匹配符号的正则表达式:!$%^& *()_ + |〜 - =`{} []:" ;;'<>?,. / [英] Regex to Match Symbols: !$%^&*()_+|~-=`{}[]:";'<>?,./
问题描述
我正在尝试在JavaScript中创建一个Regex测试,测试字符串以包含以下任何字符:
I'm trying to create a Regex test in JavaScript that will test a string to contain any of these characters:
!$%^&*()_+|~-=`{}[]:";'<>?,./

这是我正在研究一个非常酷的密码更改应用程序。如果你感兴趣的是这里剩下的代码。
It's for a pretty cool password change application I'm working on. In case you're interested here's the rest of the code.
我有一个列出密码要求的表当最终用户键入新密码时,它将测试一个正则表达式数组并在相应的表行中放置一个复选标记,如果它...检出:)我只需要添加这一个来代替 validation
array。
I have a table that lists password requirements and as end-users types the new password, it will test an array of Regexes and place a checkmark in the corresponding table row if it... checks out :) I just need to add this one in place of the 4th item in the validation
array.
var validate = function(password){
valid = true;
var validation = [
RegExp(/[a-z]/).test(password), RegExp(/[A-Z]/).test(password), RegExp(/\d/).test(password),
RegExp(/\W|_/).test(password), !RegExp(/\s/).test(password), !RegExp("12345678").test(password),
!RegExp($('#txtUsername').val()).test(password), !RegExp("cisco").test(password),
!RegExp(/([a-z]|[0-9])\1\1\1/).test(password), (password.length > 7)
]
$.each(validation, function(i){
if(this)
$('.form table tr').eq(i+1).attr('class', 'check');
else{
$('.form table tr').eq(i+1).attr('class', '');
valid = false
}
});
return(valid);
}
是的,还有相应的服务器端验证!
推荐答案
这个正则表达式非常简单。只需使用一个字符类。连字符是字符类中的特殊字符,因此它必须是第一个:
The regular expression for this is really simple. Just use a character class. The hyphen is a special character in character classes, so it needs to be first:
/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/
您还需要转义其他正则表达式元字符。
You also need to escape the other regular expression metacharacters.
编辑:
连字符是特殊的,因为它可以用来表示一系列字符。这个相同的字符类可以通过以下范围进行简化:
The hyphen is special because it can be used to represent a range of characters. This same character class can be simplified with ranges to this:
/[$-/:-?{-~!"^_`\[\]]/
有三个范围。 '$'到'/',':'到'?','{'到'〜'。最后一个字符串不能用一个范围更简单地表示:!^ _` []。
There are three ranges. '$' to '/', ':' to '?', and '{' to '~'. the last string of characters can't be represented more simply with a range: !"^_`[].
使用ACSII表查找字符类的范围。
Use an ACSII table to find ranges for character classes.
