我不是很明白你的问题，但我会进行有根据的猜测......

您需要将您的逻辑包装在“确认”IF 语句中。此外，您还有一个额外的“}”)。

$(document).ready(function(){

    $('.del_btn').click(function() {

        if (confirm("Are you sure you want to delete this Color?")) {

            var del_id = $(this).attr('rel');

            $.post('script/delete_color.php', {delete_id:del_id}, function(data) {

                if(data == 'true') {
                    $('#'+del_id).remove();alert('Color has been deleted!');
                } else {
                    alert('Color could not delete!');
                }

                document.messages.submit();
                return false; // This line added
            }
        }
    });
});
