<script type="text/javascript">
for (i=0; i<document.test.finallevelusers.length; i++){
if (document.test.finallevelusers[i].checked !=true)
document.test.finallevelusers[i].disabled='true';
}
</script>
probably you want them enabled again when user uncheck the checkbox
当用户取消选中复选框时，您可能希望它们再次启用
for (i=0; i<document.test.finallevelusers.length; i++){
if (document.test.finallevelusers[i].disabled ==true)
document.test.finallevelusers[i].disabled='false';
}

You could do
你可以做
$('input').attr('disabled',true);
...if you really need it. But you might be better off using radio buttons.
……如果你真的需要它。但是您最好使用单选按钮。

Try code like this
试试这样的代码

function uncheck(){
for(var ii=1; ii<=4; ii++){

}
