代码背后的警报消息框 [英] Alert Message Box From Code Behind

问题描述

大家好。我有一个带有电子邮件功能的网页。一切正常但是一旦发送了电子邮件，我想在用户点击提交后显示警告框并且电子邮件已成功发送...我该如何做到这一点？我尝试使用此代码...

  string  cleanMessage = messagge .Replace（ '，  \\'）; 
  string  script =  <脚本类型= \text / javascript \> alert（' + cleanMessage +  '） ;< /脚本>中; 
 
 Page page = HttpContext.Current.CurrentHandler  as  Page; 
 
  if （page！=  null &&！page.ClientScript .IsClientScriptBlockRegistered（  alert））
 {
 page.ClientScript.RegisterClientScriptBlock （page.GetType（），  alert，脚本）; 
} 

但没有警报框播放器。任何帮助将不胜感激，请提前感谢。

解决方案

此代码将帮助您显示客户端信息框。

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

您可以在电子邮件发送过程后使用，例如;

示例用法

 SmtpClient _Mail =  new  SmtpClient（）; 
 Mail.Send（mailMessage）; 
 MessageBox（ 电子邮件已成功发送。）; 

祝你好运，

写这个

 StringBuilder result =  new  StringBuilder（）; 
 result.Append（ < script type = \   text / javascript \ >  { ）; 
 result.Append（ alert（' + cleanMessage +' ）;} result.Append（  script>）; 
 ClientScript.RegisterClientScriptBlock（< span class =code-keyword> this  .GetType（），  result ，result.ToString（））; 

试试这个

 Response.Write（< span class =code-string> @ < script language ='javascript'> alert（'Mail sent successfully。'）;< / script> ）; 

或者，如果您使用的是更新面板，请尝试使用此面板..

 ScriptManager.RegisterStartupScript（ this ，GetType（）， < span class =code-string> startprocesskey，   alert（'Mail sent successfully。'）， true ）; 

Hi all. I have a webpage with an email function. Everything works but once the email has been sent, I want an alert box to appear after the user clicks submit and the email has been successfully sent...How can i accomplish this? i tried using this code...

string cleanMessage = messagge.Replace("'", "\\'");
string script = "<script type=\"text/javascript\">alert('" + cleanMessage + "');</script>";

Page page = HttpContext.Current.CurrentHandler as Page;

if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert"))
        {
         page.ClientScript.RegisterClientScriptBlock(page.GetType(), "alert", script);
        }

but no alert box appaers. Any help would be much appreciated, thanking you in advance.

解决方案

This code will help you show a client sided messagebox.

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

You can use after your email send process such as;
example usage

SmtpClient _Mail = new SmtpClient();
Mail.Send(mailMessage);
MessageBox("Email has been sent successfully.");

Good luck,

Write this

StringBuilder result = new StringBuilder();
            result.Append("<script type="\"text/javascript\"">  {");
            result.Append("alert('" + cleanMessage + "');}            result.Append("script>");
            ClientScript.RegisterClientScriptBlock(this.GetType(), "result", result.ToString());

Try this one

Response.Write(@"<script language='javascript'>alert('Mail sent successfully.');</script>");

Or, if you are using Update panel then try this one..

ScriptManager.RegisterStartupScript(this, GetType(), "startprocesskey", "alert('Mail sent successfully.')", true);
