hi tnx for the reply ,BUT this is not what im looking for
in your case the user checks that input checkbox , i like that the user will not be ABLE to do that
not disable the checkbox ,but not let the checkbox to be checked
hope i made my seld clear here..
tnx

Is this what you need?

<html>
<head>
<script>
var allow_check=true;

function foo(){
allow_check=false;
}
</script>
</head>
<body>
<input type="checkbox" name="blah" onclick="return allow_check;" >
<input type="button" onclick="foo();" value="disable">
</body>
</html>

or simply:

<input type="checkbox" name="blah" onclick="return false">

but why not just disable it:

<input type="checkbox" name="blah" disabled>
