Question

        var zTreeObj;
        var setting = {
            view:{
                showIcon:false
            },
            async: {
                enable: true,
                url: apiPath + 'system/lay/dept/noOpenList',
                autoParam: ["deptId"],
                otherParam: {"deptId":""},
                dataFilter: function(treeId, parentNode, res){
                    if(res.code == 0){
                        return res.rows
                    }
                }
            },
            data: {
                key: {
                    name: "deptName"
                }
            },
            callback: {
                onClick: function(event, treeId, treeNode){
                    deptId = treeNode.deptId
                    var queryData = {param:{
                        deptId: deptId
                    }};

                     table.reload(SysUserProperty.tableId, {
                            where: queryData, page: {curr:1}
                     });
                }
            }
        };

        $(document).ready(function () {
            zTreeObj = $.fn.zTree.init($("#newTree"), setting);
        });
