Question

嗨我正在制作一个我镇上的餐馆清单（因为我丈夫和我永远不能决定一个），看起来发电机只选择0-7（共有39个）。

到目前为止我没有看到任何问题所以我需要一双额外的眼睛。世界上我做错了什么？请帮忙！

Answer 1

将ar[sec % 7]更改为ar[sec % ar.length]。（＆＃34;请务必更新值＆＃39; 7＆＃39;在提醒框中＆＃34;应该是一个死的赠品 - 40将起作用而不是7，但{ {1}}不需要更新，因为它适用于任意数量的餐馆。）

BTW，不是错误，而是非常unJavaScripty：你创建数组的方式。它应该按原样运行，但很容易出错。我建议改变

ar.length

到

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

我的发电机不工作
