一、layui简介：
1、layui是一款采用自身模块规范编写的前端 UI 框架，开源的模块化前 端 UI 框架，区别于那些基于 MVVM 底层的 UI 框架。
2、优点：原生开发模式、模块化、兼容性强
3、layui可作为 PC网页端后台系统与前台界面的速成开发方案
二、目录结构
三、引入方式与表单案例
<!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>layui_learn_one</title> <link rel="stylesheet" href="./layui-2.3.0/css/layui.css"> <script type="text/javascript" src="./layui-2.3.0/layui.js"></script> <script> layui.use(['form', 'layedit', 'laydate'], function(){ var form = layui.form ,layer = layui.layer ,layedit = layui.layedit ,laydate = layui.laydate; //日期 laydate.render({ elem: '#date' }); laydate.render({ elem: '#date1' }); //创建一个编辑器 var editIndex = layedit.build('LAY_demo_editor'); //自定义验证规则 form.verify({ title: function(value){ if(value.length < 5){ return '标题至少得5个字符啊'; } } ,pass: [/(.+){6,12}$/, '密码必须6到12位'] ,content: function(value){ layedit.sync(editIndex); } }); //监听指定开关 form.on('switch(switchTest)', function(data){ layer.msg('开关checked：'+ (this.checked ? 'true' : 'false'), { offset: '6px' }); layer.tips('温馨提示：请注意开关状态的文字可以随意定义，而不仅仅是ON|OFF', data.othis) }); //监听提交 form.on('submit(demo1)', function(data){ layer.alert(JSON.stringify(data.field), { title: '最终的提交信息' }) return false; }); }); </script></head><body> <form action=""> <fieldset class="layui-elem-field layui-field-title" style="margin-top: 20px;"> <legend>表单集合演示</legend> </fieldset> <div>
