在 javascript 中将连字符的名称大写 [英] Capitalize hyphenated names in javascript

问题描述

我需要将 javascript 中的名称大写，到目前为止我已经在 SO 上找到了这些方法:

I need to capitalize names in javascript and so far I've found these methods on SO:

// doesn't capitalize first letter after hyphen -> gives Bjørn-martin
str.replace(/\w\S*/g, function (txt) { return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase(); });

// capitalizes after hyphen, but also after funny Norwegian characters (æøå) -> gives BjøRn-Martin
str.replace(/\b[\w']+\b/g, function (txt) { return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase(); });

// same as first
str = str.toLowerCase().replace(/^[\u00C0-\u1FFF\u2C00-\uD7FF\w]|\s[\u00C0-\u1FFF\u2C00-\uD7FF\w]/g, function(letter) {
    return letter.toUpperCase();
});

当尝试将 bjørn-martin 大写时，它们都不能同时处理有趣的挪威字符和连字符.

When trying to capitalize bjørn-martin none of them handles both funny Norwegian characters and hyphen.

我不太精通正则表达式，想知道是否有人能指出我正确的方向，以便 bjørn-martin 正确地大写为 Bjørn-Martin.

I'm not exactly well versed in regex and was wondering if anyone could point me in the right direction so that bjørn-martin is correctly capitalized to Bjørn-Martin.

推荐答案

这应该适合您的需求:

var capitalized = input.replace(/(^|[\s-])\S/g, function (match) {
    return match.toUpperCase();
});
