animate.gif
如上面的gif图所示，可以在输入框中，输入要产生的动画的数量，然后点击click me按钮，就产生了效果。产生的效果是通过在数组中预设的几种。这里为了演示方便，没有设置具体的形状，比如可以更换为一些其它的iconfont来实现效果。<p>
具体思路：通过<code>$.queue</code>和<code>$.dequeue</code>来实现动画队列的存取与取出实现效果。首先通过按照<code>input</code>输入的数字来形成对应数量效果对象的数组。然后在把数组存放到<code>$.queue</code>中，最后通过click me按钮触发，一个一个取出动画序列，实现动画。<p>
注意：这里要注意的是，在一个一个取出动画的时候，用到了<code>setInterval</code>，不需要的时候一定要清除计时器，否则会影响序列，不停的取出。
