<div><h2>Overview</h2>
|
|
|
|
<p>This page explains the Angular initialization process and how you can manually initialize Angular
|
|
if necessary.</p>
|
|
|
|
<h2>Angular <code><script></code> Tag</h2>
|
|
|
|
<p>This example shows the recommended path for integrating Angular with what we call automatic
|
|
initialization.</p>

<pre class="prettyprint linenums">
|
|
<!doctype html>
|
|
<html xmlns:ng="http://angularjs.org" ng-app>
|
|
<body>
|
|
...
|
|
<script src="angular.js">
|
|
</body>
|
|
</html>
|
|
</pre>
|
|
|
|
<ul>
|
|
<li>Place the <code>script</code> tag at the bottom of the page. Placing script tags at the end of the page
|
|
improves app load time because the HTML loading is not blocked by loading of the <code>angular.js</code>
|
|
script. You can get the latest bits from <a href="http://code.angularjs.org">http://code.angularjs.org</a>. Please don't link
|
|
your production code to this URL, as it will expose a security hole on your site. For
|
|
experimental development linking to our site is fine.
|
|
<ul><li>Choose: <code>angular-[version].js</code> for a human-readable file, suitable for development and
|
|
debugging.</li>
|
|
<li>Choose: <code>angular-[version].min.js</code> for a compressed and obfuscated file, suitable for use in
|
|
production.</li></ul></li>
|
|
<li><p>Place <code>ng-app</code> to the root of your application, typically on the <code><html></code> tag if you want
|
|
angular to auto-bootstrap your application.</p>
|
|
|
|
<pre><code><html ng-app>
|
|
</code></pre></li>
|
|
<li><p>If you choose to use the old style directive syntax <code>ng:</code> then include xml-namespace in <code>html</code>
|
|
to make IE happy. (This is here for historical reasons, and we no longer recommend use of
|
|
<code>ng:</code>.)</p>

</ul>

|
<h2>Automatic Initialization</h2>
|
|
|
|
<p>Angular initializes automatically upon <code>DOMContentLoaded</code> event, at which point Angular looks for
|
|
the <a href="api/ng.directive:ngApp"><code><code>ng-app</code></code></a> directive which
|
|
designates your application root. If the <a href="api/ng.directive:ngApp"><code><code>ng-app</code></code></a> directive is found then Angular
|
|
will:</p>
|
|
|
|
<ul>
|
|
<li>load the <a href="guide/module">module</a> associated with the directive.</li>
|
|
<li>create the application <a href="api/AUTO.$injector"><code>injector</code></a></li>
|
|
<li>compile the DOM treating the <a href="api/ng.directive:ngApp"><code><code>ng-app</code></code></a> directive as the root of the compilation. This allows you to tell it to treat only a
|
|
portion of the DOM as an Angular application.</li>
|
|
</ul>
|
|
|
|
<pre class="prettyprint linenums">
|
|
<!doctype html>
|
|
<html ng-app="optionalModuleName">
|
|
<body>
|
|
I can add: {{ 1+2 }}.
|
|
<script src="angular.js"></script>
|
|
</body>
|
|
</html>
|
|
</pre>
|
|
|
|
<h2>Manual Initialization</h2>
|
|
|
|
<p>If you need to have more control over the initialization process, you can use a manual
|
|
bootstrapping method instead. Examples of when you'd need to do this include using script loaders
|
|
or the need to perform an operation before Angular compiles a page.</p>
|
|
|
|
<p>Here is an example of manually initializing Angular. The example is equivalent to using the <a href="api/ng.directive:ngApp"><code>ng-app</code></a> directive.</p>
|
|
|
|
<pre class="prettyprint linenums">
|
|
<!doctype html>
|
|
<html xmlns:ng="http://angularjs.org">
|
|
<body>
|
|
Hello {{'World'}}!
|
|
<script src="http://code.angularjs.org/angular.js"></script>
|
|
<script>
|
|
angular.element(document).ready(function() {
|
|
angular.bootstrap(document);
|
|
});
|
|
</script>
|
|
</body>
|
|
</html>
|
|
</pre>
|
|
|
|
<p>This is the sequence that your code should follow:</p>
|
|
|
|
<ol>
|
|
<li><p>After the page and all of the code is loaded, find the root of the HTML template, which is
|
|
typically the root of the document.</p></li>
|
|
<li><p>Call <a href="api/angular.bootstrap"><code>api/angular.bootstrap</code></a> to <a href="guide/compiler">compile</a> the template into an
|
|
executable, bi-directionally bound application.</p></li>
|
|
</ol></div>
