到达数据对象末尾时停止迭代
问题描述：
使用 TweenMax 库，当到达数据对象的末尾而不是循环时，我无法杀死或停止delayedCall，因为它是自调用函数.
Using the TweenMax library, I am unable to kill or stop a delayedCall when the end of the data object is reached instead of looping because it is a self calling function.

在上面的示例中，数据的最后一项没有显示.
In the example above the last item in the data is not displayed.
答
实际上是因为您在设置iter变量之前先对其进行了递增.这会导致它不显示最后一项，而您要在之后增加:
Actually it's because you are incrementing your iter variable before you set it. Which causes it to not display the last item, you want to increment after:
function setContent() {
element.html(data[iter].content);
iter = iter >= data.length-1 ? -1 : iter;
iter = iter + 1;
}
基本上，当您要遍历[0,1,2]时，您正在遍历索引[1,2,3].
Basically you are going over indexes [1,2,3] when you want to be going over [0,1,2].
