如何设置或更改最小密码长度

Question

我想设置一个密码并将其限制为“密码必须包含40个十六进制字符”。将只允许使用十六进制字符的替代方法是什么？

道具

autoComplete:"new-password"
label:"Password"
margin:"normal"
maxLength:100
name:"meter_password"
onChange:bound bound _onChange()
pattern:"[A-Fa-f0-9]{40}"
required:true
select:false
style:{…}
tabIndex:107
type:"password"
value:""
