LayUI的使用
1 、參考
1、下載：官網：https://www.layui.com
2、使用方法：直接將解壓好的壓縮包拖拽到專案內
將以下匯入到html中：
<link rel="stylesheet" href="/自己的地址/./layui/css/layui.css" media="all">
<script type="text/javascript" src="../自己的地址+/layui/layui.js"></script>
2、輸出： hello world
<script type="text/javascript" src="./jquery-3.0.0/jquery-3.0.0.min.js"></script>
<!-- 直接將解壓的檔案輔助到專案 然后匯入layui.css和layui.js -->
<script type="text/javascript" src="../day/layui/css/layui.css"></script>
<script type="text/javascript" src="../day/layui/layui.js"></script>
<!--提示：如果是采用非模塊化方式（最下面有講解），此處可換成：./layui/layui.all.js -->
<script type="text/javascript" src="./layui/layui.all.js"></script>
</head>
<body>
<script>
// layui.use(['layer', 'form'], function(){
// var layer = layui.layer
// ,form = layui.form;
// layer.msg('Hello World');
// });
$(function(){
layer.msg('Hello World');
})
</script>
</body>
</html>
3、基于layui三級聯動

html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
