以下代码可以实现静态网页的账号密码登录
<form method="post" action="***" name="form" onsubmit="checkpost()">
<label for="name">用户名：</label>
<input type="text" name="name" id="name" />
<br />
<label for="pw">密码：</label>
<input type="password" name="pw" id="pw" />
<br />
<input type="submit" value="提交" />
</form>
<script>
function checkpost(){
if(document.forms[5].name.value=="用户名"&&document.forms[5].pw.value==" 密码"){
window.location="跳转的地址"
}else{
alert("用户名或密码不正确！")
return false
}
}
</script>
