以下JS有什么问题呢？怎么没有错误报告也不起作用那？

<script language="javascript">
function check_notify()
{
if (document.order_post.no_notify.checked)
{
document.all.r1.disabled=false;
}else{
document.all.r1.disabled=true;
}
}
</script>
……
<form name="order_post" method="post" action="order_post.asp">
<input type="checkbox" name="no_notify" value="1" onclick="check_notify()">
<input type="radio" name="handle" id="r1" value="1" disabled="false">
<input type="radio" name="handle" id="r1" value="2" disabled="false">
<input type="radio" name="handle" id="r1" value="3" disabled="false">
<input type="radio" name="handle" id="r1" value="4" disabled="false">
</form>
