Javascript 在JS中组合数组

如果您有两个数组：古典和流行：

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

为什么当您设置

all=classic+pop

时，数组元素中的set字符会有一个单独的字符

如何在不重新键入的情况下更正此问题，即

all=[“贝多芬”、“莫扎特”、“柴可夫斯基”、“披头士”…]

非常感谢。

+

首先将两个数组转换为字符串，然后添加字符串。为此，您需要使用

concat

方法

> classical=["Beethoven","Mozart","Tchaikovsky"];
["Beethoven", "Mozart", "Tchaikovsky"]
> pop=["Beatles","Corrs","Fleetwood Mac","Status Quo"];
["Beatles", "Corrs", "Fleetwood Mac", "Status Quo"]
> all = classical.concat(pop)
["Beethoven", "Mozart", "Tchaikovsky", "Beatles", "Corrs", "Fleetwood Mac", "Status Quo"]

使用数组类concat（）方法将它们组合到一个新变量上：

var all = classical.concat(pop);
