jQuery -> check the visibility of an element
<p>I have a div element which will be shown/hidden in many places.
Is it possible if I do a </p>

<pre><code>$("#divtobetracked").hide();
</code></pre>

<p>or a </p>

<pre><code>$("#divtobetracked").show();
</code></pre>

<p>that another action is fired?
Because if .hide() of the element, a button should also be hidden, and if the element wil be shown, a button should also be displayed.</p>

<p>So, I think I can write a function which toggle and do the things I want and I call the function if I want to show/hide the element.</p>

<p>But, is there another possibility, sth. like a .live() event?</p>

<p>Best Regards.</p>
