How to automatically refresh layui tables

Step one: Set up the environment.

1. The environment setup of layui is very simple, similar to query. It can be used directly as long as it is imported.

1.1: Introduce js and styles

2. If you make a complete interactive request the day before and after, you need to build a responsive background environment. (This article does not introduce the construction of the background environment)

Step 2: Download layui.

Website: https://www.layui.com/

1. The first step is to open the layui download URL

2. Download the layui dependency package

3. Check the dependency packages.

Step 3: Code implementation.

1. Implementation of html code part

<fieldset class="layui-elem-field layui-field-title" style="margin-top: 50px;">
  <legend>人员数据</legend>
</fieldset>
<table class="layui-hide" id="demo" lay-filter="pManageTable"></table>
 
<script type="text/html" id="barDemo">
  <a class="layui-btn layui-btn-primary layui-btn-xs" lay-event="detail">查看</a>
  <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
  <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
</script>

2. Implementation of js code.

<script src="layui/layui.all.js" charset="utf-8"></script>
<script>
layui.config({
  version: &#39;1545041465443&#39; //为了更新 js 缓存，可忽略
});
 
layui.use([&#39;laydate&#39;, &#39;laypage&#39;, &#39;table&#39;, &#39;element&#39;], function(){
  var laydate = layui.laydate //日期
  ,laypage = layui.laypage //分页
  ,table = layui.table //表格
  ,element = layui.element //元素操作
  
  //默认第一次初始化调用执行一个 table 实例
  var tableIns = table.render({
    elem: &#39;#demo&#39;
    ,height: 450
    ,url:&#39;demo.json&#39; //数据接口
    ,title: &#39;用户表&#39;
    ,page: true //开启分页
    ,toolbar: &#39;default&#39; //开启工具栏，此处显示默认图标，可以自定义模板，详见文档
    ,totalRow: true //开启合计行
    ,cols: [[ //表头
      {type: &#39;checkbox&#39;, fixed: &#39;left&#39;}
      ,{field: &#39;id&#39;, title: &#39;ID&#39;, width:80, sort: true, fixed: &#39;left&#39;}
      ,{field: &#39;username&#39;, title: &#39;菜品名称&#39;, width:105}
      ,{field: &#39;sex&#39;, title: &#39;菜单类别&#39;, width: 105, sort: true}
      ,{field: &#39;city&#39;, title: &#39;所属菜系&#39;, width:115, sort: true}
      ,{field: &#39;sign&#39;, title: &#39;签名&#39;, width: 80, sort: true, totalRow: true}
      ,{field: &#39;experience&#39;, title: &#39;积分&#39;, width: 85, sort: true, totalRow: true}
      ,{field: &#39;score&#39;, title: &#39;评分&#39;, width: 100}
      ,{field: &#39;classify&#39;, title: &#39;职业&#39;, width: 100}
      ,{field: &#39;wealth&#39;, title: &#39;财富&#39;, width: 100}
      ,{fixed: &#39;right&#39;, width: 165, align:&#39;center&#39;, toolbar: &#39;#barDemo&#39;}
    ]]
  });

The button or js is called regularly, and the query button is called

  function callBack(){
  //第二次调用
 tableIns.reload({
    where: {'username':"user-0"}/设定异步数据接口的额外参数，任意设
    ,page: {
      curr: 1 //重新从第 1 页开始
    }
 });
  }
  
  
});

Step 4: Test.

1. Open the page data table and display successfully.

2. Click the page number of the page turning button to refresh the table

3. Call layui's request to refresh the page.
