Vue三级联动
2021/8/26 23:09:26
本文主要是介绍Vue三级联动,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
数据层:
public List<City> GetCity(int Pid) { return db.City.Where(w => w.ParentId == Pid).ToList(); }
控制器:
public ActionResult GetCity(int Pid) { return Json(dal.GetCity(Pid), JsonRequestBehavior.AllowGet); }
Vue语法:
let app = new Vue({ el: "#app", data() { return { FormData: { ProvinceId: "0", CityId: "0", CountyId: "0", }, selectItem: [], provinceItem: [], cityItem: [], countyItem: [] }; }, methods: { getProvince() { axios.get('/Employee/GetCity?pid=0').then(res => { this.provinceItem = res.data; this.provinceItem.unshift({ "CId": "0", "CName": "请选择" }) }) }, getCity() { this.cityItem = []; this.countyItem = []; axios.get('/Employee/GetCity?pid=' + this.FormData.ProvinceId).then(res => { this.cityItem = res.data; this.cityItem.unshift({ "CId": "0", "CName": "请选择" }); this.formData.CityId = this.cityItem[0].CId; }) }, getCounty() { this.countyItem = []; axios.get('/Employee/GetCity?pid=' + this.FormData.CityId).then(res => { this.countyItem = res.data; this.countyItem.unshift({ "CId": "0", "CName": "请选择" }); this.formData.CountyId = this.countyItem[0].CId; }) }, }, created: function () { this.getDept(); this.getProvince(); } })
