/* 生成指定0~范围指定个数随机数*/function randRangeNumberFromOne(randomBeforeLotteryArr, range, count, except) {    var randomNumberSet = [];    for (var r = 1; r <= range; r++) {        if (r < 10) {            r = "0" + r;        }        randomNumberSet.push(r.toString());    }    /* 胆拖会去掉已经选择的胆码*/    if (except.length > 0) {        except.forEach(function (e) {            randomNumberSet.splice(randomNumberSet.indexOf(e), 1);        });    }    while (randomBeforeLotteryArr.length < count) {        var randomNum = randomNumberSet[parseInt(Math.random() * randomNumberSet.length+1, 10)-1];        randomNumberSet.splice(randomNumberSet.indexOf(randomNum), 1);        randomBeforeLotteryArr.push(randomNum);    }    return randomBeforeLotteryArr;}

usage

for(var i=0;i<=272618;i++){   console.log('随机第'+i+'次');   var arr = randRangeNumberFromOne([],33,6,[]);   console.log(arr);   var count = 0;   /*['03','06','16','23','26','30'].forEach(function(e){        if(arr.indexOf(e)>-1){            count++;        }   })   if(count>=6){      break;   }*/   console.log(randRangeNumberFromOne([],16,1,[]));}
