layui framework usage guide

What is the layui framework?

layui is a domestic front-end UI framework based on jQuery. It is easy to use, rich in functions, and is loved by many developers.

How to use layui framework?

1. Introduce layui scripts and styles

In the HTML file, introduce layui.js and layui.css ：

<code class="html"><script src="layui/layui.js"></script>
<link rel="stylesheet" href="layui/css/layui.css"></code>

2. Initialize layui

After the DOM element is loaded, execute the layui.use() method to initialize layui:

<code class="javascript">layui.use(['laydate', 'laypage', ...], function(){
  // 使用layui组件
});</code>

3. Use layui components

layui provides a wealth of components, including forms, tables, date range selectors, etc. To use these components, just specify them in the layui.use() method. For example, use the date range selector:

<code class="javascript">layui.use(['laydate'], function(){
  laydate.render({
    elem: '#date',
    type: 'date'
  });
});</code>

4. Configure the theme

layui supports multiple themes. You can specify the theme in HTML after introducing layui.css :

<code class="html"><link rel="stylesheet" href="layui/css/modules/lay/skin/default/layer.css"></code>

5. Plug-in extensions

layui provides a wealth of plug-in extensions that can be introduced as needed. For example, introduce the form validation plug-in:

<code class="javascript">layui.use(['form', 'layer'], function(){
  var form = layui.form;
  form.verify({
    username: function(value){
      if(value.length < 5){
        return '用户名不应小于5个字符';
      }
    }
  });
});</code>
