从嵌入代码中提取 facebook url

Question

我需要正则表达式来匹配下面的代码并提取 facebook url。即 - https://www.facebook.com/somevide/videos/778978567/

    <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-video" data-href="https://www.facebook.com/somevide/videos/778978567/" data-width="640" data-show-text="false"><div class="fb-xfbml-parse-ignore"></div></div>

Answer 1

正则表达式所有代码和视频url

(<div id="fb-root[\s\S.]*?data-href="([^"]+).*fb-xfbml-parse-ignore"><\/div><\/div>)

正则表达式视频url

data-href="([^"]+)

使用 javascript dom

var videoUrl = document.getElementsByClassName('fb-video')[0].getAttribute('data-href');
console.log(videoUrl);
