javascript

I know html and javascript but I dont just understand how you use it for javascript injection. Can anybody give me the name of a website that has information on that or explain it to me? That would be nice.

A good place to start is w3schools.com. Also check out all the articles here on hbh, some good ones in there and always read the forums they will help!:D

for injecting into the url its as simple as doing:

javascript: then put your code here

simple :)

yes, you can use it the way mr. cheese explained it to get past rapidshares download countdown time.
