javascript - True Sentence Case（处理常见句子）

Question

真句案例

这不应与“标题案例”相混淆。句格只大写句子的第一个单词；这句话的其他词保持不变。

Stackoverflow 上的各种文章和答案都没有解决下面解释的问题：最相关的（虽然 6 岁）是在 javascript 中将字符串转换为句子大小写，但不起作用。

一个段落（或文章）可能包括几个由句号“.”分隔的句子。

我正在寻找至少应该处理下面描述的情况的“SentenceCase”代码。

目的是仅将第一个单词（如果适用）大写，而不是尝试修改或尝试更正句子文本的其余部分。

该功能应解决以下标准情况：

// ----------------------------------

// Original:  this is a sentence
// Becomes :  This is a sentence

// 2. Two or more sentences:
// -------------------------

// Original:  first sentence. second sentence .   third sentence.
// Becomes :  First sentence. Second sentence .   Third sentence.

// -------------------------------------------------------------

// Original:  kHz is a unit of measure. kPascal too.
// Becomes :  kHz is a unit of measure. kPascal too.

// Original:  iPads are sold by Apple. iTones are too.
// Becomes :  iPads are sold by Apple. iTones are too.

// 5. Sentences starting with a special chars/words:
// -------------------------------------------------

// Original:  https//: is the web address. www.stack.com is another website.
// Becomes :  https//: is the web address. www.stack.com is another website.

// Original:  .Net is a programming language. foo_bar is a variable it uses.

// Original:  concrete5 is an open-source content management system.
// Becomes :  concrete5 is an open-source content management system.

// 6. Text inside quotes:
// ----------------------

// Original:  "we should stay home" said the governor. 'we will' we answered.
// Becomes :  "we should stay home" said the governor. 'we will' we answered.

// Original:  "this ". was text in quotes
// Becomes :  "this ". Was text in quotes

// 7. Sentences with Abbreviations:
// --------------------------------

// Original:  reporting time is 09:00 a.m. and leaving at 05:00 p.m. every day.
// Becomes :  Reporting time is 09:00 a.m. and leaving at 05:00 p.m. every day.

// 8. Short sentences with single words:
