window.close()无法正常工作 [英] window.close() is not working

问题描述

我的弹出窗口中有一个按钮.单击该按钮时，它会处理某些方法并检查该过程是否成功完成.如果是这样，它将在消息框中通知用户.此meesagebox是一个JavaScript代码，alert()方法.在仍然处于按钮单击过程中之后，我还有另一个javascript代码正在刷新主页，并且我试图关闭弹出窗口.

我的代码是:

I have button in my popup. When the button is clicked it processes some methods and checks if the process is successfully completed. If so, on a messagebox it notifies the user. This meesagebox is a javascript code, alert() method. After that still inside button click process I have another javascript code which is refreshing the main page and I am trying to close the popup window.

My code is:

protected void btnMyButton_Click(object sender, EventArgs e)
{
  MessageBox("Parts are successfully grouped!");
  BindGridView(ddlParts.SelectedValue);
  string scriptString = "<script language='JavaScript'>window.opener.document.forms(0).submit();window.close();</script>";                    
  if (!Page.ClientScript.IsClientScriptBlockRegistered(scriptString))
  {
    Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", scriptString);
  }                      
}

private void MessageBox(string msg)
{
  Page.Controls.Add(new LiteralControl("<script language='javascript'> window.alert('" + msg.Replace("'", "\\'") + "')</script>"));
}

因此，当我评论消息框"行时，主页将被刷新，弹出窗口被关闭.但是，如果我不对消息框行进行注释，则会出现该消息框，刷新主页面，但不会关闭弹出窗口.

有没有办法显示消息框并关闭弹出窗口?谢谢大家

So when I comment the Messagebox line the main page is getting refreshed and popup gets closed. But if i keep the messagebox line uncommented the message box appears, the main page gets refreshed but the popup window will not close.

Is there a way to show the messagebox, and close the popup window? thank you all

Hi,
try this if could help...

MessageBox.Show(this, "Parts are successfully grouped!");

public class MessageBox
   {
       private static Hashtable m_executingPages = new Hashtable();
       private MessageBox() { }
       public static void Show(string sMessage)
       {
           // If this is the first time a page has called this method then
           if (!m_executingPages.Contains(HttpContext.Current.Handler))
           {
               // Attempt to cast HttpHandler as a Page.
               Page executingPage = HttpContext.Current.Handler as Page;
               if (executingPage != null)
               {
                   // Create a Queue to hold one or more messages.
                   Queue messageQueue = new Queue();
                   // Add our message to the Queue
                   messageQueue.Enqueue(sMessage);
                   // Add our message queue to the hash table. Use our page reference
                   // (IHttpHandler) as the key.
                   m_executingPages.Add(HttpContext.Current.Handler, messageQueue);
                   // Wire up Unload event so that we can inject
                   // some JavaScript for the alerts.
                   executingPage.Unload += new EventHandler(ExecutingPage_Unload);
               }
           }
           else
           {
               // If were here then the method has allready been
               // called from the executing Page.
               // We have allready created a message queue and stored a
               // reference to it in our hastable.
               Queue queue = (Queue)m_executingPages[HttpContext.Current.Handler];
               // Add our message to the Queue
               queue.Enqueue(sMessage);
           }
       }
       public static void Show(System.Web.UI.Page page, string msg)
       {
           ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "clientScript", "javascript:alert('" + msg + "');", true);
       }

       // Our page has finished rendering so lets output the
       // JavaScript to produce the alert's
       private static void ExecutingPage_Unload(object sender, EventArgs e)
       {
           // Get our message queue from the hashtable
           Queue queue = (Queue)m_executingPages[HttpContext.Current.Handler];
           if (queue != null)
           {
               StringBuilder sb = new StringBuilder();
               // How many messages have been registered?
               int iMsgCount = queue.Count;
               // Use StringBuilder to build up our client slide JavaScript.
               sb.Append("<script language='javascript'>");
               // Loop round registered messages
               string sMsg;
               while (iMsgCount-- > 0)
               {
                   sMsg = (string)queue.Dequeue();
                   sMsg = sMsg.Replace("\n", "\\n");
                   sMsg = sMsg.Replace("\"", "'");
                   sb.Append(@"alert( """ + sMsg + @""" );");
               }
               // Close our JS
               sb.Append(@"</script>");
               // Were done, so remove our page reference from the hashtable
               m_executingPages.Remove(HttpContext.Current.Handler);
               // Write the JavaScript to the end of the response stream.
               HttpContext.Current.Response.Write(sb.ToString());
           }
       }
   }
