LayUI的使用
1 、引用
1、下载：官网：https://www.layui.com
2、使用方法：直接将解压好的压缩包拖拽到项目内
将以下导入到html中：
|
1
2
|
<link rel="stylesheet" href="/自己的地址/./layui/css/layui.css" rel="external nofollow" media="all"><script type="text/javascript" src="../自己的地址+/layui/layui.js"></script> |
2、输出： hello world

<script type="text/javascript" src="./jquery-3.0.0/jquery-3.0.0.min.js"></script> <!-- 直接将解压的文件辅助到项目 然后导入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：如果是采用非模块化方式（最下面有讲解），此处可换成：./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> |
