推荐答案

也许晚了3年，但您可以调度事件并使用以下代码片段来获得预期的行为:

Maybe 3 years too late but you could dispatch event and use following snippet for a more expected behaviour:

演示jsFiddle

$(".draggable").draggable({
    start: function (event, ui) {
        $(this).data('preventBehaviour', true);
    }
});
$(".draggable").find(":input").on('mousedown', function (e) {
    var mdown = new MouseEvent("mousedown", {
        screenX: e.screenX,
        screenY: e.screenY,
        clientX: e.clientX,
        clientY: e.clientY,
        view: window
    });
    $(this).closest('.draggable')[0].dispatchEvent(mdown);
}).on('click', function (e) {
    var $draggable = $(this).closest('.draggable');
    if ($draggable.data("preventBehaviour")) {
        e.preventDefault();
        $draggable.data("preventBehaviour", false)
    }
});
