Single Global JavaScript Object Namespace

Understanding JavaScript Hacking

Today I somehow landed on a page about JavaScript hacking. I found the article interesting so decided to search google on the subject: http://www.google.com.fj/search?q=javascript+hacking

Simple Javascript Confirm Box

I came across a question on a PHP forum about the JavaScript confirm function and how it can communicate with php.

For most it's obvious that PHP has nothing to do with this. But to be clear, JavaScript is client side, and PHP is server side. The only way they can communicate is by sending an HTTP request to the server. This tells the PHP what the JavaScript side needs or has done, and the reply from the PHP server lets the JavaScript know what the PHP has done or needs.
