Loops and break statements.

I need to write a loop that adds numbers from users...but need to offer a chance to get out of the program with a break statement. Any ideas?

You said it: break

for(........){
if(condition){break}
}

But you may also use a while loop (in your case):

Code:

<head>
<title>Untitled Document</title>

<script type="text/javascript">
onload = function(){
var conf=true;
var num='';
while(conf){
num=num+prompt('Enter a number','')+' | '
var conf=confirm('Continue!')
}
document.getElementById('mydiv').innerHTML=num
}
</script>
</head>
<body>
<div id="mydiv"></div>
</body>
</html>
