treeTable 实现分页显示数据

https://whvse.gitee.io/treetable-lay/demo/

默认的treetable 是没有分页查询数据的，自己改装了一下

  <title>Layui树形表格</title>
<div class="page-wrapper">
    <table id="demoTreeTb"></table>

    <div id="laypages"></div>
</div>

<!-- 表格操作列 -->
<script type="text/html" id="tbBar">
    <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>
    pagefun(1, 15); // 使用 分页来显示我的团队
    function pagefun(page, size) {
        layui.use(['admin', 'form', 'treeTable', 'laypage'], function () {
            var $ = layui.$, admin = layui.admin, treeTable = layui.treeTable, laypage = layui.laypage;
            //计算出 分页数
            $.get("http://192.168.20.114/api/Home/GetmenuCount", { curr: page, limit: size }, function (result) {
                laypage.render({
                    elem: 'laypages',
                    count: result.count,//总页数
                    curr: result.curr,//当前页
                    limit: 15,
                    limits: [15, 20, 30, 40, 50, 60],
