when I open the HTML page like follow:

<script language="JavaScript">
alert(document.StormPlayer.src);
</Script>
the warning message will show "undefined". why?
Because not every HTML attribute has a corresponding JavaScript
property.
But alert(document.getElementById("StormPlayer").getAttribute("src"))
should work.
can I add the "src" attribute to "object" tag and can be modified by
JavaScript？
Yes, by calling objectElement.setAttribute("src", newSourceValue).
