介紹
由國人開發，16年出廠的框架，其主要提供了很多好看、方便的樣式，並且基本拿來即用，和Bootstrap有些相似，但個人認爲該框架有個極大的好處就是定義了很多前後端交互的樣式接口，如分頁表格，只需在前端配置好接口，後端則按照定義好的接口規則返回數據，即可完成頁面的展示，極大減少了後端人員的開發成本。
說白了，該框架就是爲了方便後端人員開發前端而使用的。

Layui、Easyui和Bootstrap對比

個人總結（三個框架依次順序）：美且輕、強但醜、簡且穩
環境導入
// 本地導入：
<link rel="stylesheet" href="./layui/css/layui.css" media="all">
// 導入CSS文件
<script src="./layui/layui.js"></script>
// 導入JS文件
// CDN導入：
<link rel="stylesheet" href="https://www.layuicdn.com/layui-v2.5.4/css/layui.css" media="all">
<script src="https://www.layuicdn.com/layui-v2.5.4/layui.js"></script>
<!-- 該CDN引入字體會出現跨域情況，因此一些空間的樣式顯示會出現異常 -->
注：
若將Layui下載到本地進行導入時，記得在將layui.css和layui.js導入的同時，將其中的字體等也一同導入，以免顯示的結果有異常
使用CDN導入時，提供的CDN鏈接由於配置文件，在導入字體文件等時會出現跨域請求的問題，所以字體等可能無法正常顯示，因此不推薦，不過這裏還是附上CDN鏈接：CDN鏈接
layer彈出層
這個是該框架的代表作，常用於一些公告、提示框、輪播相冊等場景，舉例：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>彈層使用</title>
<link rel="stylesheet" href="./layui/css/layui.css" media="all">
</head>
<body>
<div class="layui-btn layui-btn-primary layer-demolist" id="test1">我下面會出現一個彈層</div>
</body>
<script src="./layui/layui.js"></script>
<script>
layui.use('layer', function () {
var layer = layui.layer;
layer.tips('上', '#test1', { // 表示在id=test1的地方顯示彈層
tips: 3, // 1/2/3/4分別表示從：上/右/下/左顯示彈層
time: 0, // 設置爲0表示不消失
});
});
</script>
</html>
結果圖：
多個彈層示例
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>彈層使用</title>
<link rel="stylesheet" href="./layui/css/layui.css" media="all">
</head>
<body>
<button id="show" class="layui-btn layui-btn-primary">顯示彈層</button>
<button class="layui-btn del">刪除彈層1</button>
<button class="layui-btn layui-btn-normal del">刪除彈層2</button>
<button class="layui-btn layui-btn-warm del">刪除彈層3</button>
<button class="layui-btn layui-btn-danger del">刪除彈層4</button>
<br><br><br>
<center>
<div class="layui-btn layui-btn-primary layer-demolist" id="test1">我上面會出現一個彈層</div>
<div class="layui-btn layui-btn-primary layer-demolist" id="test2">我右面會出現一個彈層</div>
<br>
<div class="layui-btn layui-btn-primary layer-demolist" id="test3">我下面會出現一個彈層</div>
<div class="layui-btn layui-btn-primary layer-demolist" id="test4">我左面會出現一個彈層</div>
</center>
</body>
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.js"></script>
<script src="./layui/layui.js"></script>
<script>
layui.use('layer', function () {
$('#show').click(function () {
for (i = 1; i <= 4; i++) {
layui.layer.tips(i, '#test' + i, { // 表示在id=test1的地方顯示彈層
tips: i, // 1/2/3/4分別表示從：上/右/下/左顯示彈層
// area: ['200px', '20px'], // 設置長高
time: 0, // 設置爲0表示不消失
tipsMore: true, //支持多個彈層
success: function (layero, index) {
// console.log(layero, index);
layero.addClass(i + "-error"); // 添加一個class
layero.children().eq(0).removeAttr("style");
layero.children().eq(0).css("line-height", "20px"); // 設置行高
// 給當前的標籤設置id及樣式
}
});
}
});
$('.del').click(function () {
current = $(this).index();
$("." + current + '-error').remove();
// 刪除按鈕對應彈層，這裏沒有使用官方提供的close方法
// 因爲close方法是根據彈層的索引來進行刪除
// 但是每點擊依次顯示彈層，就會多4個彈層，那麼其將無法把你希望的彈層都刪除
})
});
