title: When does a body onLoad gets called?
body: <p>I need to understand when does a body's <code>onload</code> gets called</p>
  
  <p>I read in <a href="http://www.w3schools.com/tags/tag_body.asp" rel="noreferrer">w3school</a> that <code>onload=Script to be run when a document load</code> what does this mean?</p>
  
  <p>Does it mean that </p>
  
  <ol>
  <li>the html/jsp page gets loaded before rendering any elements in the body like any <code>table</code> or    jsp scriplets eg: <code>&lt;%= request.getParameter("NAME") %&gt;</code></li>
  <li>Or is it after the page/body is rendered?</li>
  </ol>
  
  <p>for example:
  I have a bunch of params <code>(&lt;%= request.getParameter("NAME") %&gt;,...)</code> so in order to use them i'll place them in some hidden form item &amp; then on body load can I use them?</p>
