Question: Can JavaScript code determine whether Java is enabled?
Answer:
Yes. To do so, use the navigator.javaEnabled() method.
This method is supported in all major browsers
(Internet Explorer, Firefox, Opera, Safari, Google Chrome).
Here's an example:
var javaOK = navigator.javaEnabled();
if (javaOK) document.write(''
+ 'Java is enabled: \n'
+ 'javaEnabled() returned '
+ javaOK.toString().bold()
)
else document.write(''
+ 'Java is NOT enabled: \n'
+ 'javaEnabled() returned '
+ javaOK.toString().bold()
)
In your browser, this code produces the following result:
