尝试提醒 which.style.display 的初始值。

我添加了alert（which.style.display）;到功能的开头。


我第一次点击它时，警报中没有任何内容。第二次说阻止。

Try alerting the initial value of which.style.display.

I added alert(which.style.display); to the beginning of the function.

The first time I click it, there''s nothing in the alert. The second time it says block.
