Controlling the
<EMBED>
and
<OBJECT>
tags with JavaScript is a time-consuming
and sometimes frustrating experience. All the major companies have shipped video player
plug-ins for some time. Nevertheless, there is still no standardized set of properties and
methods that can be called up from JavaScript. A work-around solution can be manufac-
tured, but it requires extra JavaScript code to be written to wrap the plug-in APIs so that
they behave consistently with one another.
Coding an
<EMBED>
tag nested inside the error handling of an
<OBJECT>
tag is a
neat HTML trick. It will allow the browser to failover to the
<EMBED>
if the page is loaded
into a browser that does not support ActiveX
<OBJECT>
embedding.
Below is an example that will play a QuickTime movie through an ActiveX plug-in
in MSIE on Windows but that on all other browsers will play via the
<EMBED>
tag.
<OBJECT WIDTH=”120”
HEIGHT=”100”
CLASSID=”clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B”
CODEBASE=”http://www.apple.com/qtactivex/qtplugin.cab”>
<PARAM NAME=”src” VALUE=”MyMovie.mov”>
<PARAM NAME=”autoplay” VALUE=”true”>
<EMBED WIDTH=”120”
HEIGHT=”100”
SRC=”MyMovie.mov”
TYPE=”video/quicktime”
PLUGINSPAGE=”http://www.apple.com/quicktime/download/”>
</OBJECT>
More information on these techniques and some utilities is available at a number of
third-party web sites.
