Create the error div in modal body. and set error

$(document).ready(function(){
  $('#alertbox').click(function(){
    $("#error").html("You Clicked on Click here Button");
      $('#myModal').modal("show");
    });

Answer

Probably I didn't understood your question correctly, but you can't use the alert function to display a message insidea a page element. Alert displays a system alert outside the page dom.

If you want to display a message inside a modal you have to include (or inject) the modal markup in your page html, then you simply show/hide the modal via bootstrap functions.

You have a very good example here
