我在前端的ASP.NET(WebForms)应用程序中使用PageMethods来调用后端的c#函数,该函数从我的数据库中删除一行。删除部分可以工作,但我无法将当前.aspx文件中的url后缀重定向到名为StartPage.aspx的新文件。基本上,我想在按下按钮后将更新从UpdateNetEvent.aspx?ID = [Number]更改为StartPage.aspx。
我的按钮HTML如下:
<asp:Button ID="eventFormResolveBtn" runat="server" Text="Resolve NetEvent" OnClientClick="resolveClicked()" style="background-color:forestgreen;"/>
相应的Javascript函数调用是:
function resolveClicked() {
try {
var currentRowID = document.getElementById('<%=eventFormCurrentRowID.ClientID%>').value;
PageMethods.resolveData(currentRowID, OnSucceeded, OnFailed);
function OnSucceeded(result) {
window.location = result.d;
}
function OnFailed(error) {
alert("An error occured on resolveClicked()");
}
}
catch (err) {
return err;
}
return false;
}
此外,后端的WebMethod调用如下:
[WebMethod]
public static string resolveData(string CurrentRowID)
{
try
{
SqlCommand command;
SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["DatabaseConnectionString"].ConnectionString);
command = new SqlCommand("deleteNetEventRow", sqlConn);
command.Parameters.AddWithValue("@RowID", Convert.ToInt32(CurrentRowID));
command.CommandType = System.Data.CommandType.StoredProcedure;
sqlConn.Open();
command.ExecuteNonQuery();
sqlConn.Close();
return "StartPage.aspx";
}
catch (Exception ex)
{
Console.WriteLine("ERROR: " + ex.ToString()); // Add a log helper to display errors here
return "Error in resolveData WebMethod";
}
}
SQLCommand调用和执行工作正常,但我无法重定向到另一个.aspx页面。
答案 0 :(得分:0)
例如
window.location.href = "http://example.com/new_url";
您可以返回服务器的网址,如下所示:
result.d="http://localhost/StartPage.aspx"
function OnSucceeded(result) {
window.location.href = result.d;
}
