js 生成概率相同的1-4 随机数

var random1=0;

var random2=0;

var random3=0;

var random4=0;

var count=10000000;

var randomNum;

var myDate = new Date();

myDate.getTime();

for(var i=0;i<count;i++){

randomNum = Math.round((Math.random()*myDate.getTime())%1000000000000)%5

if(randomNum==1){

random1++;

}else if(randomNum==2){

random2++;

}else if(randomNum==3){

random3++;

}else if(randomNum==4)

random4++;

}

alert("1出现的概率是："+Math.round((random1/count)*100)+"<br/> 2出现的概率是："+Math.round((random2/count)*100)+" 3出现的概率是："+Math.round((random3/count)*100)+" 4出现的概率是："+Math.round((random4/count)*100));
