获取与JavaScript中的最高值数组键 [英] Get the array key with the highest value in javascript

问题描述

我有一个像

arr[1] = 234;
arr[2] = 345;
...

arr[40] = 126;

我怎样才能获得最高价值的元素的索引，而不重申阵列？

How can I get the index of the element with the highest value without reiterating the array?

推荐答案

您可以申请Math.max和传递数组作为参数 -

You can apply Math.max and pass the array as its arguments-

arr.indexOf(Math.max.apply(window,arr))

但现在Math.max是做迭代，就像那种会做。

But now Math.max is doing the iterating, just as sort would do.

有人有看每个项目在排序的数组...
