JavaScript Support for ActiveX, Netscape 6 and Mozilla

New in QuickTime 6, the QuickTime ActiveX control for Windows is fully scriptable using JavaScript.

This means you can now use JavaScript to control QuickTime when Web pages are viewed using Internet Explorer for Windows, or any other browser that supports the COM interface to ActiveX controls.

Also new in QuickTime 6, the QuickTime browser plug-in is scriptable using the XPCOM interface supported by Netscape 6 and later and Mozilla 1.0.

This means you can now use JavaScript to control QuickTime when Web pages are viewed using Netscape 6 or later, or browsers based on Mozilla 1.0, on both Mac OS and Windows.

QuickTime is now scriptable from Web pages viewed using any browser that supports JavaScript and any of the LiveConnect, XPCOM, or COM interfaces. This includes most current browsers for Windows and Macintosh, with the notable exception of Internet Explorer for Macintosh, which does not allow scripting of plug-ins.

In summary:

• QuickTime 4.1 is scriptable using Netscape 4 or 5 on Macintosh or Windows.

• QuickTime 6 adds scriptability using most current browsers on Windows and Macintosh, including:

  • Netscape 4 and later (including Netscape 6) on Macintosh and Windows

  • Mozilla 1.0 on Macintosh and Windows

  • Internet Explorer for Windows

  • AOL 5 and later for Windows

  • MSN 6

• Plug-ins are not scriptable using Internet Explorer for Macintosh.

To control a movie through the QuickTime plug-in using JavaScript, you must include the parameter EnableJavaSript="true" in the movie’s EMBED tag (this parameter is not needed in the OBJECT tag, but it does no harm there).

JavaScript treats each embedded QuickTime movie in a Web page as a separately addressable object. Movies can be identified by name if there is a NAME parameter in the movie’s EMBED tag and an ID attribute in the movie’s OBJECT tag. Internet Explorer for Windows uses the ID attribute. Other browsers use the NAME parameter. Both NAME and ID should be set to the same value.

For example, to create a movie that can be addressed in JavaScript as "Movie1", your OBJECT and EMBED tags would look something like this:

<OBJECT classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B"

    codebase="http://www.apple.com/qtactivex/qtplugin.cab"

    width="180" height="160"

    id="movie1" >

    <PARAM name="src" value="My.mov">

    <EMBED width="180" height="160"

        src="My.mov"

        name="movie1"

        enablejavascript="true">

    </EMBED>

</OBJECT>

Movies can also be identified by their ordinal number in the JavaScript embeds[] array.

An example of usage and syntax, showing JavaScript control of multiple QuickTime movies using different methods of addressing, can be found in the “Sample JavaScript Usage” section of “What’s New in QuickTime 4.1” at:

QuickTime exposes dozens of methods to JavaScript, allowing you to control not only the standard user interface actions, such as playing and stopping a movie, but also more complex actions, such as layering and compositing. You can use JavaScript, for example, to enable and disable alternate audio, text, or video tracks, or change a video track’s graphics mode or a sprite's current image.

Detailed descriptions of the QuickTime methods and properties available to JavaScript can be found in the “JavaScript Support” section of “What’s New in QuickTime 4.1” at:

http://developer.apple.com/documentation/quicktime/REF/QT41_HTML/QT41WhatsNew-72.html

This bug is marked as fixed for the next release of Netscape and Mozilla.
