window.close()无法正常工作

本文介绍了window.close()无法正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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

推荐答案

如果可以的话请尝试... 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()); } } }
