Javascript Injection

Javascript injection is when you inject a short javscript temporarly into a
webpage. It is only temporary so don't worry about getting caught or any of that
nonsense. Javascript injection is entered in the address bar throught the 
javascript protocol. the javascript protocol is Javascript:code. Here are some 
examples of common javascript injections.

***Example***
Javascript:alert(document.cookie)

This script will make a popup box come up with the contents of the cookie that 
is saved on that site. If a boc comes up with no contents at all then a cookie 
is not saved to the site.

Javascript:alert(document.forms[0].to.name)

This script will show the name of the first form on the page. Remember that the 
first form on the page is form "0" not form "1."
*************

Javascript injection can also be used to change the contents of the html, as 
follows...

***Example***
Javascript:void(document.cookie="value = string")

Replace value with the name of the string you want to alter and string with the 
result you want to change.

Javascript:void(document.forms[0].to.name="hello")

This simple script will change the name of the first form on the page to hello. 
*************

You can also have more than one script on the same line to check to see if your 
script turned out right.

***Example***
Javascript:void(forms[1].to.name="hello"); alert(forms[0].to.value)

This will check to make sure that your first script worked right.
*************

***Note***
A good example on how to use this in on http://www.hackthissite.org in the basic
missions. I think it's four or five missions into the basic missions so you will
have to complete the ones before it also.
