How to implement login function in layui
1. The file structure of the layui framework is as follows:
Usage of the built-in method config
can be used Before the module, configure some parameters globally, as follows:
layui.config(
{
dir : '/res/layui/' //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 : '' //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(['user'], 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 id="登录">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> < script type = "text/javascript" >
//<![CDATA[
layui.use(['form', 'layer', 'jquery', 'carousel'], function ()
{
var $ = layui.jquery,
form = layui.form,
carousel = layui.carousel;
/**背景图片轮播*/
carousel.render(
{
elem : '#login_carousel',
width : '100%',
height : '100%',
interval : 2000,
arrow : 'none',
anim : 'fade',
indicator : 'none'
}
);
/**监听登陆提交*/
form.on('submit(login)', function (data)
{
//弹出loading
var loginLoading = top.layer.msg('登陆中，请稍候',
{
icon : 16,
time : false,
shade : 0.8
}
);
//记录ajax请求返回值
var ajaxReturnData;
//登陆验证
$.ajax(
{
url : '/login/login',
type : 'post',
async : false,
data : data.field,
success : function (data)
{
ajaxReturnData = data;
}
}
);
//登陆成功
if (ajaxReturnData.rendercode == 0)
{
window.location.href = "/";
top.layer.close(loginLoading);
return false;
}
else
{
top.layer.close(loginLoading);
top.layer.msg(ajaxReturnData.errmsg,
{
icon : 5
}
);
return false;
}
}
);
}
);

Adaptive layout can be achieved by using the responsive layout function of the layui framework. The steps include: referencing the layui framework.

The difference between layui and Vue is mainly reflected in functions and concerns. Layui focuses on rapid development of UI elements and provides prefabricated components to simplify page construction; Vue is a full-stack framework that focuses on data binding, component development and state management, and is more suitable for building complex applications. Layui is easy to learn and suitable for quickly building pages; Vue has a steep learning curve but helps build scalable and easy-to-maintain applications. Depending on the project needs and developer skill level, the appropriate framework can be selected.
