Jquery UI可排序，自动移动项目 [英] Jquery UI Sortable, move item automatically

问题描述

我有两个可排序的链表，称为列表1和列表2.

I have two sortable linked lists, call them list 1 and list 2.

列表1是用户可以选择的所有可能项目的列表将它们拖入他的购物篮，即列表2.

List 1 is a list of all the possible items that a user may choose and he drags them into his shopping basket which is list 2.

我想要做的是在列表2中的每个项目旁边有一个按钮（或链接）（购物篮）当点击时将项目移回列表1而用户实际上不必将其拖动到那里。

What I would like to do is to have a button(or link) next to each item in list 2(The shopping basket) that when clicked moves the item back into list 1 without the user actually having to drag it there.

我知道我可以通过简单地使用remove来轻松实现这一点（ ）从列表2中删除项目，然后使用append（）或after（）等将其添加回列表1但我希望动画可以动画。

I know I can easily achieve this by simply using remove() to remove the item from list 2 and then using append() or after() etc to add it back into list 1 but I would like the movement to be animated.

有没有办法实现这一点，以便项目自动从一个列表拖动到另一个列表？如果是这样的话？

Is there a way that I can achieve this so that the item is automatically "dragged" from one list to the other? and if so how?

我已经好好看看但无济于事，但如果可以的话，该网站会好得多。因此，非常感谢您提供的任何帮助。
谢谢。

I've had a good look around but to no avail, but the site would be much better if I could. Therefore any help you can offer would be greatly appreciated. Thanks.

推荐答案

好的，我想出了答案，所以我想问我应该把问题放到回答这里，以帮助其他需要知道的人。

Ok, I figured out the answer and so thought since I asked the question I should put the answer up here to help anyone else who needs to know.

我有点愚蠢，想通过jquery ui来做这件事，因为我的列表可以排序是无关紧要的，我只需要使用jquery来移动元素并为其设置动画。

I was being a bit stupid looking for a way to do it through jquery ui as the fact my lists were sortable was irrelevant, I just needed to user jquery to move the element and animate it.

下面的函数非常有用：

function moveAnimate(element, newParent){
    var oldOffset = element.offset();
    element.appendTo(newParent);
    var newOffset = element.offset();

    var temp = element.clone().appendTo('body');
    temp    .css('position', 'absolute')
            .css('left', oldOffset.left)
            .css('top', oldOffset.top)
            .css('zIndex', 1000);
    element.hide();
    temp.animate( {'top': newOffset.top, 'left':newOffset.left}, 'slow', function(){
       element.show();
       temp.remove();
    });
}
