Javascript scrolling text

Question

I am currently using some javascript to scroll some text on my web page. Here is the link: http://javascript.about.com/library/bltick2.htm - (I tried pasting the code into this message, but had some difficulty with it).

This line of code sets the width: var tWidth='300px';

My question is this: How can I set this to be the size of the browser window... basically to set the text to scroll from one side of the page to another?

thanks

Answer 1

var tWidth = window.innerWidth + 'px';

Or

var tWidth = '100%';
