I am loading some content inside an iframe. I want this content to behave as-if it was inside a <pre> tag - namely for it to respect line breaks. I am using javascript to set the style of the body element of this iframe.
I am wondering if it would be possible to set a particular style that will cause the body of this iframe to act like it's inside <pre/>.

您可以在 http://www.w3.org/TR/CSS2/sample.html" rel="noreferrer">http://www. w3.org/TR/CSS2/sample.html 只需将相同的样式应用于您想要充当前置元素的元素，瞧，您就完成了
。这基本上是
you can find the default setting or how they're suppose to be at http://www.w3.org/TR/CSS2/sample.html just apply the same style to the element you want to behave as a pre element and voila you're done

如果您只对保留换行符而不是空格感兴趣，那么我建议使用：
这会将多个连续的空格字符折叠为一个但保留换行符。缺点是它仅在 IE 8 及更高版本中受支持。
If you're only interested in preserving line breaks but not whitespace then I suggest using:
This will collapse multiple consecutive white space characters into one but preserve line breaks. The downside is that it's only supported in IE versions 8 and up.
尝试将元素的
white-space样式设置为pre值。Try setting the element's
white-spacestyle to a value ofpre.如果您只想让它在像
pre这样的换行符上起作用，请使用 css:white-space: preIf you just want it to act on linebreaks like
pre, use the css:white-space: pre
