Is there a possibility to get "Chapter 1\nA Title"?Thanks 解决方案 Use getComputedStyle():$('h1').each(function(){ console.log(window.getComputedStyle(this,':before').content);});before() is a jQuery method used to traverse the DOM, it gets/sets the preceding element, it does not access the pseudo-element.Working JS Fiddle, supplied by Eric.Though there is the unfortunate caveat that this approach returns the literal string used in the content declaration, rather than the actual generated-content. 这篇关于使用jQuery获取CSS的before-content的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
