怎么将json字符串转换成树结构2

我有这样格式的json结构，想按照json内的type的值，自动归类生成一个树结构。如下图所示：



      var initData = [

{"dataId":"21","parentid":"2","name":"A厂","type":"水厂"},

{"dataId":"31","parentid":"3","name":"B厂","type":"水厂"},

{"dataId":"32","parentid":"3","name":"C厂","type":"水厂"},

{"dataId":"51","parentid":"5","name":"A抽水站","type":"抽水站"},

{"dataId":"91","parentid":"9","name":"D厂","type":"污水厂"},

{"dataId":"111","parentid":"11","name":"E厂","type":"水厂"},

{"dataId":"112","parentid":"11","name":"F厂","type":"水厂"},

{"dataId":"113","parentid":"11","name":"G厂","type":"水厂"},

{"dataId":"114","parentid":"11","name":"H厂","type":"水厂"},

{"dataId":"115","parentid":"11","name":"I厂","type":"水厂"},

{"dataId":"121","parentid":"12","name":"J厂","type":"水厂"},

{"dataId":"122","parentid":"12","name":"K厂","type":"水厂"},

{"dataId":"123","parentid":"12","name":"L厂","type":"水厂"},

{"dataId":"124","parentid":"12","name":"M厂","type":"水厂"},

{"dataId":"131","parentid":"13","name":"N厂","type":"水厂"},

{"dataId":"D1117","parentid":"111","name":"A调度","type":"调度监测"},

{"dataId":"D1126","parentid":"112","name":"B调度","type":"调度监测"},

{"dataId":"D1211","parentid":"121","name":"A加压站","type":"加压站"},

{"dataId":"D1212","parentid":"121","name":"B加压站","type":"加压站"},

{"dataId":"D1213","parentid":"121","name":"C调度","type":"调度监测"},

{"dataId":"D1224","parentid":"122","name":"D调度","type":"调度监测"},

{"dataId":"D1234","parentid":"123","name":"C加压站","type":"加压站"},

{"dataId":"D1235","parentid":"123","name":"E调度","type":"调度监测"},

{"dataId":"D8101","parentid":"81","name":"A二次加压","type":"二次加压"}
