Drag and insert div into another div
提问by user2640254
I am trying to design a feature that could drag and insert one div into another div.
我正在尝试设计一种可以将一个 div 拖动并插入另一个 div 的功能。
For example:
例如：
<div id="1"> </div>
<div id="2"> </div>
<div id="1"> </div>
<div id="2"> </div>
i want to make #1 draggable (I know it can be done with jQuery, so draggable is not part of my question), and drag #1 over #2, and when mouseup, #2 could be inserted into #1
我想让 #1 可拖动（我知道它可以用 jQuery 完成，所以可拖动不是我的问题的一部分），并将 #1 拖到 #2 上，当鼠标悬停时，#2 可以插入 #1
<div id="1"> <div id="2"> </div> </div>
could somebody explain to me how to achieve that?
有人可以向我解释如何实现这一目标吗？

You could simplify this quite a bit by using jQuery UI's Sortable
您可以通过使用jQuery UI 的 Sortable来简化这一点
$(document).ready(function () {
addElements();
$(function () {
$("#list1, #list2").sortable({
connectWith: ".lists",
cursor: "move"
}).disableSelection();
});
});
function addElements() {
$("#list1").empty().append(
"<li id='item1' class='list1Items'>Item 1</li>" +
"<li id='item2' class='list1Items'>Item 2</li>" +
"<li id='item3' class='list1Items'>Item 3</li>");
}
