在JS中组合数组 [英] Combining arrays in JS

问题描述

如果您有2个经典和流行阵列：

If you have 2 arrays classical and pop:

classical=["Beethoven","Mozart","Tchaikovsky"];
pop=["Beatles","Corrs","Fleetwood Mac","Status Quo"];

为什么设置 all = classical + pop 它给数组元素中的字符设置一个单独的字符吗？

Why is that when you set all=classical+pop it gives sets character in the array elements an individual character?

如何在不重新输入的情况下纠正这一点，即 all = [Beethoven ，莫扎特，柴可夫斯基，甲壳虫乐队......]

How do you correct this without retyping i.e. all=["Beethoven","Mozart","Tchaikovsky","Beatles"...]

非常感谢提前。

推荐答案

使用Array类的concat（）方法将它们组合在一个新变量上：

Use the Array class concat() method to combine them on a new variable:

var all = classical.concat(pop);
