<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<SCRIPT LANGUAGE="javascript">
function check(f)
{
if (document.ok.arrive.value=="") {alert('请指定搜索条件');return false}
f.Submit.disabled =true;
return true;
}
</script>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<form name="form1" method="post" action="b.asp" onsubmit="check(this)">
<input type="radio" name="arrive" value="" style="border-style:none" onKeyDown="if(event.keyCode==13)event.keyCode=9">不限定
<input type="radio" name="arrive" value="yes" style="border-style:none" onKeyDown="if(event.keyCode==13)event.keyCode=9">已到达
<input type="radio" name="arrive" value="no" style="border-style:none" onKeyDown="if(event.keyCode==13)event.keyCode=9">未到达
<input type="submit" name="Submit" value="Submit">
</form>
</body>
</html>
搜索时的客户端判断是否已选择
我用下拉列表时候，如果没有选那么会提示
但是现在用单选框就不行了？？？？？？？
