Need help for jQuery
<pre><code>&lt;body&gt;
    &lt;button&gt; Change  &lt;/button&gt;
    &lt;div id="mydiv" style="margin:25% 0% 0% 37%"&gt;
        &lt;a href="#" onclick="alert('buhaha');" style="width:50px; height:50px; background-color:#99CC99; padding:10px; margin:5px"&gt;One&lt;/a&gt;
        &lt;a href="#" onclick="alert('buhaha');" style="width:50px; height:50px; background-color: #FF9900;padding:10px; margin:5px"&gt; Two&lt;/a&gt;
    &lt;/div&gt;
&lt;/body&gt;
</code></pre>

<p>When I click my "Change" button, onclick event must disable. After I click "Change" button again, onclick event must enable. How do I do these two actions from one button?</p>

<p>I used jquery-1.4.1.min.js. Answer code must work with jquery-1.4.1.min.js file.</p>
