<h2>Things to notice</h2>
|
|
<p>Take a look through the source and note:</p>
|
|
<ul>
|
|
<li>The script tag that <a href="guide/bootstrap">bootstraps</a> the Angular environment.</li>
|
|
<li>The text <a href="api/ng.directive:input"><code>input form control</code></a> which is
|
|
bound to the greeting name text.</li>
|
|
<li>There is no need for listener registration and event firing on change events.</li>
|
|
<li>The implicit presence of the <code>name</code> variable which is in the root <a href="api/ng.$rootScope.Scope"><code>scope</code></a>.</li>
|
|
<li>The double curly brace <code>{{markup}}</code>, which binds the name variable to the greeting text.</li>
|
|
<li>The concept of <a href="guide/dev_guide.templates.databinding">data binding</a>, which reflects any
|
|
changes to the
|
|
input field in the greeting text.</li>
|
|
</ul>
