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：

 <link rel="stylesheet" href="/自己的地址/./layui/css/layui.css" rel="external nofollow" media="all">
 <script type="text/javascript" src="/UploadFiles/2021-04-02/layui.js">

2、输出： hello world


<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-3.0.0.min.js">

3、基于layui三级联动



html
<!DOCTYPE html>
<html>
<head>
 <meta charset="utf-8">
 <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
 <title>基于 Layui form 组件的省市区联动选择的实现</title>
 
 <script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-3.0.0.min.js">



province.js
var defaults = {
 s1: 'provid',
 s2: 'cityid',
 s3: 'areaid',
 v1: null,
 v2: null,
 v3: null
};
var $form;
var form;
var $;
layui.define(['jquery', 'form'], function () {
 $ = layui.jquery;
 form = layui.form;
 $form = $('form');
 treeSelect(defaults);
});
function treeSelect(config) {
 config.v1 = config.v1 "");
  config.v1 = data.value "");
  config.v2 = data.value "<option>").text(k).val(v);
  if (v == d) { $opt.attr("selected", "selected") }
  $opt.appendTo($o);
 }
}
