1.1:下拉框条件:后台取得ViewBag传给前台
MonitorController: public ActionResult BigData(): //下拉框筛选条件 var result = MonitorBLL.GetSoilPlantCountByCode(loginSoil); var r = (object)result.data; ViewBag.soilplantcount = r; // loginSoil是登录用户 public static ResponseModel GetSoilPlantCountByCode(Farm_SoilModel loginSoil) { if (loginSoil.IsEmpty()) { return ResponseHelper.SetData(ResponseEnum.ParaError); } // Log4.Write("传入参数:组织编号=" + soilcode); string sql = ""; sql = "select * from Farm_SoilItem where SoilCode='" + loginSoil.SoilCode + "'"; Dictionary<string, string> Plant = new Dictionary<string, string>(); var json = DapperDAL.QueryList(sql);//产量json近两个月的; for (var i = 0; i < json.Count; i++) { Plant.Add(json[i]["SoilItemCode"],json[i]["SoilItemName"]); } return ResponseHelper.SetData(ResponseEnum.Success, "获取成功", Plant); } BigData.cshtml: <select id="selectID"> @foreach (var item in ViewBag.soilplantcount) { <option id=" @item.Key" value=" @item.Key"> @item.Value</option> } </select>
1.2点击下拉框事件:
//绑定下拉框change事件,当下来框改变时调用 SelectChange()方法 $("#selectID").change(function () { SelectChange(); }); function SelectChange() { //获取下拉框选中项的text属性值 var selectText = $("#selectID").find("option:selected").text(); alert(selectText); $.ajax({ url: "/MonitorApi/GetSoilSeedCountYByCode", type: "post", dataType: "json", data: { soilitemcode: selectText }, success: function (res) { // //var cityName = $(this).text();不能这样写 }, error: function () { alert("网络错误"); } }); }
1.3套到饼图中ajax加载
$("#selectID").change(function () { SelectChange1(); }); var name; var val; function SelectChange1() { var selectText = $("#selectID").find("option:selected").val(); //alert(selectText); //获取下拉框选中项的text属性值 //劳动及产品统计(年) var worldMapContainer = document.getElementById('box3');
