Is it possible to change the file path of the vide

问题:

I have an object tag in a HTML file:

<object classid="clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95">
     <param name="FileName" value="../ABC/WildLife.wmv" id="mediaPlayerFile">
     <param name="AutoStart" value="false" />
</object>

I want to change the filename using javascript.

What I have so far is this:

<script type="text/javascript">
    function disp_current_directory() {
        var val = document.getElementById('mediaPlayerFile');
        val.attributes['value'].value = "D:\XYZ\WildLife.wmv";
    }

</script>

But this doesn't work. :(

Is it possible? If yes, how?

回答1:

You cannot do this after the object has been initialized as the parameters supplied using <param..> are only used during object creation.

To update this you will have to replace the entire object tag with new parameters.

If you want to access the api of the object, take a look at this question Is there a documented JavaScript API for Windows Media Player?
