不能通过check的状态改变按钮是否可用
<script type="text/javascript">function sub() {
alert("dfd");
if (document.vForm.after.checked) {
document.vForm.inputSubmit.disabled = disabled;
} else {
document.vForm.inputSubmit.disabled=false;
}
}
</script> --------------------编程问答-------------------- 楼主这个问题，当时在学校的时候也遇到过，现在不知道该怎么改了 --------------------编程问答--------------------

<html>

}
document.forms["myForm"].submit();
