JavaScript的：如何加入/组合两个阵列连接成一个阵列？ [英] JavaScript: How to join / combine two arrays to concatenate into one array?

问题描述

我想在JavaScript 2阵列组合成一个。

  VAR线=新的Array（A，B，C）;
行=新的Array（D，E，F）;
 

这是一个简单的例子，我希望能够把它们结合在一起，这样，当第二行读取数组中的第4单元将返回D

我将如何做到这一点？

解决方案

  VAR一个= ['一'，'B'，'C'];
变种B = ['D'，'E'，'F'];
变种C = a.concat（B）; // C现在是一个数组：['一'，'B'，'C'，'D'，'E'，'F']
的console.log（三[3]）; // C [3]将D
 

I'm trying to combine 2 arrays in javascript into one.

var lines = new Array("a","b","c");
lines = new Array("d","e","f");

This is a quick example, i want to be able to combine them so that when the second line is read the 4th element in the array would return "d"

How would i do this?

解决方案

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
