嗨，我正在生成我镇上的餐馆列表(因为我和我丈夫永远无法决定其中一家)，看起来生成器只在 0-7 之间进行选择(总共 39 家)。

到目前为止我还没有发现任何问题，所以我需要一双额外的眼睛。我到底做错了什么？请帮忙!

最佳答案

将ar[sec % 7]更改为ar[sec % ar.length]。 (“确保更新警报框中的值“7””应该是一个致命的赠品 - 40 可以代替 7，但是 ar. length 使得不需要更新，因为它适用于任意数量的餐厅。)

顺便说一句，不是错误，但非常不JavaScripty:创建数组的方式。它应该按原样工作，但是很容易出错。我建议改变

var ar = new Array(40)
ar[0] = "Painted Horse"
ar[1] = "Indian Coffee Co"
//...

进入

var ar = [
  "Painted Horse",
  "Indian Coffee Co",
  //...
];
