<script>
function check(){
if(Len(CStr(form1.input1.value))<6)
{alert("名字必须大于6！");
return false;}
return true;
}
</script>
<form onsubmit="return check()" action="qqqqqq.asp" method="POST" name=form1>
<input type="text" name="input1" size="20"><input type="submit" value="提交" name="B1"></form>
function check(){
if(Len(CStr(form1.input1.value))<6)
{alert("名字必须大于6！");
return false;}
return true;
}
</script>
<form onsubmit="return check()" action="qqqqqq.asp" method="POST" name=form1>
<input type="text" name="input1" size="20"><input type="submit" value="提交" name="B1"></form>
<script>
function check(){
if(form1.input1.value.length<6)
{alert("名字必须大于6！");
return false;}
form1.submit
}
</script>
<form onsubmit="return check()" action="qqqqqq.asp" method="POST" name=form1>
<input type="text" name="input1" size="20"><input type="submit" value="提交" name="B1"></form>这样写就可以提交了
它的测试长度不是那个方法，而是放后面length
调试已经正确，分数拿来哈哈
