今天迎来了2018年第一场雪,这个美好的日子,总的写点什么纪念一下,在这里写了一个在js中使用Math.random()函数,随机生成四位数的验证码及其验证码换颜色. js代码如下: var arrayTest= ["m","n","v","x","z","a","b","c","d","e","f…
<script> // 封装一个随机生成数字的函数 function random(a, b) { var n = Math.round(Math.random() * (a - b) + b); return n; } //=====================================有漏洞版============================================= function getCode(){ //定义一个字符串把所有可能都装进去,全部字母以及数字…
