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：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" m
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>
