Useing Javascript To Change The Background?

Is there anyway to put a javascript code onto my forum that will allow users to change the background color themselfs? I really love this JS code and would love it on my forum if it's posible. Thanx!

you can use the meta tags option in your admin panel.
go to admin panel -> display -> generalities and add a new meta tag... and choose the javascript option... you will be asked for the url (src="") to the script file .

If you know your way around coding then thats the way to install it

How do I get the url for my code?

My code is:

Code:

<CENTER>
<FORM>
<SELECT name="ccGround" size="1" onChange=(document.bgColor=ccGround.options[ccGround.selectedIndex].value)>
<OPTION value="ffffff" target="1" selected> White
<OPTION value="ffcf25" target="1"> Gold
<OPTION value="aa0000" target="1"> Dark Red
<OPTION value="00aa00" target="1"> Dark Green
<OPTION value="0000aa" target="1"> Dark Blue
<OPTION value="aa00aa" target="1"> Purple
<OPTION value="00aaaa" target="1"> Dark Cyan
</SELECT>
</FORM>
</CENTER>

Do I need a new one? Or is that one fine?

Edit: I'm new to codeing so thats kinda why I need help...
