问题描述
- JQUERY ajax提交数据到后台,进行数据库查询,然后重新绑定GridView.
- 我在前台放了一个input,type=button点击后触发下面的ajax提交数据到后台。后台处理后对一个GridView进行数据绑定。
前台代码如下:params = JSON.stringify(obj); $.ajax({ type: ""Post"" url: ""/aspx_consumption/Consumption_Home.aspx/AdvanceSearch"" data: params contentType: ""application/json; charset=utf-8"" dataType: ""json"" success: function (data) { alert(date); } error: function (err) { alert(err); } });
后台也没问题:
[WebMethod] public static DataSet AdvanceSearch(string Factory_Style_No string Customer_Style_No string Style_Type string Writer string Start string End string pageSize string pageIndex) { DataSet ds = new DataSet(); string connStr = @System.Configuration.ConfigurationManager.ConnectionStrings[""Sample_Room_ProgressConnectionString""].ToString(); SqlConnection conn = new SqlConnection(connStr); SqlCommand cmd = conn.CreateCommand(); cmd.CommandType = CommandType.Text; //cmd.CommandText = ""SELECT Consumption_IDConsumption_Factory_Style_NoCustomer_Style_NoQuantityWriterSample_TypeWrite_DateConfirmationApproval FROM [Sample_Room_Progress].[dbo].[Consumption] where Factory_Style_No like '%'+@Factory_Style_No+'%' AND Customer_Style_No like '%'+@Customer_Style_No+'%' AND Sample_Type like '%'+@Sample_Type+'%' AND Writer like '%'+@Writer+'%' BETWEEN Write_Date >=@Start AND Write_Date<=@End order by Write_Date DESC""; cmd.CommandText = ""SELECT Consumption_IDConsumption_Factory_Style_NoCustomer_Style_NoQuantityWriterSample_TypeWrite_DateConfirmationApproval FROM [Sample_Room_Progress].[dbo].[Consumption] where Factory_Style_No like '%'+@Factory_Style_No+'%' AND Customer_Style_No like '%'+@Customer_Style_No+'%' AND Sample_Type like '%'+@Sample_Type+'%' AND Writer like '%'+@Writer+'%' AND Write_Date between @Start and @End order by Write_Date DESC""; cmd.Parameters.Add(""@Factory_Style_No"" SqlDbType.NVarChar); cmd.Parameters[""@Factory_Style_No""].Value = Factory_Style_No; cmd.Parameters.Add(""@Customer_Style_No"" SqlDbType.NVarChar); cmd.Parameters[""@Customer_Style_No""].Value = Customer_Style_No; cmd.Parameters.Add(""@Sample_Type"" SqlDbType.NVarChar); cmd.Parameters[""@Sample_Type""].Value = Style_Type; cmd.Parameters.Add(""@Writer"" SqlDbType.NVarChar); cmd.Parameters[""@Writer""].Value =Writer; cmd.Parameters.Add(""@Start"" SqlDbType.DateTime); if (Start == """") { cmd.Parameters[""@Start""].Value = DBNull.Value; } else { cmd.Parameters[""@Start""].Value = Start; } cmd.Parameters.Add(""@End"" SqlDbType.DateTime); if (End == """") { cmd.Parameters[""@End""].Value = DBNull.Value; } else { cmd.Parameters[""@End""].Value = End; } SqlDataAdapter ad = new SqlDataAdapter(); ad.SelectCommand = cmd; int indexNum = Convert.ToInt32(pageIndex); int SizeNum = Convert.ToInt32(pageSize); ad.Fill(ds indexNum SizeNumConsumption""); return ds; }
但是用Jquery ajax提交数据,后台必需要静态方法似乎没法操作ASP.NET控件。有什么办法可以解决?难道我只能用asp.net控件吗?
解决方案
其实前后台是可以互调的,你可以通过调用后台方法去控制,另外现在有很多第三方的js表格组件,用起来比asp.net的表格组件好用多了

解决方案四:
需要使用前台的js更新dg客户端生成的html代码,ajax请求的的aspx和当前页面显示的不是一样的。
可以使用第三方的ui,如easyUI,或者使用微软自带的updatepanel
