我位于已加载的<iframe>产品的底部，您想要将个人<div>拖到屏幕顶部。在顶部，根据需要，框架大小的图片将是1到5 <div> s和背景右框架。
当您完成向框架添加产品并单击按键或鼠标按钮以跳转到购物篮和完成订单时。
请帮忙走哪条路。 jQuery UI或Mootools？这是最简单的方法。

尝试修改此页面中的代码。它基于移动DIV，但只需更改DROP功能即可根据您的要求进行修改。请注意，您显示的示例并不理想，因为它不会突出显示允许放置对象的位置，而这一点可以。

<div id="box1" class="box"></div>
<div id="box2" class="box"></div>
<div id="dragApp" class="obj">This one appends to either box.</div>
<div id="dragAny" class="obj"><div class="closeBox" onclick="closeBox(this.parentNode);return false;">X</div>This one can be dragged anywhere.</div>
<div id="dragBox" class="obj">This one can only go in the top box.</div>
<p>I decided to look into HTML5 drag and drop. I found several examples online, but none seemed to
provide any validation of where the items were being dragged except when they were actually dropped.
So I created this page as an example of how to do it.</p>
<div id="dragFlt" class="obj"><div class="closeBox" onclick="closeBox(this.parentNode);return false;">X</div>This float goes in the bottom box.</div>
<p>Note that the example built into this page won't work in IE9 as I've set DIV elements to drag,
but IE9 only supports IMG and A-HREF elements.</p>
<p>I wrapped the whole thing in a setDrag function that takes in the ids of the object to be dragged
and the location where it can be dropped. If the drop is to be completed by appending the object as a
child then a third argument should be set to true.</p>
<p>There are seven events involved in dragging and dropping:</p>
<pre>
object dragstart when object first moved
drag while object is being moved
dragend when the object is dropped
target dragenter when object enters the target
dragover while object is over the target
dragleave when object leaves the target
drop when the object is dropped
</pre>
<p>The dragstart/dragend events are useful for changing the object appearance, and for initialling the
cursor types and obect data in dataTransfer. The drag event isn't used here.</p>
<p>I don't use the dragenter/dragleave events. The drop event is the one that handles the moving of the
object by changing its position/DOM location. The key is the dragover event as this determines where a
drop can actually be made. The default is to not allow a drop so unless it performs a stopDefault() then
no drop will be allowed.</p>
<br>
<p>There are some <b>gotchas:</b></p>
<p>In IE dragover can't use either THIS or dataTransfer to access the object info. So to get the id of
the object in dragover you need to set a variable in dragstart.</p>
<p>In object events you can use event.target for the object (same as THIS) but in target events you have
to use event.currentTarget (same as THIS) instead.</p>
<p>FF doesn't need to initialise the effectAllowed but IE does. I'm not use if setting the cursor to 'none'
is required or not.</p>
<p>Because of event bubbling (I think) you still need to validate the combination of object/target in the
drop event.</p>
