What is document.poppedLayer in javascript?
<pre><code>if (browserType == "gecko" )
document.poppedLayer =
eval('document.getElementById("realtooltip")');
else if (browserType == "ie")
document.poppedLayer =
eval('document.getElementById("realtooltip")');
else
document.poppedLayer =
eval('document.layers["realtooltip"]');
document.poppedLayer.style.visibility = "hidden";
</code></pre>

<p>poppedLayer is used in above code, I want to understand what is poppedLayer? If someone can give me reference of the documentation about it.</p>
