随机生成54张扑克牌

let pai = [];
        for(let i=0;i<54;i++){
            let a;
            do{
                a = parseInt(Math.random()*54);
            }while(pai.indexOf(a)>-1);
             pai.push(a);
        }
        let result = [];
        let paimina = ["黑桃","梅花","红桃","方块"];
        let haoma = ["A","2",3,4,5,6,7,8,9,10,"J","Q","K"];
        pai.forEach(item=>{
            if(item == 53){result.push("大王")
            }else if(item == 52) {result.push("小王");
            }else{
                result.push(paimina[parseInt(item/13)] + " - " + haoma[parseInt(item%13)])
            }
        })
        console.log(result);
