BootstrapTable.prototype.initServer = function (silent, query) { var that = this, data = {}, params = { pageSize: this.options.pageSize === this.options.formatAllRows() ? this.options.totalRows : this.options.pageSize, pageNumber: this.options.pageNumber, searchText: this.searchText, sortName: this.options.sortName, sortOrder: this.options.sortOrder }; if (!this.options.url) { return; } if (this.options.queryParamsType === 'limit') { params = { search: params.searchText, sort: params.sortName, order: params.sortOrder }; if (this.options.pagination) { params.limit = this.options.pageSize === this.options.formatAllRows() ? this.options.totalRows : this.options.pageSize; params.offset = this.options.pageSize === this.options.formatAllRows() ? : this.options.pageSize * (this.options.pageNumber - 1); } }
服务器后台实现三个功能，一个是根据数据加载，以及数据修改和删除。
public ActionResult GetJsonHistoryDatas() { var displayStart = int.Parse(Request["offset"]); var displayLength = int.Parse(Request["pageSize"]); var meterID = int.Parse(Request["MeterID"]); var order = Request["sortOrder"]; var historyDatas = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID). OrderByDescending(p => p.Timestamp). Skip(displayStart). Take(displayLength).ToList();//显示最近的 displayLength 条数据 if ("asc" == order) { historyDatas = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID). OrderBy(p => p.Timestamp). Skip(displayStart). Take(displayLength).ToList();//显示最早的 displayLength 条数据 } int historyDataTotal = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID).Count();//数据总条数 //时间过滤 if (!String.IsNullOrEmpty(Request["begintime"])) { DateTime begintime = DateTime.Parse(Request["begintime"]); DateTime endtime = DateTime.Parse(Request["endtime"]); historyDatas = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID). Where(p => p.Timestamp > begintime && p.Timestamp < endtime). OrderByDescending(p => p.Timestamp). Skip(displayStart). Take(displayLength).ToList();//显示最近的 displayLength 条数据 if ("asc" == order) { historyDatas = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID). Where(p => p.Timestamp > begintime && p.Timestamp < endtime). OrderBy(p => p.Timestamp). Skip(displayStart). Take(displayLength).ToList();//显示最早的 displayLength 条数据 } historyDataTotal = db.MeterMeasureHistories. Where(p => p.MeterMeasure.MeterID == meterID). Where(p => p.Timestamp > begintime && p.Timestamp < endtime).Count();//数据总条数 } List<MeterMeasureHistoryDataViewModels> ListMeterMeasureHistories = new List<MeterMeasureHistoryDataViewModels>(); foreach (var item in historyDatas) { ListMeterMeasureHistories.Add(new MeterMeasureHistoryDataViewModels { MeterMeasureHistoryID = item.MeterMeasureHistoryID, Value = item.Value, Timestamp = item.Timestamp.ToString() }); } string jsonDataTable = JsonConvert.SerializeObject( new { total = historyDataTotal, rows = ListMeterMeasureHistories }); return Content(jsonDataTable); }
其中实现了分页以及数据查询，返回json数据，返回的json数据包括total、rows两个对象，total表示数据总数，rows表示需要显示的数据。MeterMeasureHistoryDateView如下，对应Table中的field值：
public class MeterMeasureHistoryDataViewModels { public int MeterMeasureHistoryID { get; set; } public double Value { get; set; } public string Timestamp { get; set; } }
数据修改函数：
[HttpPost] public JsonResult EditMeterMeasureHistoryData() { var metermeasurehistoryid = int.Parse(Request["MeterMeasureHistoryID"]); var metermeasurehistoryvalue = double.Parse(Request["Value"]); var metermeasurehistorytime = DateTime.Parse(Request["Timestamp"]); var metermeasurehistoryInDb = db.MeterMeasureHistories.Find(metermeasurehistoryid); metermeasurehistoryInDb.Value = metermeasurehistoryvalue; metermeasurehistoryInDb.Timestamp = metermeasurehistorytime; db.SaveChanges(); var changedData = new MeterMeasureHistoryDataViewModels { MeterMeasureHistoryID = metermeasurehistoryInDb.MeterMeasureHistoryID, Value = metermeasurehistoryInDb.Value, Timestamp = metermeasurehistoryInDb.Timestamp.ToString() }; JsonResult js = new JsonResult(); js.Data = Json(changedData); return js; }
数据删除函数：
