在jQuery中将类添加到正文不起作用

Question

我有三个带有随机选择的图像和数组项的类框。右下方有一个正方形box002，可以将其拖放到三个方框中的任何一个上。如果找到匹配项，则该框将消失，同样，第三个框也将消失。

然后将名为bodyblue的类添加到正文，并将名为middle bg的backgroundImage添加到正文10秒钟。再次出现三个框，以进行拖放。

我遇到的问题是：

在第二个级别中，将三个框拖放并删除后，将bodyblue添加到主体后，backgroundImage中间bg不会出现10秒钟。

如何在第二级和第三级使用jquery将bodyblue backgroundImage添加到正文？
