下载后，treeTable.js、treeTable.css 的放置目录分别为： layuiadmin/modules/treeTable.js layuiadmin/modules/treeTable/treeTable.css

页面元素：

定义：

layui.config({

base: '${ctxLayui}/layuiadmin/'

}).extend({

index: 'lib/index'

}).use(['index', 'table','dict','laydate','util','treeTable'], function(){

var $ = layui.$,table = layui.table,form = layui.form;

var dict = layui.dict;

var laydate = layui.laydate;

var admin = layui.admin;

var util = layui.util;

var treeTable = layui.treeTable;

渲染：

var insTb = treeTable.render({

elem: '#businessConfigListTable',

tree: {

iconIndex: 1, // 折叠图标显示在第几列

idName: 'id', // 自定义id字段的名称

pidName: 'parentId', // 自定义标识是否还有子节点的字段名称

},

cols: [

{type: 'checkbox', fixed: 'left'},

{type: 'numbers',width: 120,style:'text-align:left'},

// {field: 'id', title: 'ID',width: 180},

{field: 'type', title: '类型', width: 120,templet:tplType},

{field: 'name', title: '名称', width: 200},

{field: 'value', title: '值'},

{field: 'sortOrder', title: '排序', width: 120},

{field: 'status', title: '状态', width: 150,templet:tplStatus},

{title:'操作', toolbar: '#businessConfigListTable-bar', width:120}

],

reqData: function(data, callback) {

// 在这里写ajax请求，通过callback方法回调数据

var url = ctx+'/business/businessConfig/businessConfigTreeList';

var rtn = admin.syncReq(url,{});

var rtnData = rtn.data;

for(var i=0;i

var vo = rtnData[i];

vo.open = true;

}

callback(rtnData);

}

,height: 'full-99'

});

接口：business/businessConfig/businessConfigTreeList， 如下：

@RequestMapping(value = "businessConfigTreeList")

@ResponseBody

public BaseResp businessConfigTreeList(@ModelAttribute("command") BusinessConfigQo command){

BaseResp resp = new BaseResp();

try{

List list = businessConfigService.businessConfigTreeList(command);

resp.setData(list);

}catch (Exception e){

error(logger,resp,e);

}

return resp;

}

其中 BaseResp 结构：

/**

* 应答返回码

*/

private int code = RC_OK;

/**

* 应答返回消息

*/

private String msg;

/**

* 跳转url

*/

private String url = "";

private int count;

private boolean success = false;// 是否成功

private Object data;

service层获取数据，递归：

public List businessConfigTreeList(BusinessConfigQo command) throws Exception{

command.setParentId(0l);

command.setLimit(99999);

List list = this.businessConfigMapper.query(command);

for(BusinessConfigPo rec:list){

List children = getChildrenConfig(rec);

rec.setChildren(children);

}

return list;

}

private List getChildrenConfig(BusinessConfigPo rec) throws Exception{

BusinessConfigQo qo = new BusinessConfigQo();

qo.setLimit(99999);

qo.setParentId(rec.getId());

List list = this.businessConfigMapper.query(qo);

if(list==null){

return null;

}

for(BusinessConfigPo child:list){

List children = getChildrenConfig(child);

child.setChildren(children);

}

return list;

}
