在做项目的过程中，我们时常需要进行一些弹框操作，比如在后台管理时需要进行的一些增删改操作，这个时候我们需要使用到弹框，或者在网站浏览时进行弹框输入，博主也曾经在开发时使用一个个页面的方式，但那样的前端效果不太美观，今天，闲来无事，分享给大家自己写的一个前端的弹框demo，话不多说，直接上图：
以下是相关代码：
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link href="css/index.css" rel="stylesheet" type="text/css">
<script src="js/index.js"></script>
</head>
<body>
<div class="main">
<button id="btn_1"> 弹 框 输 入</button>
<div class="form_1">
<form >
<div class="input_1"><div class="login_logo">用户登录</div><div class="close">X</div></div>
<hr>
<div class="input_1"><input type="text" name="user" placeholder=" 用户名"></div>
<div class="input_1"><input type="password" name="password" placeholder=" 密码"></div>
<div class="input_1"><input class="submit_1" type="submit" value="提 交"></div>
</form>
</div>
</div>
<div class="test"><h1>弹框登录，输入文字，可开发与后台交互，直接用</h1></div>
<button id="btn_2"> 弹 框 提 示</button>
<div class="dialog">
<div class="title">恭喜：操作成功 !</div>
<div class="btn_2">确定</div>
<div class="close_1">取消</div>
</div>
<div class="test"><h1>弹框提示，自行修改提示内容即可</h1></div>
</body>
</html>
