我正在尝试使用JavaScript为学校项目创建一个魔法8球，但是当尝试声明var questionting = document.getElementById('wagwan').value;时，变量在调用输出时不会返回任何类型的任何值（参见图像）。我花了一些时间试图解决这个问题，但是我找不到能够解决问题的解决方案。

Answer 1

var questionting    = document.getElementById('wagwan').value;

将它放入dosomething（） - 方法并再试一次。

document.getElementById（）。作为变量的值将不起作用
