layui框架treetable扩展使用方法

在使用layui的表格的时候有时候我们需要使用类似于有层级关系的数据，比如权限管理等等。需要形成如下图类似的表格，我们可以使用treetable这个插件来实现，如下图所示：

1、加载对用的文件

<link rel="stylesheet" href="../lib/layui-v2.5.5/css/layui.css" media="all">
    <!--layui的js文件需要加载-->
    <script src="../lib/layui-v2.5.5/layui.js" charset="utf-8"></script>
    <!--layui的配置文件需要加载-->
    <script src="../js/lay-config.js?v=1.0.4" charset="utf-8"></script>

2、全部展开和全部全部折叠

<div>
            <!--全部折叠|全部展开-->
            <div class="layui-btn-group">
                <button class="layui-btn" id="btn-expand">全部展开</button>
                <button class="layui-btn layui-btn-normal" id="btn-fold">全部折叠</button>
            </div>
            <table id="munu-table" class="layui-table" lay-filter="munu-table"></table>
        </div>

3、展示对应列表

<table id="munu-table" class="layui-table" lay-filter="munu-table"></table>

4、下面是layui核心代码（重点）

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>menu</title>
    <!--layui的css文件展示样式-->
    <link rel="stylesheet" href="../lib/layui-v2.5.5/css/layui.css" media="all">
    <!--layui的js文件需要加载-->
    <script src="../lib/layui-v2.5.5/layui.js" charset="utf-8"></script>
    <!--layui的配置文件需要加载-->
<script src="../js/lay-config.js?v=1.0.4" charset="utf-8"></script>
</head>
<body>
<div class="layuimini-container">
    <div class="layuimini-main">
        <blockquote class="layui-elem-quote">
            <a href="#" target="_blank" class="layui-btn layui-btn-danger">实例demo</a>
        </blockquote>
        <div>
            <!--全部折叠|全部展开-->
            <div class="layui-btn-group">
                <button class="layui-btn" id="btn-expand">全部展开</button>
                <button class="layui-btn layui-btn-normal" id="btn-fold">全部折叠</button>
            </div>
            <table id="munu-table" class="layui-table" lay-filter="munu-table"></table>
        </div>
    </div>
</div>
<!-- 操作列 -->
<script type="text/html" id="auth-state">
    <a class="layui-btn layui-btn-primary layui-btn-xs" lay-event="edit">修改</a>
    <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
</script>

<script>
    layui.use(['treetable'], function () {
        var $ = layui.jquery;
        var treetable = layui.treetable;

        // 渲染表格
        layer.load(2);
        treetable.render({
            treeColIndex: 1,//层级关系展示在第几列
            treeSpid: -1,//是否有最高父id没有-1表示
            treeIdName: 'authorityId',//每条数据id 字段
            treePidName: 'parentId', //每天数据父id字段
            elem: '#munu-table',//表单id
            url: '../api/menus.json',//请求url接口
            page: false,
            cols: [[
                {type: 'numbers'},
                {field: 'authorityName', minWidth: 200, title: '权限名称'},
                {field: 'authority', title: '权限标识'},
                {field: 'menuUrl', title: '菜单url'},
                {field: 'orderNumber', width: 80, align: 'center', title: '排序号'},
                {
                    field: 'isMenu', width: 80, align: 'center', templet: function (d) {
                        if (d.isMenu == 1) {
                            return '<span class="layui-badge layui-bg-gray">按钮</span>';
                        }
                        if (d.parentId == -1) {
                            return '<span class="layui-badge layui-bg-blue">目录</span>';
                        } else {
                            return '<span class="layui-badge-rim">菜单</span>';
                        }
                    }, title: '类型'
                },
                {templet: '#auth-state', width: 120, align: 'center', title: '操作'}
            ]],
            done: function () {
                layer.closeAll('loading');
            }
        });

        //全部展开
        $('#btn-expand').click(function () {
            treetable.expandAll('#munu-table');
        });
        //全部折叠
        $('#btn-fold').click(function () {
            treetable.foldAll('#munu-table');
        });
    });
</script>
</body>
</html>

5.展示json数据(menus.json)
