Testing if Quicktime and Java are installed?

Question

In Javascript how can I test if the user has the quicktime plugin and java plugins installed?

Answer 1

For Java, you can use navigator.javaEnabled(). Or you can look here: http://www.pinlady.net/PluginDetect/JavaDetect.htm

For QuickTime, you can do:

var QtPlugin = navigator.plugins["Quicktime"];
if (QtPlugin) {//QuickTime is installed}

See here: http://javascript.internet.com/miscellaneous/check-plugins.html

Answer 2

This of course does not work in IE. The only way to check plugins in IE is using VB script, and it is very strange and messy. You can only test for specific plugin versions, for example, "quicktime" won't cut it. You have to specify the version, which is not published for versions older than 5, and I can't find a reference for version 7.
