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_ID,Consumption_Factory_Style_No,Customer_Style_No,Quantity,Writer,Sample_Type,Write_Date,Confirmation,Approval 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_ID,Consumption_Factory_Style_No,Customer_Style_No,Quantity,Writer,Sample_Type,Write_Date,Confirmation,Approval 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, SizeNum, "Consumption");
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？
