jQuery validate插件:仅接受德语字母 [英] jQuery validate plugin: accept only German letters

问题描述

我正在寻找一种用于jquery validate插件的方法( http://bassistance .de/jquery-plugins/jquery-plugin-validation/)，仅接受字母，包括德语中所谓的Umlaute(öäüÖÄÜß).我对正则表达式不好，所以我写自己的规则失败了. 你有什么主意吗?任何帮助表示赞赏！提前谢谢！ :)

I am looking for a method for the jquery validate plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/), that only accepts letters, including the German so called Umlaute (öäüÖÄÜß).. I googled a bit, but unfortunately couldn't find anything. I'm not good with regex, so I failed writing my own rule.. Do you have any idea? Any help is appreciated! Thx in advance! :)

到目前为止，这是我的方法:

Here is my method so far:

jQuery.validator.addMethod("lettersonly", function(value, element) {
      return this.optional(element) || /^[a-zA-ZüöäÜÖÄß]+$/i.test(value);
    }, "Letters only please"); 

解决方案:该方法有效！问题在于，将元标记"content-type"设置为ISO错误，但是当然必须为UTF-8. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

SOLUTION: The method works! The problem was that the meta tag "content-type" was set wrong to ISO, but it has to be UTF-8 of course. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

推荐答案

[a-zA-Z\u0196\u0228\u0214\u0246\u0220\u0252\u0223]

这些是德语字母(包括普通字母)的unicode字符.

These are the unicode characters for german letters, including the normal letters.

这是正常现象:

[a-zA-ZüöäÜÖÄß]

这取决于您输入的内容.

It depends on what your input is.

以上匹配单个字母.由于您没有提供示例输入，因此我们无法使正则表达式规则更加具体！

The above matches single letters. Since you provide no sample input we can't make the regex rule more specific!
