treeTable 模块下载: https://gitee.com/whvse/treetable-lay/tree/master/2.x
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:
<div > <table class="layui-hide" id="businessConfigListTable" lay-filter="businessConfigListTable"></table> </div>
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<rtnData.length;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<BusinessConfigPo> 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<BusinessConfigPo> businessConfigTreeList(BusinessConfigQo command) throws Exception{ command.setParentId(0l); command.setLimit(99999); List<BusinessConfigPo> list = this.businessConfigMapper.query(command); for(BusinessConfigPo rec:list){ List<BusinessConfigPo> children = getChildrenConfig(rec); rec.setChildren(children); } return list; } private List<BusinessConfigPo> getChildrenConfig(BusinessConfigPo rec) throws Exception{ BusinessConfigQo qo = new BusinessConfigQo(); qo.setLimit(99999); qo.setParentId(rec.getId()); List<BusinessConfigPo> list = this.businessConfigMapper.query(qo); if(list==null){ return null; } for(BusinessConfigPo child:list){ List<BusinessConfigPo> children = getChildrenConfig(child); child.setChildren(children); } return list; }
