使用排序方法和数学方法：

var arr =  ["HORSE", "TIGER", "DOG", "CAT"];
function shuffleArray(arr){
  return arr.sort( () => Math.floor(Math.random() * Math.floor(3)) - 1)  
}

// every time it gives random sequence
shuffleArr(arr);
// ["DOG", "CAT", "TIGER", "HORSE"]
// ["HORSE", "TIGER", "CAT", "DOG"]
// ["TIGER", "HORSE", "CAT", "DOG"]

您可以通过以下方式轻松完成：

//阵列var fruits=[“香蕉”、“橙色”、“苹果”、“芒果”]；//随机的，随机的fruits.sort（函数（a，b）{return 0.5-Math.random（）}）；//输出console.log（水果）；

请参考JavaScript排序数组

var shuffle = function(array) {
   temp = [];
   originalLength = array.length;
   for (var i = 0; i < originalLength; i++) {
     temp.push(array.splice(Math.floor(Math.random()*array.length),1));
   }
   return temp;
};

Array.prototype.shuffle=function(){
   var len = this.length,temp,i
   while(len){
    i=Math.random()*len-- |0;
    temp=this[len],this[len]=this[i],this[i]=temp;
   }
   return this;
}

// Create a places array which holds the index for each item in the
// passed in array.
// 
// Then return a new array by randomly selecting items from the
// passed in array by referencing the places array item. Removing that
// places item each time though.
function shuffle(array) {
    let places = array.map((item, index) => index);
    return array.map((item, index, array) => {
      const random_index = Math.floor(Math.random() * places.length);
      const places_value = places[random_index];
      places.splice(random_index, 1);
      return array[places_value];
    })
}

可理解的洗牌数组元素的方法设arr1=[“a”，“b”，“c”，“d”]；函数洗牌（数组）{let currentIndex=array.length；while（currentIndex！=0）{let randomIndex=Math.floor（Math.random（）*array.length）；当前索引-=1；let temp=数组[currentIndex]；array[currentIndex]=array[randomIndex]；array[randomIndex]=临时；}返回数组；}设arr2=洗牌（arr1）；arr2.forEach（元素=>console.log（元素））；
