I want to get height of an element with JavaScript, but I want the value even if it is applied in a <style> tag, not just inline.
   <style>
     #test{height:100px;}
   </style>
   <div id="test"></div>
   <script>
   alert(document.getElementById("test").style.height);
   <script>
The above alert doesn't show anything because it just gets the inline style, not the entire style.  How can I get to access to all the styles of an element?
