在JavaScript中合并两个数组 [英] Combine two arrays in JavaScript

问题描述

我可以像这样在JavaScript中合并两个数组吗?

Can I merge two arrays in JavaScript like this?

这些数组:

arr1 = ['one','two','three'];
arr2 = [1,2,3];

进入

arr3 = ['one': 1, 'two': 2, 'three' : 3]

推荐答案

var arr3 = {};
for (var i = 0; i < arr1.length; i++) {
    arr3[arr1[i]] = arr2[i];
}

请注意，arr3不是数组，它是对象.

Please note that arr3 is not array, it is object.
