如何为HTML标签属性使用多行值? (即如何逃脱换行符?) [英] How can I use a multiline value for an HTML tag attribute? (i.e. how do I escape newline?)
问题描述
如何在HTML标签属性中包含换行符?
How do I include a newline in an HTML tag attribute?
例如:
<a href="somepage.html" onclick="javascript: foo('This is a multiline string.
This is the part after the newline.')">some link</a>
编辑:很抱歉，不好的例子，如果代码恰巧不在javascript中，该怎么办，说:
Edit: Sorry, bad example, what if the tag happened to not be in javascript, say:
<sometag someattr="This is a multiline string.
This is the part after the newline." />
编辑2 :原来字符串中的换行符不是我的问题，这是我正在调用的javascript函数. FWIW，" "可用于HTML属性中的换行符.
Edit 2: Turns out the newline in the string wasn't my problem, it was the javascript function I was calling. FWIW, " " can be used for newline in an HTML attribute.
推荐答案
根据我对HTML标准的记忆，字符实体在属性中起作用，因此可能可以起作用:
From what I remember about the HTML standard, character entities work in attributes, so this might work:
<sometag someattr="This is a multiline string. This is the part after the newline." />
我不确定您想要的换行符"是否应为 (\ n)或 (\ r \ n)，我不确定浏览器是否会按照您想要的方式解释它.
I'm not sure if the "newline" you want ought to be (\n) or (\r\n), and I'm not sure if browsers will interpret it the way you want.
您为什么需要它?您想通过在HTML标签属性中添加换行符来解决什么具体问题?
Why do you need it? What specific problem are you trying to solve by adding a newline in an HTML tag attribute?
