Do you have to disable JavaScript, sometimes known as JScript, for some reason? Here are the step-by-step instructions for majority of the browsers. By the way, Java and JavaScript are two different things, so make sure that you're looking at the correct language.
TIP:If you're adding JavaScript to your pages, it's a good idea to view your pages with JavaScript disabled, so you can get an idea what users without JavaScript enabled browsers would see.

WARNING:Please note that you may loose some of the web page functionality by disabling JavaScript.
