JQuery拖放计数验证在表中的div中提交 [英] JQuery Drag and Drop Count Validation on Submit in Divs in a Table

问题描述

链接到JS Fiddle

我有一个表有div，在那些div我有图像，我想从第一列拖放到下两个列。这一点已经完成，但我想要发生的是，当用户单击完成时，它运行计数验证，以确保用户已将所有图像从第一列移动到下面两列。

I have a table that has divs, in those divs I have images that I would like to drag and drop from the first column into the next two columns. That bit has been done, but what I would like to happen is when the user clicks 'Finish' it runs a count validation to make sure the user has moved out all the images from the 1st column into the next two columns.

可以这样做吗？

<td><div class="options" id="option1" ondrop="drop(event)" ondragover="allowDrop(event)">

推荐答案

检查拖放的最佳方法之一是给参数 .options 当 .options 下降时，它会改变。在我的实现中，我使用 JQuery.data（）在 .options ： JSFiddle

The one of best way to check on drag and drop is to give parameter to .options which will change when the .options dropped. In my implementation, I use JQuery.data() to give parameter on .options, as you can see on here : JSFiddle
