How do I bind Twitter Bootstrap tooltips to dynamically created elements?

I'm using Twitter bootstrap tooltips with javascript like the following:

$('a[rel=tooltip]').tooltip();

My markup looks like this:

<a rel="tooltip" title="Not implemented" class="btn"><i class="icon-file"></i></a>

This works fine, but I add <a> elements dynamically and the tooltips aren't showing up for those dynamic elements. I know it's because I only bind .tooltip() once when the document is finished loaded with the typical jquery $(document).ready(function() functionality.

How can I bind this to dynamically created elements? Usually I would do this via the jquery live() method. However, what is the event that I use to bind? I'm just not sure how to hook up the bootstrap .tooltip() with jquery .live().

I've found one way to make this work is something like this:

/* Add new 'rows' when plus sign is clicked */
$("a.add").live('click', function () {
    var clicked_li = $(this).parent('li');
    var clone = clicked_li.clone();

    clone.find(':input').each(function() {
        $(this).val('');
    });

    clicked_li.after(clone);
    $('a[rel=tooltip]').tooltip();
});

This works, but seems kind of hackish. I'm also calling the exact same .tooltip() line in the $(ready) call. So, do the elements that exist when the page first loads and match that selector end up with the tooltip twice?

I don't see any problems with this approach. I'm just looking for a best practice or understanding of the behavior.

In Bootstrap 5, which doesn't use jQuery, you can do this:

const btn = document.createElement('button');
btn.innerHTML = 'Click me';
btn.dataset['toggle'] = 'tooltip';
btn.dataset['placement'] = 'top';
btn.title = 'Your Tooltip Here';
new bootstrap.Tooltip(btn);

document.getElementById('parent').appendChild(btn);

<div id="parent"></div>

Rather than search it in full Body. One could just use dynamic title option already available in such scenarios I think:

$btn.tooltip({
  title: function(){
    return $(this).attr('title');
  }
});

If you have multiple tooltip configurations that you want to initialise, this works well for me. 

$("body").tooltip({
    selector: '[data-toggle="tooltip"]'
});

You can then set the property on individual elements using data attributes.

I've posted longer answer here: https://stackoverflow.com/a/20877657/207661

TL;DR: You need only one line of code that runs in document ready event:

$(document.body).tooltip({ selector: "[title]" });

Other more complicated code suggested in other answers don't seem necessary (I've tested this with Bootstrap 3.0).

I found a combination of these answers gave me the best outcome - allowing me to still position the tooltip and attach it to the relevant container:

$('body').on('mouseenter', '[rel=tooltip]', function(){
  var el = $(this);
  if (el.data('tooltip') === undefined) {
    el.tooltip({
      placement: el.data("placement") || "top",
      container: el.data("container") || false
    });
  }
  el.tooltip('show');
});

$('body').on('mouseleave', '[rel=tooltip]', function(){
  $(this).tooltip('hide');
});

Relevant HTML:

<button rel="tooltip" class="btn" data-placement="bottom" data-container=".some-parent" title="Show Tooltip">
    <i class="icon-some-icon"></i>
</button>

For me, this js reproduces the same problem that happens with Paola

My solution:

$(document.body).tooltip({selector: '[title]'})
.on('click mouseenter mouseleave','[title]', function(ev) {
    $(this).tooltip('mouseenter' === ev.type? 'show': 'hide');
});

For me, only catching the mouseenter event was a bit buggy, and the tooltip was not showing/hiding properly. I had to write this, and it is now working perfectly:

$(document).on('mouseenter','[rel=tooltip]', function(){
    $(this).tooltip('show');
});

$(document).on('mouseleave','[rel=tooltip]', function(){
    $(this).tooltip('hide');
});

Try this one: 

$('body').tooltip({
    selector: '[rel=tooltip]'
});
