type 没指定！还有就是楼上说的拼写错误。lz再检查一下吧，没准还有地方漏了，建议用VS2005编辑，它会提示你哪些代码不合标准（虽然不符合标准有时候也可以正常工作）。
language= "JavaScript " language= "JavaScript"
注意"JavaScript"后面没有空格
其他<input type= "text " name= "password " id= "password "/>等等也是一样，你的这些对象的ID都带有一个空格，所以document.myform.password就没法找到那个元素
请注意你那些乱七八糟的空格，<form action= " " name= "myform ">， name= "myform "中带有一个空格，所以 document.myform就找不到它，用document.getElementById( "password ")【有空格】才能找到它
2.objDiv.style.diaplay= "block ";你自己检查这个错在哪儿<html>
