JS代码：
function s20(){
var data=["0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f"];
for(var j=0;j<500;j++){ //500为想要产生的行数
var result="";
for(var i=0;i<20;i++){ //产生20位就使i<20
r=Math.floor(Math.random()*16); //16为数组里面数据的数量，目的是以此当下标取数组data里的值！
result+=data[r]; //输出20次随机数的同时，让rrr加20次，就是20位的随机字符串了。
}
document.write(result);
document.write("<br/>");
} }
