Show event for all Bootstrap Modals on the page

Question

I'm trying to do something (in this case some statistics) whenever a Bootrap modal is opened.

I know, I can ad an event listener like this to a modal:

$('#modal-content').on('shown.bs.modal', function() {
   alert('do something');
});

But is there a way to have a listener for all modals on the page? Bonus question: even for those who are inserted by Javascript?

I have thought about something like this:

jQuery('.modal[role="dialog"]').on('show.bs.modal', function() {
   alert('do something');
});

But I hope that there's a better way and something that will work for modals that are inserted by Javascript.

Answer 1

This ought to do the trick for you--it catches the event when it bubbles up to the document level, so that should catch them all:

$(document).on('shown.bs.modal', function() {
   alert('do something');
});

If you know the ids ahead of time, you could just list them out:

$('#modalOne, #modalTwo').on('shown.bs.modal', function() {
   alert('do something');
});

Or better yet, if you are creating them programmatically as well as in html and are using a common prefix for the id, you can use the following:

$("div[id^='modal']").on('shown.bs.modal', function() {
   alert('do something');
});
