HTML TextArea 中的换行符

Question

参考以下问题下的可用答案 - What character represents a new line in a text area

textarea 中的换行符应该是 CRLF，尽管在带有换行符的 textarea 中输入数据只会生成 \n，如下面的代码片段所示 -

<textarea id="one" onchange="document.getElementById('contentdiv').innerText=JSON.stringify(document.getElementById('one').value)"></textarea>
<button onclick="document.getElementById('contentdiv').innerText=JSON.stringify(document.getElementById('one').value)">Read Content</button>
<div id="contentdiv"></div>

关于此处看到的更改行为，文本区域的定义标准中是否有 references/changes？

Answer 1

您提供的 link 实际上有答案。

The textarea element value exists in three variants:

the raw value as entered by the user, unnormalized; it may contain CR, LF, or CR LF pair;

the internal value, called “API value”, where line breaks are normalized to LF (only);

the submission value, where line breaks are normalized to CR LF pairs, as per Internet conventions.
