html可以使用表单进行的最简单的账号密码登录的页面设计,但是不具备判断账号密码正确性等逻辑的能力,这个需要后台语言处理反馈。
工具原料:编辑器、浏览器
1、使用form表单事件最简单的账号密码登录的数据提交,代码如下:
<!DOCTYPE html><html>
<body>
<form action="login.php">
用户名:<br>
<input type="text" name="firstname" value="请输入账号">
<br>
密码:<br>
<input type="text" name="lastname" value="请输入密码">
<br><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
2、点击提交数据将会提交给login.php进行处理,运行的结果如下:
<!DOCTYPE html><html lang="zh-CN"><head><meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>登录</title>
<link href="css/bootstrap.min.css" rel="stylesheet"></head><body><nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="./">jsp作业</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li><a href="login.html">登录</a></li>
</ul>
</div>
</div></nav><div class="container">
<div class="row">
<div class="col-md-4">
</div>
<div class="col-md-4">
<form class="form-signin" target="submitFrame" method="post">
<h2 class="form-signin-heading">登录到jsp作业</h2>
<label for="inputEmail">Email</label>
<input type="email" id="inputEmail" class="form-control" placeholder="请输入Email" required autofocus><br>
<label for="inputPassword">密码</label>
<input type="password" id="inputPassword" class="form-control" placeholder="请输入密码" required>
<div class="checkbox">
<label>
<input type="checkbox" value="remember-me" checked="checked">记住密码</label>
</div>
<button type="submit" class="btn btn-primary" id="btn-login">登录</button>
<a href="reg.html" class="btn btn-default">注册</a>
</form>
<iframe style="display: none" name="submitFrame" src="about:blank"></iframe>
</div>
<div class="col-md-4">
</div>
</div>
<script src="js/jquery.min.js"></script></body></html>
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>
