我正在做一个问答游戏，当玩家按字母顺序输入时，系统会将输入与正确答案进行比较。我使用一个数组来存储所有问题，系统应该从数组的第一个索引加载元素，即“F_L_A_S_H”，但它直接显示最后一个元素，谁能告诉我如何解决这个问题？

In displayQuestion you are assigning a value to answerArr. However, you are doing this in a for loop. This means that you iterate through all the elements and you change the value of that variable. That's why you get the latest answers directly.

正如 Krasimir 试图解释的那样，在“for”循环的最后一次迭代中，answerArr 被设置为仅包含 questionArr 数组中最后一项的拆分字母。您的其余代码永远不会看到 answerArr 包含除此之外的任何内容。我建议使用数组数组，以便 answerArr 数组的每个索引都包含一个由 questionArr 中的拆分字母组成的数组。因此，在 for 循环中：

answerArr.push(myStr.split("_"));

早些时候，您需要按如下方式声明 answerArr ...

 var answerArr:Array = new Array();

...因此它被定义为要“推送”到的 Array 对象。
