随机生成不重复的数组

function random(arr) {
        var newArr = [];
        var temp = {};
        function randomNumber() {
            for (var i = 0; i < arr.length; i++) {
              var ArrIndex = Math.floor(Math.random()*arr.length);
              if(!temp[arr[ArrIndex]]) {
                  newArr.push(arr[ArrIndex])
                  temp[arr[ArrIndex]]=1;
              }
            }
            
        }
        randomNumber();
        return newArr
    }
    var a = random(["2", "34", "14", "98", "21", "22", "32", "134"])

    for(var j= 0;j<2;j++) {
        $("#container").append("<div>"+ a[j] +"</div>")
    }
