Disable submit button after one click in angularJS
<p>I would like to disable button after one click.</p>

<p>Code:</p>

<pre><code>&lt;button id="submitRequest" class="btn btn-primary btn-active"
        ng-disabled="!frmRequest.$valid||!r.DataUseAgreement||(!chkBMT&amp;&amp;!chkOncore&amp;&amp;!chkCAISIS&amp;&amp;!chkLIMS&amp;&amp;!chkFCR)"
        ng-click="SaveData()"&gt;
  &lt;i class="fa fa-save"&gt;&lt;/i&gt; Submit
&lt;/button&gt;
</code></pre>

<p>How to disable this one after one click?</p>

<p>Thanks!</p>
