[英]Validating UTF-8 names in JavaScript (Node.js) with XRegExp
I'm trying to check if a given UTF-8 string consists of letters only. 我正在尝试检查给定的UTF-8字符串是否仅包含字母。
I tried the solution I found here: Validating user's UTF-8 name in Javascript 我尝试了在这里找到的解决方案: 在Javascript中验证用户的UTF-8名称
Given string: Ciesiołkiewicz
给定字符串:
Ciesiołkiewicz
is tested with var XRegExp = require('xregexp').XRegExp('^\\\\p{L}+$');
用
var XRegExp = require('xregexp').XRegExp('^\\\\p{L}+$');
And it's not working because of "ł" letter 而且由于“ł”字母而无法正常工作
I tried XRegExp('^[\\\\p{Latin}\\\\p{Common}]+$');
我尝试了
XRegExp('^[\\\\p{Latin}\\\\p{Common}]+$');
but it's too much, it accepts polish letters but also characters like "$" etc 但是它太多了,它接受波兰字母,但也可以接受“ $”等字符
How can I validate it against letters only? 如何仅针对字母验证它? I don't want to type them into regexp manually.
我不想手动将它们输入到regexp中。
var XRegExp = require('xregexp').XRegExp;
var re = new XRegExp('^\\p{L}+$');
console.log(re.test('Ciesiołkiewicz'));
console.log(re.test('1Ciesiołkiewicz2'));
console.log(re.test('привет'));
console.log(re.test('пр1вет'));
> true
> false
> true
> false
works perfectly. 完美地工作。
how about a character range like [aZ]? 像[aZ]这样的字符范围如何? thats what i usually use if im looking only for letters
如果我只寻找字母,多数民众赞成在我通常使用的
