HTML not reading %0A
提问by Amadan
I have this code:
我有这个代码：
elf='%0A';
document.getElementById('writebox').innerHTML=("hello there"+elf+"friend");
When the function that this is inside is called, the text that appears in the div is not a line break, but rather just "%0a". This confuses me, because inside another different function, elf works fine. Any ideas why?
当调用 this 内部的函数时，出现在 div 中的文本不是换行符，而只是“%0a”。这让我很困惑，因为在另一个不同的函数中，elf 工作正常。任何想法为什么？

Different encoding. %0Ais URL-encoding of a newline, which you would use in (obviously) URLs. &x0a;would be the HTML-encoding of the same character that you would use in HTML, but it doesn't work, for a variety of reasons. To break a line in HTML, you can use <br>tag.
不同的编码。%0A是换行符的 URL 编码，您将在（显然）URL 中使用它。&x0a;将是您将在 HTML 中使用的相同字符的 HTML 编码，但由于各种原因，它不起作用。要在 HTML 中换行，您可以使用<br>tag。
EDIT:
编辑：
the problem wit a
<br />tag is that all i want is simply a new line.<br />creates WAY too much white space
<br />标签的问题是我想要的只是一个新行。<br />创造了太多的空白
No, it doesn't:
不，它不会：
foo<br>
bar
