jQuery Validate 插件 - 密码检查 - 最低要求 - 正则表达式 [英] jQuery Validate plugin - password check - minimum requirements - Regex

问题描述

我的密码检查器有点问题.

I've got a little problem with my password-checker.

有一个包含一些字段的注册表单.我使用 jQuery Validate 插件来验证用户输入.

There's got a registration form with some fields. I use jQuery Validate plugin to validate user-inputs.

除了密码验证之外，一切正常:

It all works except the password-validation:

密码应满足一些最低要求:

The password should meet some minimum requirements:

• 最小长度:8 -> 我只使用 'minlength: 8'
• 至少一个小写字符
• 至少一位数字
• 允许的字符:A-Z a-z 0-9 @ * _ - .！

目前我使用此代码验证密码:

At the moment I use this code to validate the password:

$.validator.addMethod("pwcheck",
function(value, element) {
   return /^[A-Za-z0-9d=!-@._*]+$/.test(value);
});

本准则适用于允许的字符，但不适用于最低要求.我知道您可以将例如 (?=.*[a-z]) 用于小写要求.但我就是不让它工作.

This Code works for the allowed characters but not for minimum requirements. I know that you can use for example (?=.*[a-z]) for a lower-case-requirement. But I just don't get it to work.

如果我添加 (?=.*[a-z]) 整个代码将不再起作用.我需要知道如何正确地将代码添加到现有代码中.

If I add (?=.*[a-z]) the whole code doesn't work anymore. I need to know how to properly add the code to the existing one.

感谢您的回答！

推荐答案

如果我添加 (?=.*[a-z]) 整个代码将不再起作用.

If I add (?=.*[a-z]) the whole code doesn't work anymore.

在此处添加:

/^(?=.*[a-z])[A-Za-z0-9d=!-@._*]+$/

但是，如果没有前瞻，这样做会容易得多:

However, it's much easier to do this without a lookahead:

$.validator.addMethod("pwcheck", function(value) {
   return /^[A-Za-z0-9d=!-@._*]*$/.test(value) // consists of only these
       && /[a-z]/.test(value) // has a lowercase letter
       && /d/.test(value) // has a digit
});
