title: reading and modifying inline style "height" using jquery?
body: <p>In page I have below tag:</p>
  
  <pre><code>&lt;div id="main_body" class="mainbox" style="height: 769px;"&gt;
  </code></pre>
  
  <p>I can select this div using:</p>
  
  <pre><code>   var diiv= $("#main_body")
  </code></pre>
  
  <p>Can you please guide me how to read and modify the hight attribute in, inline style. I need to read this for some other calculation as well.</p>
