请问怎样写Checkbase才能检查如果有其中一个选了就返回1
没有一个选了的返回2
[解决办法]
<script>
function Checkbase(){
var boxs = document.frm.checkbox;//这你自己改
for (i = 0;i < boxs.length;i ++){
if (boxs[i].checked){
alert( '1 ');
break;
}
}
alert( '2 ');
}
</script>
[解决办法]
for (elm in boxs)
{
if (elm.checked)
{
return;
}
}
反了吧老大~？
checked了就return;~?
