javascript - 如何返回属性名称？

Question

我不太确定该怎么做，或者用谷歌搜索什么来找到答案......

for (var c in cfd){
   if (cfd[c] <= cfd[c+1]) {
       nextfunk = ???
   }
}

在 for 循环之后，我希望 nextfunk 具有最低值 cfd 的名称的值。

谢谢。

   if (cfd[c] <= cfd[c+1]) {
       nextfunk = c;
   }
}

既然你要求退货：

var nextfunk;

for (var c in cfd){
   if (cfd[c] <= cfd[c+1]) {
       nextfunk = c;
   }
}

return nextfunk;
