I have a java script that continously flashes the Back Ground. I would like to know how you would go about re-writing it so it will stop flashing the back ground after a short period of time, say, 5 seconds or so?

Here is the code:

Code:
<SCRIPT LANGUAGE="JavaScript">
var pos = 10;
function initArray() {
this.length = initArray.arguments.length;
for (var i = 0; i < this.length; i++) {
this[i] = initArray.arguments[i];
   }
}
var col=new initArray("4b","5b","8b","8b");
function stop() {
document.bgColor = '#FFFFFF';
clearTimeout(loopID);
}
function start() {
col[1]="red"
col[2]="yellowgreen"
col[3]="yellow"
col[4]="whitesmoke"
col[5]="white"
col[6]="wheat"
col[7]="violet"
col[8]="turquoise"
col[9]="tomato"
col[10]="thistle"
pos++;
if (pos<0||pos>10) {
pos = 0;
}
document.bgColor = col[pos];
loopID = setTimeout("start()",1000);
}

</SCRIPT>
Any takers?
