Sorry to be asking so many questions, but I don't have a javascript book in front of me. If anyone knows a good link to a site that works just as well, please point me to it.
In the meantime, what is the command to repeat a piece of code X many times, where X is a user defined variable?
i know var x = 100 or however to get that working.

Hi!

That depends on what has to be done x times.

Here is an example writing the same line x times (except its'number):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled</title>
<script language="JavaScript" type="text/javascript">
<!--
var writeToDoc;
var minValue=1;//put your min. value here
var maxValue=100;//put your max. value here
function loopIt(){
writeToDoc="";
var usNum=parseInt(document.myForm.usersNumber.value);
if (!isNaN(usNum)&&usNum<=maxValue&&usNum>=minValue){
document.getElementById('resultSpan').innerText="";
for (var x = 1; x <= usNum; x++){
writeToDoc +='This is line # '+ x+'\r\n';
}
document.getElementById('resultSpan').innerText=writeToDoc;
}
else{
alert('Only numbers between '+ minValue + ' and '+maxValue+' allowed!');
return false;
}
}
//-->
</script>
</head>
<body>
<form name="myForm">Please insert a number between
<script language="JavaScript" type="text/javascript">
<!--
document.write(minValue + ' and ' + maxValue + ':');
//-->
</script>
<br>
<input type="text" name="usersNumber"><br>
<input type="button" onClick="loopIt()" value="click me">
</form>
<span id="resultSpan"></span>
</body>
</html>

Cheers - Pit

right, so
repeat:
var x = 2
for(m = 0; m < x; m++) {
}

while:
for(m = 0; m = 0; m = m) {
var m = 1
}

thank you very much.
