之前的一篇文章中介绍的是easyui页面获取c#后台代码的数据，也可以用另一种方式来获取：
html：
<table id="pressure"></table>js:
function loadMessage() {$('#pressure').datagrid({height: 500,url: '/Home/RealtimeData',method: 'POST',idField: 'ElementId',striped: true,fitColumns: true,singleSelect: false,rownumbers: true,pagination: false,nowrap: false,pageSize: 10,pageList: [10, 20, 50, 100, 150, 200],showFooter: true,columns: [[{ field: 'ck', checkbox: true },{ field: 'ElementId', title: '序号', align: 'left' },{ field: 'Label', title: '标识', align: 'left' },{ field: 'Meter_Name', title: '名称', align: 'left' },{ field: 'Station_Un', title: '营销公司', align: 'left' },{ field: 'MeasureAre', title: '计量区', align: 'left' },{ field: 'DistrictAr', title: '行政区', align: 'left' },{ field: 'Explain', title: '监测点类型', align: 'left' }]],onBeforeLoad: function (param) {},onLoadSuccess: function (data) {if (data) {$.each(data.rows, function (index, item) {if (item.Display == 1) {$('#pressure').datagrid('checkRow', index);}});}},onLoadError: function () {},onClickCell: function (rowIndex, field, value) {}});
}c#:
public ActionResult RealtimeData(){var workers = from w in db.METERselect w;workers = workers.Where(w => w.Meter_Type == 2 || w.Meter_Type == 4);workers = workers.OrderBy(w => w.ElementId);var result = from worker in workersselect new{worker.ElementId,worker.Label,worker.Meter_Name,worker.Station_Un,worker.MeasureAre,worker.DistrictAr,worker.Explain,worker.Display};var jsonResult = new { total = workers.Count(), rows = result };string str = JsonSerializeHelper.SerializeToJson(jsonResult, "yyyy'-'MM'-'dd' 'HH':'mm':'ss");return Content(str);}
