在 AngularJS 中使用 Bootstrap 工具提示

Have you included the Bootstrap JS and jQuery?

<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.0.2/js/bootstrap.min.js"></script>

If you don't already load those, then Angular UI (http://angular-ui.github.io/bootstrap/) may not be much overhead. I use that with my Angular app, and it has a Tooltip directive. Try using tooltip="tiptext"

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

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!

If you're building an Angular app, you can use jQuery, but there is a lot of good reasons to try to avoid it in favor of more angular driven paradigms. You can continue to use the styles provided by bootstrap, but replace the jQuery plugins with native angular by using UI Bootstrap

Include the Boostrap CSS files, Angular.js, and ui.Bootstrap.js:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://code.angularjs.org/1.2.20/angular.js"></script>
<script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.11.0.js"></script>

Make sure you've injected ui.bootstrap when you create your module like this:

var app = angular.module('plunker', ['ui.bootstrap']);

Then you can use angular directives instead of data attributes picked up by jQuery:

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

Demo in Plunker

Avoiding UI Bootstrap

jQuery.min.js (94kb) + Bootstrap.min.js (32kb) is also giving you more than you need, and much more than ui-bootstrap.min.js (41kb).

And time spent downloading the modules is only one aspect of performance.

If you really wanted to only load the modules you needed, you can "Create a Build" and choose tooltips from the Bootstrap-UI website. Or you can explore the source code for tooltips and pick out what you need.

Here a minified custom build with just the tooltips and templates (6kb)

You can do this with AngularStrap which

is a set of native directives that enables seamless integration of Bootstrap 3.0+ into your AngularJS 1.2+ app."

You can inject the entire library like this:

var app = angular.module('MyApp', ['mgcrea.ngStrap']);

Or only pull in the tooltip feature like this:

var app = angular.module('MyApp', ['mgcrea.ngStrap.tooltip']);

Demo in Stack Snippets

var app = angular.module('MyApp', ['mgcrea.ngStrap']);

<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.15/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular-strap/2.1.2/angular-strap.min.js"></script>

<div ng-app="MyApp" class="container" >


<button type="button"
class="btn btn-default"
data-trigger="hover"
data-placement="right"
data-title="Tooltip on right"
bs-tooltip>
MyButton
</button>


</div>

The best solution I've been able to come up with is to include an "onmouseenter" attribute on your element like this:

<button type="button" class="btn btn-default"
data-placement="left"
title="Tooltip on left"
onmouseenter="$(this).tooltip('show')">
</button>

AngularStrap doesn't work in IE8 with angularjs version 1.2.9 so not use this if your application needs to support IE8

easiest way , add $("[data-toggle=tooltip]").tooltip(); to the concerned controller.

I wrote a simple Angular Directive that's been working well for us.

Here's a demo: http://jsbin.com/tesido/edit?html,js,output

Directive (for Bootstrap 3):

// registers native Twitter Bootstrap 3 tooltips
app.directive('bootstrapTooltip', function() {
return function(scope, element, attrs) {
attrs.$observe('title',function(title){
// Destroy any existing tooltips (otherwise new ones won't get initialized)
element.tooltip('destroy');
// Only initialize the tooltip if there's text (prevents empty tooltips)
if (jQuery.trim(title)) element.tooltip();
})
element.on('$destroy', function() {
element.tooltip('destroy');
delete attrs.$$observers['title'];
});
}
});

Note: If you're using Bootstrap 4, on lines 6 & 11 above you'll need to replace tooltip('destroy') with tooltip('dispose') (Thanks to user1191559 for this upadate)

Simply add bootstrap-tooltip as an attribute to any element with a title. Angular will monitor for changes to the title but otherwise pass the tooltip handling over to Bootstrap.

This also allows you to use any of the native Bootstrap Tooltip Options as data- attributes in the normal Bootstrap way.

Markup:

<div bootstrap-tooltip data-placement="left" title="Tooltip on left">
Tooltip on left
</div>

Clearly this doesn't have all the elaborate bindings & advanced integration that AngularStrap and UI Bootstrap offer, but it's a good solution if you're already using Bootstrap's JS in your Angular app and you just need a basic tooltip bridge across your entire app without modifying controllers or managing mouse events.

You can use selector option for dynamic single page applications:

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

if a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have tooltips added.

You can create a simple directive like this:

angular.module('myApp',[])
.directive('myTooltip', function(){
return {
restrict: 'A',
link: function(scope, element){
element.tooltip();
}
}
});

Then, add your custom directive where is necessary:

<button my-tooltip></button>

Simple Answer - using UI Bootstrap (ui.bootstrap.tooltip)

There seem to be a bunch of very complex answers to this question. Here's what worked for me.

