title: How to change the title of javascript alert box in asp.net?
body: <p>In ASP.Net I am using an <code>ImageButton</code> on click of which I am showing <code>JavaScript</code> <code>confirm</code> button like below:</p>
  
  <pre><code>&lt;asp:ImageButton ID="imageButtonDelete" ImageUrl="~/Styles/images/delete.png" CommandArgument='&lt;%#Eval("regionId") %&gt;' OnClientClick="javascript:return confirm('Are you sure you want to delete?');" Text="Delete" CommandName="Delete" runat="server" Width="20px" Height="20px" /&gt;
  </code></pre>
  
  <p>However, in Chrome, the title of the alert box shows -</p>
  
  <blockquote>
    <p>the page at localhost:1150 says</p>
  </blockquote>
  
  <p>I don't want <code>the page at...</code> text. How to change that?</p>
