今天做阿里前端笔试,做到了随机数,是一道挺基础的题,但平时很少接触到这个,考试时间紧迫,自己基础也不牢固,没好好写出来,现在有重新码一遍,也加深自己的印象,作为第一篇在博客园安家落户的随笔
<!doctype html><html lang="zh-cn"><head><meta charset="UTF-8"><title>随机数</title><script type="text/javascript">function GetRandomNum(Min,Max){var Range=Max-Min;var Rand=Math.random();return(Min+Math.round(Rand*Range));}var num=GetRandomNum(1,10);//document.write(num);alert(num);var chars = ['0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];function generateMixed(n) {var res = "";for(var i = 0; i < n ; i ++) {var id = Math.ceil(Math.random()*35);res += chars[id];}return res;}</script></head><body></body></html>
