推荐答案

根据W3C

According to W3C Textarea api value, it seems that when invoking the .value attribute of textarea, any carriage return or line feed is transformed into a LINE FEED (10) character (in fact W3C says CRFL but it seems the browsers prefer only LF) - so a script can be platform-independent on line feeds.

在表单数据中，精细的提要似乎转换为 CRLF (13 + 10).

In a form data, it seems that the fine feeds are transformed into CRLF (13+10).

W3C还谈到了原始值，但它可能是任何javascript引擎的内部功能，并且似乎在Javascript中不可用.

W3C speaks also about a raw value but it's probably internal to any javascript engine and it seems it's not available in Javascript.
