This article shares with you the detailed method of implementing dynamic and static paging in layui through examples, as well as the effect display. Friends in need can follow and learn from it.

The development and management backend is a link that every developer must be familiar with. As backend programmers, all the company's confidential data is in our hands, so at this time, if you are not a core member of the company, We cannot have access to certain data. At this time, all the work fell into our hands. From PS to Linux, we needed to do it ourselves. Fortunately, we discovered layui, a front-end framework, which greatly reduced our workload. pressure.

Today we will first learn how layui implements dynamic data tables, static data tables, and table paging, which also involves dynamic refresh of data tables, use of data table toolbars, form submission and other functions. This static paging is also applicable to information websites. My working development environment is the Debian desktop version, so all experiments are also tested on Debian.

Implementation process

I have written the business logic in the comments, so that everyone can be more friendly. Avoid reading the code for a while and getting distracted while reading the instructions

Front-end code:

Backend php Code

Form module: http://www.layui.com/doc/ modules/table.html

When debugging, you can open the console and network of chrome, firefox to view, carefully study and analyze

Data table toolbar events

Toolbar means that you can operate the corresponding row in the row cell, because using layui's element monitoring, it is easy to get the data corresponding to the entire row.

For example, getting the data of the form , you only need to listen to the form submission event, and you can directly obtain all parameters and values ​​​​at once: 

<script>
  layui.use([&#39;form&#39;,&#39;jquery&#39;],function(){
    let form = layui.form,
      $ = layui.$;
    form.on(&#39;submit(fuck-submit)&#39;, function(data){
      if(data.field.password && data.field.password.length < 5){
        layer.msg(&#39;密码不能小于５位&#39;);
        return false;
      }
      $.post(&#39;index.php?&a=adminEdit&op=update&uid=&#39;+data.field.uid,{
          username:data.field.username,
          password:data.field.password,
          level:data.field.level,
          is_enabled:data.field.is_enabled
        }, function(responseText){
          //console.log(responseText);
          if(responseText.errno === 8){
            layer.msg(responseText.errstr,{icon:6});
            return false;
          } else {
            layer.msg(responseText.errstr,{icon:5});
            location.reload();
          }
        },&#39;json&#39;
      );
      return false;
    });
  });
</script>

Here is the official document: 

form.on(&#39;submit(*)&#39;, function(data){
 console.log(data.elem) //被执行事件的元素DOM对象，一般为button对象
 console.log(data.form) //被执行提交的form对象，一般在存在form标签时才会返回
 console.log(data.field) //当前容器的全部表单字段，名值对形式：{name: value}
 return false; //阻止表单跳转。如果需要表单跳转，去掉这段即可。
});

The data table we want to operate today also uses this method. First, let’s take a look at how to generate and render the toolbar:

You only need to insert a container in the body part. Note that the type of javascript here is text/html. This is for layui parsing. The d here is the data when we render the table. All The values ​​of the fields can be obtained in this d

<table class="layui-hide" lay-filter="fucktest" id="test"></table>
  <script type="text/html" id="barDemo">
    <a class="layui-btn layui-btn-xs" user_id="{{d.admin_id}}" lay-event="edit">编辑</a>
  </script>
