Using Bootstrap Tooltip with AngularJS

Question

I am trying to use the Bootstrap tooltip in an app of mine. My app is using AngularJS Currently, I have the following:

<button type="button" class="btn btn-default" 
        data-toggle="tooltip" data-placement="left"
        title="Tooltip on left">
            Tooltip on left
</button>

I think I need to use

$("[data-toggle=tooltip]").tooltip();

However, I'm not sure. Even when I add the line above though, my code doesn't work. I'm trying to avoid using UI bootstrap as it has more than I need. However, if I had to include just the tooltip piece, I'd be open to that. Yet, I can't figure out how to do that.

Can someone show me how to get the Bootstrap Tooltip working with AngularJS?

Answer 1

In order to get the tooltips to work in the first place, you have to initialize them in your code. Ignoring AngularJS for a second, this is how you would get the tooltips to work in jQuery:

$(document).ready(function(){
    $('[data-toggle=tooltip]').hover(function(){
        // on mouseenter
        $(this).tooltip('show');
    }, function(){
        // on mouseleave
        $(this).tooltip('hide');
    });
});

This will also work in an AngularJS app so long as it's not content rendered by Angular (eg: ng-repeat). In that case, you need to write a directive to handle this. Here's a simple directive that worked for me:

app.directive('tooltip', function(){
    return {
        restrict: 'A',
        link: function(scope, element, attrs){
            element.hover(function(){
                // on mouseenter
                element.tooltip('show');
            }, function(){
                // on mouseleave
                element.tooltip('hide');
            });
        }
    };
});

Then all you have to do is include the "tooltip" attribute on the element you want the tooltip to appear on:

<a href="#0" title="My Tooltip!" data-toggle="tooltip" data-placement="top" tooltip>My Tooltip Link</a>

Hope that helps!
