前言
本文主要给大家介绍了关于利用javascript随机生成一定位数密码的相关内容，分享出来供大家参考学习，下面话不多少，来一起看看详细的介绍吧。
需求
随机生成一定位数的密码，有最小个数和最大个数，必须包含数字、大小写字母，和特殊字符比如（- _ #）；

代码
function createPassword(min,max) {
//可以生成随机密码的相关数组
var num = ["0","1","2","3","4","5","6","7","8","9"];
var english = ["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"];
var ENGLISH = ["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"];
var special = ["-","_","#"];
var config = num.concat(english).concat(ENGLISH).concat(special);
//先放入一个必须存在的
var arr = [];
arr.push(getOne(num));
arr.push(getOne(english));
arr.push(getOne(ENGLISH));
arr.push(getOne(special));
//获取需要生成的长度
var len = min + Math.floor(Math.random()*(max-min+1));
for(var i=4; i使用
传入一个生成的密码的最小位数，和最大位数，即可返回一个随机密码
console.log(createPassword(8,15));
