Hi, I'm in a computer literacy class and um, I don't know much about javascript. It's confusing to me and my TA was not very helpful. I'm a beginner when it comes to computers.

Anyway, so we had an assignment where we had to make our own web page. Now the next assignment is to write a javascript program of my choice and add it to the web page. Can someone pleaaase write one for me? I guess it can just say "Welcome to my page. Hope you enjoy it"

Well Google turns up a lot if you care to look.

http://www.javascrip...rn/contents.htm Tutorial
http://homepage.ntlw...irstscript.html A very simple script.
http://www.codeproje.../jsbeginner.asp another Tutorial

And the list goes on...

A very simple script broken down.

document.write("Hello World");

document is an object. Anything you see on the page can be accessed as an object some how.

write() is a function, it does some action. In this case write something to a page.

"Hello World" is a string argument. It tells the function want to do, in the case write hello world. This can be a number, string or true or false or a variable.

An example of using a variable would be

var string = "Hello World";
document.write(string);
