html密码正则表达式验证 [英] html password regular expression validation

问题描述

• 至少1个大写字母


• 至少1个小写


• 至少1个数字


• 至少1个符号，符号允许 - >！@＃$％^& * _ = + -


• 最少8个字符和最多12个字符

这是我迄今为止。

 < form> 
 Password< input type =textpattern =/ ^ [a-zA-Z0-9！@＃\ $％\ ^ \& * _ = +  - ] {8,12 } $ / g/> 
< input type =submitvalue =Submit/> 
< / form> 
  

JSFiddle

解决方案

试试这种模式

  ^（？=。* [AZ]）（？=。* [AZ]）（？=。* [0-9]）（？=。* [！@＃$ ％^& * _ = +  - ]）。{8,12} 
  

演示

I need to validate password with these requirements:-

• At least 1 Uppercase
• At least 1 Lowercase
• At least 1 Number
• At least 1 Symbol, symbol allowed --> !@#$%^&*_=+-
• Min 8 chars and Max 12 chars

And got stucked a bit, here's what I have so far.

<form>
Password <input type="text" pattern="/^[a-zA-Z0-9!@#\$%\^\&*_=+-]{8,12}$/g" />
<input type="submit" value="Submit" />
</form>

JSFiddle

解决方案

try this pattern

^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#$%^&*_=+-]).{8,12}$
