How to implement login function in layui

1. The file structure of the layui framework is as follows:

How to implement login function in layui

Usage of the built-in method config

can be used Before the module, configure some parameters globally, as follows:

layui.config(
{
    dir : &#39;/res/layui/&#39; //layui.js 所在路径（注意，如果是script单独引入layui.js，无需设定该参数。），一般情况下可以无视
,
    version : false //一般用于更新模块缓存，默认不开启。设为true即让浏览器不缓存。也可以设为一个固定的值，如：201610
,
    debug : false //用于开启调试模式，默认false，如果设为true，则JS模块的节点会保留在页面
,
    base : &#39;&#39; //设定扩展的Layui模块的所在目录，一般用于外部模块扩展
}
);
//这里我主要来理解下base参数，当我自定义了一个模块，如user.js，放在/static/js/目录下，即不是layui里有的，那么我可以通过如下方法使用自定义模块里的方法：
layui.config(
{
    base : "/static/js/"
}
).use([&#39;user&#39;], function ()
{
    var user = layui.user;
    user.findUsrByUserName(username);
}
);
]

Implementation of login page

(1) Log in, I mainly used layui’s carousel and submission functions, the language is too pale, Directly paste the code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <meta charset="UTF-8" />
  <title>登录</title>
  <link rel="stylesheet" href="/resource/plugins/layui/css/layui.css" type="text/css" />
  <link rel="stylesheet" href="/resource/css/login.css" type="text/css" />
  <script type="text/javascript" src="/resource/plugins/layui/layui.js">
</script>
</head>
<body>
  <div class="layui-carousel video_mask" id="login_carousel">
    <div carousel-item="">
      <div class="carousel_div1"></div>

      <div class="carousel_div2"></div>

      <div class="carousel_div3"></div>

      <div class="carousel_div4"></div>

      <div class="carousel_div5"></div>
    </div>

    <div class="login layui-anim layui-anim-up">
      <h1>登录</h1>

      <form class="layui-form" action="" method="post">
        <div class="layui-form-item">
          <input type="text" name="username" lay-verify="required" placeholder="请输入用户名" autocomplete="off" value="" class="layui-input" />
        </div>

        <div class="layui-form-item">
          <input type="password" name="password" lay-verify="required" placeholder="请输入密码" autocomplete="off" value="" class="layui-input" />
        </div><button class="layui-btn layui-btn-normal login_btn" lay-submit="" lay-filter="login">登陆系统</button>
      </form>
    </div>
  </div>
</body>
</html>![输入图片说明](https://static.oschina.net/uploads/img/201709/03092118_VUPK.png "在这里输入图片标题")
