var date = ' <?php echo $new_date; ?>';
$('.custom_checkbox').click(function() {
pressed = true;
var prev = $(this).attr('class');
var arrid = $(this).attr('id');
var seats = $(this).attr('title');
count = $('.selected').length;

//}
} else {
alert("Seat already been used.Please select another");
}
}
})
}
});
});

Answer 1

You need to configure you're Ajax with "async:false" ,because there is a Race Condition thing ,so block the code while you're manipulating Array's.
Se this question.

Answer 2

The AJAX call you are making is asynchronous (by definition...), meaning that the actual function you are defining in $('.custom_checkbox').click is already finished before the success function is called...
When you click on the next div (e.g. div 2) then the success function of the first click may or may not have already been called...
Could this be the problem?
