How to use a variable as a value for attribute and setAttribute properties?

[napTaurf]

I'm trying to use setAttribute to change the link in an iframe.I want to get the link to change every few minutes to a new website chosen from an array.Everything seems to work except for one thing; I can't figure out how to get setAttribute to accept a variable or array as a link. For an example, my code looks something like this:\[code\]var linkList = [ 'link1', 'link2', 'link3'];function changePage() {for (i=0; i<4; i++) {document.getElementById('iframe').src = http://stackoverflow.com/questions/10468582/linkList;}}var timeoutNow = setTimeout("changePage()", 3000)\[/code\]The linkList part is the part I'm having trouble with - how do I get the src attribute to be set to a link stored in a variable or array?Thank you for any help you can provide.
