创建多个dimesion数组

Question

我需要这样的东西:

var fruits[1] = ["Banana", "Orange", "Apple", "Mango"];
fruits[2] = ["Banana"];
fruits[1].push("Lemon");
fruits[2].push("Orange");

但这不适用于javascript.

有没有办法在javascript中实现这种机制？

Answer 1

首先,将fruits自身初始化为数组

var fruits = [];
fruits[1] = ["Banana", "Orange", "Apple", "Mango"];
fruits[2] = ["Banana"];
fruits[1].push("Lemon");
fruits[2].push("Orange");

console.log(fruits);
