javascript - jquery UI sortable检测上下轴

Question

我很难检测 N 轴是向上还是向下移动？而且我还想要里面的物体(h2 和 p)，留在原位。有人可以帮忙吗!

<div class="ss-zone-object" style="top: 68px; width:300px; height: 500px; left: 20px;">
    <h2 style="top: 100px; width: 60px;">Title</h2>
    <p style="left: 122px; top: 120px; width: 60px;">Summary</p>
</div>

 $(function () {
    $('.ss-zone-object').resizable({
        grid: [1, 1],
        handles: 'n,s',
        resize: function (e, ui) {
            var handle_axis = $(this).data('ui-resizable').axis;

            $(this).find('h2, p').each(function (mk, mv) {

                var obj_top = parseInt($(this).position().top);
                if (handle_axis === 'n') { // Axis N, moving down then minus one
                    $(this).css('top', (obj_top - 1) + 'px');
                } else if (handle_axis === 's') {

                }
            });

        },
        stop: function (e, ui) {}
    });
});

好的，例如，这是:

$(function () {
    var s = $('h2').position().top;
    var p = $('h2').position().top;
    var height_font_s = 68; // define manual
    var height_font_p = 88; // define manual
    $('.ss-zone-object').resizable({
        grid: [1, 1],
        handles: 'n,s',
        resize: function (e, ui) {
            var handle_axis = $(this).data('ui-resizable').axis;
            var t = $('.ss-zone-object').position().top;
            $(this).find('h2').css('top', (-(t-(s+height_font_s)))+'px');
            $(this).find('p').css('top', (-(t-(p+height_font_p)))+'px');
        },
        stop: function (e, ui) {}
    });

})

.ss-zone-object {
    background-color: #ccc;
    position:absolute;
}
.ss-zone-object h2, .ss-zone-object p {
    position:absolute;
}
