用JavaScript生成由字母数字组成的随机数
Math.random()
,一个广泛使用的JavaScript随机数生成函数,使用它可以生成0-1之间的浮点数,也就是0.XXXXXX这种形式的随机数值,不会生成单位1整数。通过配合toString()
函数可以进一步转换为Base36数值,字符范围扩展为0-9数字+小写26个字母。最后再用substr()
函数提取部分字符就可以得到一个字母数字简单随机数。
如下面JavaScript代码可以随机生成一个8位数密码,效果点此预览。
Math.random().toString(36).substr(2,8)
提示:由于Math.random()
只能生成简单随机数,因此并不适合要求高安全性的使用场景。如果有这方面需求,请用Crypto.getRandomValues()这个API,它可以生成足够强度的安全随机数。比较不好的一点是老旧浏览器不支持,IE要求11及以上版本。
