How to edit a JavaScript alert box title?

Question

Hi, I'm generating a JavaScript alert with following code in C# .NET page:

Response.Write("<script language=JavaScript> alert('Hi select a valid date'); </script>");

It displays an alert box with the heading title as "Message from webpage".

Is it possible to modify the title?

Answer 1

No, it is not possible. You can use a custom javascript alert box.

Found a nice one using jQuery

jQuery Alert Dialogs (Alert, Confirm, & Prompt Replacements)

Answer 2

You can do this in IE:

<script language="VBScript">
Sub myAlert(title, content)
      MsgBox content, 0, title
End Sub
</script>

<script type="text/javascript">
myAlert("My custom title", "Some content");
</script>

(Although, I really wish you couldn't.)

Answer 3

Sigh...no you can't

Answer 4

To answer the questions in terms of how you asked it.

This is actually REALLY easy, i did it in like 17.5 seconds.

If you use the custom script that cxfx provided: (place it in your apsx file)

<script language="VBScript">
Sub myAlert(title, content)
MsgBox content, 0, title 
End Sub 
</script>

You can then call it just like you called the regular alert. Just modify your code to the following.

Response.Write("<script language=JavaScript> myAlert('Message Header Here','Hi select a valid date'); </script>");

Hope that helps you, or someone else!
