how to replace javascript alerts with a modal box?

The javascript alerts are triggered through an echo depending on some database results

if response is a
{
     <script type="text/javascript">alert("response is a.");</script>
}
else
{
    <script type="text/javascript">alert("response is not a.");</script>
}

I am using bootstrap, if we can replace the alerts with bootstrap modal its perfect

Took the liberty of creating a jsbin example for you, based on the code you can find in the following question: JavaScript: Overriding alert()

http://jsbin.com/UzUDOno/1/edit

Do note that overriding alert may not be a great idea, especially because you'll be missing out on the blocking properties of regular javascript alerts. As you can see in my example, if you use 2 alerts in quick succession, the last one will override the one(s) before that.

    modal.find(".modal-body").text(arguments[0]);
    modal.modal('show');
  };
})();


    alert('moo');
    alert('cow');
  </script>
</body>
</html>

"Your jsbin example shows a call for alert('moo') followed by alert('cow')"

My example show both 'moo' and 'cow'.
