[webkit-dev] How to detect the parameters in object tag?

[naixuan guan]

Hi, everyone

Recently, I met a HTML page which has a object tag like this:

<OBJECT id=player style="LEFT: 0px; WIDTH:100%; TOP: 0px; HEIGHT:100%"
codebase= classid=>
    <param name="URL" value="?">
    <PARAM NAME="ShowUI" VALUE="1">
    <PARAM NAME="volume" VALUE="90">
    <PARAM NAME="autoPlay" VALUE="2">
    <PARAM NAME="mute" VALUE="0">
    <PARAM NAME="DropEnable" VALUE="0">
    <PARAM NAME="EnableFullScreen" VALUE="0">
    <PARAM NAME="ShowVideo" VALUE="1">
    <param name="loop" value="2"/>
</OBJECT>
<script language="JavaScript">
document.player.URL = urlpath+file;
</Script>

I have two questions
1.how to detect the parameters in object tag?
2.specially, how to detect the "URL" param which is changed by Javascript?

Thank you!
