jQuery mobile: How to invoke this (default) error loading page message?

Question

I am building RESTful mobile app and I like the default behaviour when resource is not found. jQuery Mobile shows this:

Answer 1

//show error message
$( "
YOUR MESSAGE
" )
  .css({ "display": "block", "opacity": 0.96, "top": $(window).scrollTop() + 100 })
  .appendTo( $.mobile.pageContainer )
  .delay( 800 )
  .fadeOut( 400, function() {
    $( this ).remove();
  });
