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?

No, you can't.

It's a security/anti-phishing feature.

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.)

I had a similar issue when I wanted to change the box title and button title of the default confirm box. I have gone for the Jquery Ui dialog plugin http://jqueryui.com/dialog/#modal-confirmation

When I had the following: 

function testConfirm() {
  if (confirm("Are you sure you want to delete?")) {
    //some stuff
  }
}

I have changed it to:

function testConfirm() {

  var $dialog = $('<div></div>')
    .html("Are you sure you want to delete?")
    .dialog({
      resizable: false,
      title: "Confirm Deletion",
      modal: true,
      buttons: {
        Cancel: function() {
          $(this).dialog("close");
        },
        "Delete": function() {
          //some stuff
          $(this).dialog("close");
        }
      }
    });

  $dialog.dialog('open');
}

Can be seen working here https://jsfiddle.net/5aua4wss/2/

Hope that helps.
