs.modal', '#myModal', function(){ //this call your method });

The rest has already been written by others. I also recommend reading the documentation:jquery - on method

Answer 10

I've seen many answers regarding the bootstrap events such as hide.bs.modal which triggers when the modal closes.

There's a problem with those events: any popups in the modal (popovers, tooltips, etc) will trigger that event.

There is another way to catch the event when a modal closes.

$(document).on('hidden','#modal:not(.in)', function(){} );

Bootstrap uses the in class when the modal is open. It is very important to use the hidden event since the class in is still defined when the event hideis triggered.

This solution will not work in IE8 since IE8 does not support the Jquery :not() selector.

Answer 11

if you want to fire a function on every modal close, you can use this method,

$(document).ready(function (){
    $('.modal').each(function (){
        $(this).on('hidden.bs.modal', function () {
            //fires when evey popup close. Ex. resetModal();
        });
    });
});

So you don't need to specify modal ids every time.

Answer 12

I was having the same issues as some with

$('#myModal').on('hidden.bs.modal', function () {
// do something… })

You need to place this at the bottom of the page, placing it at the top never fires the event.
