问题描述
我正在尝试将一个处理程序绑定到一个事件。事件是一个键控功能。处理程序将侦听命中变量以产生两个条件之一。第一个条件（奇数点击）将执行1个功能，第二个（偶数次命中）将执行另一个功能。要详细说明，第一个功能将滚动到一个元素，第二个将滚动到另一个元素
I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element
以上是一个演示的链接，您可以看到一个讨厌的错误。
Above is a link to a demo, there is a nasty bug which you can see.
唯一可以想到的是，第二个事件应修改以下内容：
The only thing I can think of is that the following should be revised for the second event:
.offset().top
推荐答案
声明命中在您的keydown功能之外，因此每次不会重置为0。
declare hits outside your keydown function so it doesn't get reset to 0 each time.
