本文介绍了递归地反转数组中的元素的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想在javascript中编写一个递归函数，该函数返回一个数组，其元素反转.这段代码会产生以下错误:

I want to write a recursive function in javascript that returns an array with its elements reversed. This code generates the following error:

未定义不是函数

function reverseArray (toBeReversed){ var reversed = []; function reverser (toBeReversed){ if (toBeReversed.length == 1) reversed.push(toBeReversed[0]); else { reversed.push(toBeReversed.lastOfIndex(0)); //error on this line reverser(toBeReversed.slice(-1)); } } reverser(toBeReversed); return reversed; }

推荐答案

lastOfIndex不是一个函数，您可能希望使用lastIndexOf.这是类似的方法:

lastOfIndex is not a function, you probably mean to use lastIndexOf. here is a similar way:

function reverseArray (toBeReversed){ var reversed = []; function reverser (toBeReversed){ if (toBeReversed.length !== 0){ reversed.push( toBeReversed.pop() ); reverser( toBeReversed ); } } reverser(toBeReversed); return reversed; }
