Usefull Javascript functions

Working on some stuff over the last few days I had to dig up all my javascript knowledge since I had to do something in simple javascript and html.

The reason I had to dig things up is because over the last couple of years every time I had a need in doing something the path I would follow would be PHP. I would write a script and more often than not I would be finished with it in a matter of minutes. Well since I wasn’t able to use PHP here I had to look into another way of doing what I wanted.

Below I will explain some function I’ve used, how you use them and why.

Please note that this might not be the best way to solve these problems, but it is the way I solved them. If you have something to say use the comments.