1. Install UI Bootstrap - $ bower install angular-bootstrap

2. Inject UI Bootstrap as a dependency - angular.module('myModule', ['ui.bootstrap']);

3. Use the uib-tooltip directive in your html.

<button class="btn btn-default"
type="button"
uib-tooltip="I'm a tooltip!">
I'm a button!
</button>

Please remember one thing if you want to use bootstrap tooltip in angularjs is order of your scripts if you are using jquery-ui as well, it should be:

• jQuery
• jQuery UI
• Bootstap

It is tried and tested

impproving @aStewartDesign answer:

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

There's no need for jquery, its a late anwser but I figured since is the top voted one, I should point out this.

Only read this if you are assigning tooltips dynamically

i.e. <div tooltip=\{\{ obj.somePropertyThatMayChange }} ...></div>

I had an issue with dynamic tooltips that were not always updating with the view. For example, I was doing something like this:

This didn't work consistently

<div ng-repeat="person in people">
<span data-toggle="tooltip" data-placement="top" title="\{\{ person.tooltip }}">
\{\{ person.name }}
</span>
</div>

And activating it as so:

$timeout(function() {
$(document).tooltip({ selector: '[data-toggle="tooltip"]'});
}, 1500)

However, as my people array would change my tooltips wouldn't always update. I tried every fix in this thread and others with no luck. The glitch seemed to only be happening around 5% of the time, and was nearly impossible to repeat.

Unfortunately, these tooltips are mission critical for my project, and showing an incorrect tooltip could be very bad.

What seemed to be the issue

Bootstrap was copying the value of the title property to a new attribute, data-original-title and removing the title property (sometimes) when I would activate the toooltips. However, when my title=\{\{ person.tooltip }} would change the new value would not always be updated into the property data-original-title. I tried deactivating the tooltips and reactivating them, destroying them, binding to this property directly... everything. However each of these either didn't work or created new issues; such as the title and data-original-title attributes both being removed and un-bound from my object.

What did work

Perhaps the most ugly code I've ever pushed, but it solved this small but substantial problem for me. I run this code each time the tooltip is update with new data:

$timeout(function() {
$('[data-toggle="tooltip"]').each(function(index) {
// sometimes the title is blank for no apparent reason. don't override in these cases.
if ($(this).attr("title").length > 0) {
$( this ).attr("data-original-title", $(this).attr("title"));
}
});
$timeout(function() {
// finally, activate the tooltips
$(document).tooltip({ selector: '[data-toggle="tooltip"]'});
}, 500);
}, 1500);

What's happening here in essence is:

• Wait some time (1500 ms) for the digest cycle to complete, and the titles to be updated.
• If there's a title property that is not empty (i.e. it has changed), copy it to the data-original-title property so it will be picked up by Bootstrap's toolips.
• Reactivate the tooltips

Hope this long answer helps someone who may have been struggling as I was.

install the dependencies:

npm install jquery --save
npm install tether --save
npm install bootstrap@version --save;

next, add scripts in your angular-cli.json

"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js",
"script.js"
]

then, create a script.js

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

now restart your server.

Try the Tooltip (ui.bootstrap.tooltip). See Angular directives for Bootstrap

<button type="button" class="btn btn-default" tooltip-placement="bottom" uib-tooltip="tooltip message">Test</button>

It is recommended to avoid JavaScript code on the top of AngularJS

for getting tooltips to refresh when the model changes, i simply use data-original-title instead of title.

e.g.

<i class="fa fa-gift" data-toggle="tooltip" data-html="true" data-original-title=\{\{getGiftMessage(gift)}} ></i>

note that i'm initializing use of tooltips like this:

<script type="text/javascript">
$(function () {
$("body").tooltip({ selector: '[data-toggle=tooltip]' });
})
</script>

versions:

• AngularJS 1.4.10
• bootstrap 3.1.1
• jquery: 1.11.0

Because of the tooltip function, you have to tell angularJS that you are using jQuery.

This is your directive:

myApp.directive('tooltip', function () {
return {
restrict: 'A',
link: function (scope, element, attrs) {
element.on('mouseenter', function () {
jQuery.noConflict();
(function ($) {
$(element[0]).tooltip('show');
})(jQuery);
});
}
};
});

and this is how to use the directive :

<a href="#" title="ToolTip!" data-toggle="tooltip" tooltip></a>
