Original answer

Already answered but since I had an answer, I’m going to post it anyway…

$('#dialog').dialog({
    show: {
        effect: 'slide',
        complete: function() {
            console.log('animation complete');
        }
    },
    open: function(event, ui) {
        console.log('open');
    }
});

Shows open followed by animation complete in the Console
