Javascript disabled, short questions

javascript

Solution

Sun's Java is not the same thing as JavaScript. Java is an extension to the browser which user might or not have installed. JavaScript comes with browser and can be disabled by the user.

Display a notice to the user that he/she should turn JavaScript on.

Ajax and jQuery are Javascript, so yes, they're disabled also.

Problem

Just some short Q regarding javascript and websites. 1- By javascript enabled, does it mean to have 'sun java' installed and enabled in the browser settings? Or does every browser have javascript enabled always? 2- If javascript is disabled, my website for example wouldn't work at all, so what does major developers do in these situations, if the only way to achieve their goal is to use javascript? 3- Is ajax also disabled if javascript is disabled? Also, same for Jquery because its a javascript library ? Thanks guys
