Re: checkbox list ,requried field validator
sir, I use something like this, and I find it very useful especially when getting IDs from a database
here it is f you like
HTML Code:
<html>
<head>
<script type="text/javascript">
function checkIfSelected(lastone)
{
var boxes = "box" + 0;
var isChecked = false;
for (var i = 1; i <= lastone; i++){
boxes = "box" + i;
if (document.getElementById(boxes)){
if (document.getElementById(boxes).checked == true){
isChecked = true;
}
}
}
if (isChecked == false){
window.alert('check at least one please');
}
}
</script>
</head>
<body>
<form>
<input type="checkbox" id="box1" />
<input type="checkbox" id="box2" />
<input type="checkbox" id="box3" />
<input type="button" onclick="checkIfSelected(3);" value="check" />
</form>
</body>
</html>

Re: checkbox list ,requried field validator
do you just need to check if both conditions are met? I'm not sure I understand what you're asking for.
Code:
if(checkedControls.length > 0 && selected == 0){
// do something
}else{
alert("You must selected at least one checkbox");
}
