How to introduce treetable in layui

To introduce TreeTable into LAYUI, you need to import the LAYUI library and TreeTable module first, then create the table structure in HTML and specify the lay-filter attribute, and finally obtain the table object through the layui.treeTable API to expand/ Operations such as folding, getting selected nodes, updating data, etc.

How to introduce TreeTable in LAYUI

The TreeTable component of LAYUI is a table with a tree structure. Implement hierarchical display and expand/collapse operations of data. To introduce TreeTable, you need to follow the following steps:

1. Import the LAYUI library

In your HTML page, you first need to import the LAYUI library:

<code class="html"><script src="/path/to/layui.js"></script></code>

2. Import the TreeTable module

Then, you need to import the TreeTable module:

<code class="html"><script>
  layui.use('treeTable');
</script></code>

3. Create a table structure in HTML

Create a table structure containing the treetable class name and assign it the lay-filter attribute:

<code class="html"><table class="layui-table" lay-filter="myTreeTable">
  <thead>
    <tr>
      <th>表头 1</th>
      <th>表头 2</th>
      <th>表头 3</th>
    </tr>
  </thead>
  <tbody>
    <!-- 表体数据 -->
  </tbody>
</table></code>

4. Get the table object

In JavaScript code, use layui.treeTable API to obtain the table object:

<code class="javascript">var myTreeTable = layui.treeTable.render({
  elem: '#myTreeTable'
});</code>

5. Operate TreeTable

Through the table object, you can operate the TreeTable, for example:

• Expand/collapse nodes: myTreeTable.expand(nodeId) / myTreeTable.collapse(nodeId)
• Get selected nodes: myTreeTable.getSelectedNodes()
• Update data: myTreeTable.reload({data: [{}]})
