阅读更多关于 Determine whether client browser has java installed and can launch applets

I am developing an .aspx page which will ultimately launch an applet after the user clicks on a button (I am using the <applet> tag). So, I would like to detect if java is enabled/installed on the user's browser. I am using navigator.javaEnabled() method.
