参数1. rnType 表示随机类型
1为输入随机数字
2为随机手机号
3为随机字母
4为随机字母/数字(先字母后数字),一般用于输用户名和密码,所以字母在前
5为随机邮箱
6为随机16进制
7为随机中文(常用中文字库到度娘下载吧)
参数2. rnLen 表示随机的长度
参数3. rnUL 表示字母的大小写。1为大写、2为小写、其他为不区分,默认为不区分
以上三个参数,用不到的参数就不用填,用不到的参数你设置了不会出错,但也不会生效。
比如手机号只要一个rnType参数就行,生成数字就只要rnType、rnLen参数
如果随机结果有字母,且不区分大小写的话,也不用rnUL参数
脚本最后有示例,直接调试下就看出来效果了
---------------------------------------------------------------------
新增加随机函数,生成通过校验的苹果IMEI
可以直接添加到myRand里,比如设成8,需要用的时候直接myRand(8)调用
