如何使用ajax调用将Datatable导出到Excel文件

我已经试过这个导出数据表到Excel文件我能够下载excel文件，当我通过SOAP API调用，但是当我从ajax调用它时，我没有得到任何错误，我无法下载Excel文件。

Ajax / JavaScript代码：

function getWorkOrders(wono) { $.ajax({ dataType: "json", type: "POST", url: 'AdminWeb.asmx/GetWorkOrdersDetails', data: 'id=0&wono=' + wono, async: true, success: function (data) { }, error: function (jqXHR, textStatus, errorThrown) { } }); } 

方法：

 DataTable dtResult = DataAccess.GetDataTableFromStoredProcedure("sp_Get_WO", Parameters); //dt = city.GetAllCity();//your datatable string attachment = "attachment; filename=city.xls"; HttpContext.Current.Response.ClearContent() HttpContext.Current.Response.AddHeader("content-disposition", attachment); HttpContext.Current.Response.ContentType = "application/vnd.ms-excel"; string tab = ""; foreach (DataColumn dc in dtResult.Columns) { HttpContext.Current.Response.Write(tab + dc.ColumnName); tab = "\t"; } HttpContext.Current.Response.Write("\n"); int i; foreach (DataRow dr in dtResult.Rows) { tab = ""; for (i = 0; i < dtResult.Columns.Count; i++) { HttpContext.Current.Response.Write(tab + dr[i].ToString()); tab = "\t"; } HttpContext.Current.Response.Write("\n"); } HttpContext.Current.Response.End();
