Name

CLASSID — NN 4 IE 3 HTML 4

Synopsis

CLASSID=”URL"

Optional

The URL of the object’s implementation. This attribute typically directs the browser to load program, applet, or plugin class files. In Internet Explorer, the URL can point to the CLSID directory that stores all of the IDs for registered ActiveX controls, such as DirectAnimation. You must obtain the CLASSID value from the supplier of an ActiveX control. In Navigator 4, the Java Archive (JAR) Installation Manager attempts to install a plugin from the CLASSID URL if the plugin is not installed for data specified in the DATA attribute. Eventually, this attribute may be used to load Java applets (IE 4 includes a CODE attribute to handle this now), but through Version 4 of both browsers, Java applets are not yet supported in this fashion.

Example

<OBJECT ID="earth" CLASSID="clsid:83A38BF0-B33A-A4FF-C619A82E891D">
</OBJECT>

Value

A complete or relative URL.

Default

None.
