javascript - 以编程方式用数组填充数组

这是通过for循环并使用sims创建名为str1的数组数组的代码。

到目前为止，我需要手动定义sims的长度，等于str1的长度，例如:let sims = [[],[],[],[]];(四个数组，等于str1上的四个单词)

如何以编程方式用数组填充模拟人生？

var str1 = "do you ever looked";
var str2 = "do you fr ever looked";

let sims = [[],[],[],[]]; // instead I want let sims = [];

let s1 = str1.split(" ")
let s2 = str2.split(" ")

for (var j = 0; j < s1.length; j++) {
  for (var i = 0; i < s2.length; i++) {
    sims[j].push(s1[j].toString());
  }
}

console.log(sims);

最佳答案

在initializing之前先对数组进行pushing

sims[j] = [];

var str1 = "do you ever looked";
var str2 = "do you fr ever looked";

let sims = [];

let s1 = str1.split(" ")
let s2 = str2.split(" ")

for (var j = 0; j < s1.length; j++) {
  sims[j] = [];
  for (var i = 0; i < s2.length; i++) {
    sims[j].push(s1[j].toString());
  }
}

console.log(sims);
