试图以相同的方式在JavaScript中随机播放多个数组？

问题描述：

我想在同一个函数中随机地随机排列这两个数组

I want to randomly shuffle these two arrays in the same function

var array1 = [1,2,3,4,5];
var array2 = [6,7,8,9,10];

因此它返回随机重组的每个数组，例如

So that it returns each array randomly shuffled such as

4,2,3,5,1
7,9,6,8,10

还返回时，我想在两者之间换行，请帮忙？

Also on return I want a line break between the two, please help?

答

在 Array.prototype 中添加了shuffle方法以便于访问-返回修改后的数组，使原始数组保持不变。

Added shuffle method to Array.prototype for easy access - returns a modified array keeping the original unchanged.

Array.prototype.shuffle = function() {
  var rIndex, temp,
    input = this.slice(0),
    cnt = this.length;

  while (cnt) {
    rIndex = Math.floor(Math.random() * cnt);
    temp = input[cnt - 1];
    input[cnt - 1] = input[rIndex];
    input[rIndex] = temp;
    cnt--;
  }

  return input;
}

var array1 = [1, 2, 3, 4, 5];
var array2 = [6, 7, 8, 9, 10];

document.getElementById('shuffle-btn').onclick = function(){
  document.getElementById('output').innerHTML = [array1.shuffle(), array2.shuffle()].join('\n');
}

<button id="shuffle-btn">Shuffle</button>
<pre id="output"></pre>
