关于密码判断的小问题，大家看看哪个地方有错误
在输入密码时，“密码”和“确认密码”不管相不相同，都提示“考生的密码两次输入不一致!”，大家看一下是哪个地方的毛病，代码如下：
<!--#include file= "NS_Conn.asp "-->
<!--#include file= "NS_Exam_checkuser.asp "-->

[解决办法]
楼主最好用document。
我以前也遇到。改了就行了。
[解决办法]
在前面都要加上Document.
例如:
Document.myform.zkz.value== " "
[解决办法]
不是Document,是document,看得出来LZ把两个值都输出来看过（在对话框中），相信看到的是一样的吧？如果真的这样，可以再加个document试试，如果还不行，可以return checkform( 'cnwy ')改成这个看看。
[解决办法]
if(myform.psw.value!=myform.psw1.value); 把;号去掉却可.
[解决办法]
if ()后不要跟;号 ;号代表语句结束.
因此等于永远会执行以下语句:
{
alert( "考生的密码两次输入不一致! "+myform.psw.value+ "\n "+myform.psw1.value);
myform.psw.focus();
return false;
}
[解决办法]
楼上的正解啊!
