There is no alert in the code you linked to. Javascript won't magically decide to display an alert on its own; you need to tell it what to display and when.

if ( correctCards == 6 )
{
$('#successMessage').show();
$('#successMessage').animate( {
left: '380px',
top: '200px',
width: '400px',
height: '100px',
opacity: 1
} );
}

is the function which should do that

That's not an alert call; that's showing an element using jQuery.

You have a script error in the console - your second for loop is iterating past the end of the numbers array.

And your if (correctCards == 6) test is outside of your handleDropEvent method, so it only runs once, when the page first loads.

Your android and science variables are looking for data items called N and H. But the code that creates the elements set a data item called number. And one of them is set to the index, whereas one is set to the letter.

But the biggest problem is that there is no element in the document with the ID successMessage.
