有没有办法让媒体打印CSS的正常观点？ [英] Is there a way to enable media print css to a normal view?

问题描述

我开发了一个包含大量打印媒体查询的网站，以在打印页面时调整内容。当您转到Web浏览器的打印模式时，查询效果很好。但我想在常规网页上应用/删除 @media print 查询，而无需进入打印模式（通过单击按钮）是否有任何方法可以实现这个？

I developed a website with a bunch of print media queries to align stuff when printing the page. when you go to the print mode on web browser, the queries works great. but i want apply/remove those @media print queries on a regular web page without having to go into the printing mode.(by clicking a button) is there any way to achieve this?

推荐答案

添加到yezzz的答案：如果您的HTML中链接了打印CSS，如

To add to yezzz's answer: If you have the print CSS linked in the HTML like

<link rel="stylesheet" media="print" href="...">

您可以移除媒体属性以启用无论是在服务器上还是使用Javascript：

you can remove the media attribute to enable those styles everywhere, either on the server or with Javascript:

document.querySelector('[media="print"]').removeAttribute('media');

请注意，如果打印样式表中的语句被封装在 @media print {} 规则。

Note, that this doesn't work, if the statements in the print stylesheet are wrapped in a @media print {} rule.
