PARAM Elements in an OBJECT Element

Windows Media Player uses the PARAM element to define specific startup conditions for the control. The PARAM element is embedded inside the OBJECT element.

For example, if you want to define whether the autoStart property is True, you would embed the PARAM element inside the OBJECT element.

<OBJECT ID="Player"
    <PARAM name="autoStart" value="True">

You can have as many PARAM elements in an OBJECT element as you want. PARAM has two attributes, name and value. Both attributes must be set.

The supported PARAM attributes vary slightly among browsers and mime types. The following table shows the attributes supported by the Internet Explorer and Firefox browsers. The preferred mime type for the Firefox browser is application/x-ms-wmp, however, there are several other mime types that you can use to embed the Player control in a webpage hosted by the Firefox browser. The fourth column of the table shows the attributes that are supported when you use a mime type other than application/x-ms-wmp.

See the Object Model Reference for Scripting for more details about the values for each name attribute.
