正则验证问题，6-16位字母或数字


回复讨论(解决方案)

只能是 字母+数字 还是 字母 还是 数字 ?

/[0-9]/                   //数字
/[a-zA-Z]/              //字母
/[a-z0-9]/              //数字+字母

/[a-z0-9]{6,16}/ 

允许纯字母或数字串
/^[a-z0-9]{6,16}$/

必须同时含有字母和数字
/^(?=.{6,16})(?=.*[a-z])(?=.*[0-9])[0-9a-z]*$/

只能是 字母+数字 还是 字母 还是 数字 ?


字母加数字

/^[a-z0-9]{6,16}$/i
