ASP.NET打開新頁面而不關閉原來的頁面 實例代碼

復制代碼 代碼如下:
Respose.Write("<script     language='javascript'>window.open('"+     url     +"');</script>"); （打開簡潔窗口）：
Respose.Write("<script     language='javascript'>window.open('"     +     url     +     "','','resizable=1,scrollbars=0,status=1,menubar=no,toolbar=no,location=no,     menu=no');</script>");

1. Response.Redirect("XXX.aspx",true)——直接轉向新的頁面，原窗口被代替;
2. Response.Write("<script>window.open('XXX.aspx','_blank')</script>")——原窗口保留，另外新增一個新頁面;
3. Response.Write("<script>window.location='XXX.aspx'</script>")——打開新的頁面，原窗口被代替;
4. Server.Transfer("XXX.aspx")——打開新的頁面;
5. Response.Write("<script>window.showModelessDialog('XXX.aspx')</script>")——原窗口保留，以對話框形式打開新窗口;
6. Response.Write("<script>window.showModelDialog('XXX.aspx')</script>")——對話框形式打開新窗口，原窗口被代替;
也可以自己寫方法：
復制代碼 代碼如下:
public static void ShowMessage(System.Web.UI.Page page, string msg)
{
    page.ClientScript.RegisterClientScriptBlock(page.GetType(), "a", "alert('" + msg.ToString() + "');", true);
}

調用的時候：
ShowMessage(this,"要顯示的消息");
下面是整個類的代碼你可以挑著用
復制代碼 代碼如下:

using System.Collections.Generic;
using System.Text;
