如何在asp.net中显示msgbox？ [英] How to display msgbox in asp.net?

问题描述

如何使用C＃在asp.net中显示msgbox？

我无法使用windows.msgbox

它可以通过，

 Response.Write（< script> alert（''Item Already Exists''）< / script>）; 

但我面临的问题是，当显示msgbox时，实际网页变为空白（即全白），点击确定后，我又回到了页面。有没有办法同时显示msgbox和页面？

解决方案

试试：

 ClientScript.RegisterStartupScript（this.GetType（），myalert，alert（''+ myStringVariable +''）;，true）;

干杯

你无法执行Response.Write，因为它会清除内容并将响应作为你在Write方法中发送的内容。



相反，假设您在asp.net页面中有一个按钮，并且单击要从C＃显示消息框的按钮，然后，您可以执行此操作o n C中的按钮点击事件＃

  string  javaScript =   alert（'Item Already Exists'）;; 
 
 
 Page.ClientScript.RegisterStartupScript（ this  .GetType（），  ButtonClickEventScript，javaScript， true ）;

How to display a msgbox in asp.net using C#?
I can''t do it using windows.msgbox
It can be done by,

Response.Write("<script>alert(''Item Already Exists'')</script>");

But the problem I am facing is that, when the msgbox is being displayed, the actual webpage turns blank (i.e. full white), and on clicking OK, I am getting back the page again. Is there any way to display the msgbox as well as the page at the same time?

解决方案

Well try with:

ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert(''" + myStringVariable + "'');", true);

You cant do Response.Write since it wipes out the content and put the response as what you are sending inside the Write method.

Instead lets say you have a button in your asp.net page and on click of the button you want to show the message box from C# then,You can do this on the button click event in C#

string javaScript = "alert('Item Already Exists');";


          Page.ClientScript.RegisterStartupScript(this.GetType(),"ButtonClickEventScript", javaScript,true);
