字段验证需要正则表达式帮助
我需要按照以下要求验证该字段：
- 必须至少 6 个字符，
- 不得超过 50 个字符。
- 必须包含至少一个字母字符
- 必须至少有一个“其他”字符。 “其他”字符只能是数字或以下 8 个字符中的任何一个：下划线、连字符、句点、与号、美元、星号、感叹号、@ 符号
我想出了以下正则表达式，但它并不总是有效它允许一些我想排除的特殊字符
/^(?!.*(.)\1)((?=.*[^\w\d\s])(?=.*\w)|(?=.*[\d])(?=.*\w)).{6,50}$/
I need to validate the field with the following requirements:
- must be at least 6 characters
- must be no more than 50 characters.
- must contain at least one alphabetical character
- There must be at least one "Other" character.
An "Other" character can only be either a number or any one of the following 8 characters: underscore, hyphen, period, ampersand, dollar, star, exclamation, the @ symbol
I came up with the following regex but it does not always works it allows some special characters which I want to exclude
/^(?!.*(.)\1)((?=.*[^\w\d\s])(?=.*\w)|(?=.*[\d])(?=.*\w)).{6,50}$/

它真的必须是正则表达式吗？我只会编写一个函数来测试这些标准。
那不是更容易吗？
Does it really have to be a regexp? I would just write a function that tests each of these criteria.
Isn't that easier?
这是因为您在末尾匹配
.，因此如果满足所有条件，则最多 50 个剩余字符可以是任何内容。我会用：It's because you match with
.at the end, so if all your conditions are met, then any leftover characters up to 50 can be anything. I would use:我想说你需要以下内容：（
字母或符号）*
字母+
符号+
（字母或符号）*
OR
（字母或符号）*
符号+

（字母或符号）*
I would say you need the following:
(letters or symbols)*
letters+

OR
