Match only unicode letters
提问by user1767962
i have the following regex that allows only alphabets :
我有以下只允许字母的正则表达式：
/[a-zA-Z]+/
a = "abcDF"
if (a.match(/[a-zA-Z]+/) == a){
//Match
}else{
//No Match
}
How can I do this using p{L} (universal - any language like german, english etc.. )
我如何使用 p{L}（通用 - 任何语言，如德语、英语等......）
What I tried :
我试过的：
a.match(/[p{l}]+/)
a.match(/[\p{l}]+/)
a.match(/p{l}/)
a.match(/\p{l}/)
but all returned null for the letter a = "aB"
但是对于字母 a = "aB" 都返回 null

Starting with ECMAScript 2018, JavaScript finally supports Unicode property escapesnatively.
从 ECMAScript 2018 开始，JavaScript 终于原生支持Unicode 属性转义。
For older versions, you either need to define all the relevant Unicode ranges yourself. Or you can use Steven Levithan's XRegExppackage with Unicode add-onsand utilize its Unicode property shortcuts:
对于旧版本，您需要自己定义所有相关的 Unicode 范围。或者，您可以将 Steven Levithan 的XRegExp包与 Unicode 附加组件一起使用，并利用其 Unicode 属性快捷方式：
var regex = new XRegExp("^\p{L}*$")
var a = "abc??üéèê"
if (regex.test(a)) {
// Match
} else {
// No Match
}

If you are willing to use Babelto build your javascript then there's a babel-plugin I have released which will transform regular expressions like /^\p{L}+$/or /\p{^White_Space}/into a regular expression that browsers will understand.
如果你愿意使用Babel来构建你的 javascript，那么我发布了一个 babel-plugin，它可以将正则表达式像/^\p{L}+$/或/\p{^White_Space}/转换成浏览器可以理解的正则表达式。
