Question

场景：当我点击ext：ComboBox中的项目并想要将项目选择值设置为cookie变量时。最后，在我点击ext：Button后，ext：Label获取cookie值并显示它。

但是我收到一个错误：Ext.Ajax通信失败，任何帮助都将不胜感激。

ASPX：

 <ext:ComboBox ID="ComboBox1" runat="server" StoreID="Store1" Width="100" Editable="false"
                                DisplayField="name" ValueField="value" Mode="Local" TriggerAction="All`enter code here`" EmptyText="Select a locale...">

.....

aspx.cs

protected  void lngIndexChanged(object sender, DirectEventArgs e)
    {
        //Sets the cookie that is to be used by Global.asax
        HttpCookie cookie = new HttpCookie("CultureInfo");
        cookie.Value = ComboBox1.SelectedItem.Value ;
        Response.Cookies.Add(cookie);

        Label1.Text = cookie.Value;
        //Set the culture and reload for immediate effect. 
        //Future effects are handled by Global.asax
        Thread.CurrentThread.CurrentCulture = new CultureInfo(ComboBox1.SelectedItem.Value);
        Thread.CurrentThread.CurrentUICulture = new CultureInfo(ComboBox1.SelectedItem.Value);


    }

我测试了您的代码，它似乎正常工作。没有抛出异常，Cookie .Value被正确保留。

以下是演示完整方案的示例，其中包括第二个用于在将来的请求中获取Cookie .Value的按钮。

示例

<%@ Page Language="C#" %> <%@ Import Namespace="System.Threading" %> <%@ Import Namespace="System.Globalization" %> <%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %> <script runat="server"> protected void ComboBox1_Select(object sender, DirectEventArgs e) { // Sets the cookie that is to be used by Global.asax HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = this.ComboBox1.SelectedItem.Value; this.Response.Cookies.Add(cookie); this.Label1.Text = "Cookie Value: " + cookie.Value; // Set the culture and reload for immediate effect. // Future effects are handled by Global.asax Thread.CurrentThread.CurrentCulture = new CultureInfo(this.ComboBox1.SelectedItem.Value); Thread.CurrentThread.CurrentUICulture = new CultureInfo(this.ComboBox1.SelectedItem.Value); } protected void Button1_Click(object sender, DirectEventArgs e) { this.Label1.Text = "Cookie Value Again : " + this.Request.Cookies["CultureInfo"].Value; } </script> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Ext.NET Example</title> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:ComboBox ID="ComboBox1" runat="server" OnDirectSelect="ComboBox1_Select" EmptyText="Select a locale..."> <Items> <ext:ListItem Text="Australia" Value="en-AU" /> <ext:ListItem Text="Brasil" Value="br-BR" /> <ext:ListItem Text="Canada" Value="en-CA" /> <ext:ListItem Text="Denmark" Value="da-DK" /> </Items> </ext:ComboBox> <br /> <ext:Button runat="server" Text="Get Cookie Value" OnDirectClick="Button1_Click" /> <br /> <ext:Label ID="Label1" runat="server" /> </form> </body> </html>

如何在ext.net中设置（获取）cookie值
