如何验证中文（unicode）和英文名称？

问题描述

我有一个多语言网站（中文和英文）。

I have a multilingual website (Chinese and English).

我想在javascript中验证文本字段（名称字段）。到目前为止，我有以下代码。

I like to validate a text field (name field) in javascript. I have the following code so far.

var chkName = /^[characters]{1,20}$/;

if( chkName.test("[name value goes here]") ){
  alert("validated");
}

问题是，/ ^ [字符] {1,20} $ /只匹配英文字符。是否可以匹配任何（包括unicode）字符？我以前使用以下正则表达式，但我不想在每个characeters之间留出空格。

the problem is, /^[characters]{1,20}$/ only matches English characters. Is it possible to match ANY (including unicode) characters? I used to use the following regex, but I don't want to allow spaces between each characeters.

/^(.+){1,20}$/

推荐答案

你可能会检查并进行一些研究以准确找到您想要允许的字符范围：

You might check out Javascript + Unicode regexes and do some research to find exactly which ranges of characters you want to allow:

请参阅

在阅读了这两个以及一些额外的研究后，您应该能够找到合适的值来完成以下内容： / ^ [ - 'az \ u4e00-\ u9eff] {1,20} $ / i

After reading those two and a little extra research you should be able to find appropriate values to complete something like: /^[-'a-z\u4e00-\u9eff]{1,20}$/i
