javascript - 从数组中获取一个随机数(1 到 6 个数字，如骰子)对象，然后将其从数组中删除

Question

var data = [
    {
        id:1,
        account_name:'Akshay Patil',
        debit:111,
        credit:''
    },
    {
        id:2,
        account_name:'Bharat Chavan',
        debit:222,
        credit:''
    },
    {
        id:3,
        account_name:'Chetan Kore',
        debit:333,
        credit:''
    },
    {
        id:4,
        account_name:'Dilip Patil',
        debit:444,
        credit:''
    },
    {
        id:5,
        account_name:'Eshawr Dange',
        debit:555,
        credit:''
    },
    {
        id:6,
        account_name:'farhan Khan',
        credit:666,
        debit:''
    },
    {
        id:7,
        account_name:'Ganesh Shine',
        credit:777,
        debit:''
    },
    {
        id:8,
        account_name:'Hemant Birje',
        credit:888,
        debit:''
    }
]

当生成随机数后从数组中删除对象时会发生问题，此时随机数大于数组长度，然后出现无法读取属性的错误。

这是我的main.s文件

function(){
 user.wrapper.find('.randomMove').off('click').on('click', function(event){
        var dice = {
           sides: 6,
           roll: function () {
            var randomNumber = Math.floor(Math.random() * this.sides) + 1;
                return randomNumber;
           }
        }
        var result = dice.roll();
        result--;
        //setDataInTable(result);        
        user.data.splice(result,1);
   });
  }

使用这个js我拼接生成的随机对象并设置为表数据

Answer 1

这应该可行

var len = data.length;
var rand = Math.random() * (len - 0) + 0;

var selected = data[rand];
data.splice(rand, 1)
