方法一：
var arr = [1,2,3,4,5,6,7,8,9,10];
function randSort1(arr){
for(var i = 0,len = arr.length;i < len; i++ ){ var rand = parseInt(Math.random()*len);
var temp = arr[rand];
arr[rand] = arr[i];
arr[i] = temp;
}
return arr;}
console.log(randSort1(arr));
方法二：
var arr = [1,2,3,4,5,6,7,8,9,10];
function randSort2(arr){ var mixedArray = []; while(arr.length > 0){ var randomIndex = parseInt(Math.random()*arr.length); mixedArray.push(arr[randomIndex]);
arr.splice(randomIndex, 1);
}
return mixedArray;
}
console.log(randSort2(arr));
方法三：
var arr = [1,2,3,4,5,6,7,8,9,10];
arr.sort(function(){
return Math.random() - 0.5;
}) console.log(arr);
