如何使用JavaScript获取链接的重定向链接？

Question

I want to open the google scholar links in my html . As the Google scholar link is redirecting to the particular site(e.g abc.com). The abc.com is not opening in iframe. iframe display an error for that link: "refused to connect".

<iframe src="
http://scholar.google.se/scholar_url?url=https://www.cabdirect.org/cabdirect/abstract/20193167581&hl=en&sa=X&d=11331141127468683170&scisig=AAGBfm0gdJ83JW1o6Xb82uD9bNnZNNTSeQ&nossl=1&oi=scholaralrt&hist=92LQev8AAAAJ:14285763116787501533:AAGBfm0HS_SbXaAMNGPcdwbkLaUuKU410g"></iframe>

How can i get the actual link abc.com using the Google scholar link:

The Sample Google link is: http://scholar.google.se/scholar_url?url=https://www.cabdirect.org/cabdirect/abstract/20193167581&hl=en&sa=X&d=11331141127468683170&scisig=AAGBfm0gdJ83JW1o6Xb82uD9bNnZNNTSeQ&nossl=1&oi=scholaralrt&hist=92LQev8AAAAJ:14285763116787501533:AAGBfm0HS_SbXaAMNGPcdwbkLaUuKU410g

And it is redirecting to the site: https://www.cabdirect.org/cabdirect/abstract/20193167581

Answer 1

The redirect URL is stored in a GET parameter.

function getRedirectLink(link) {
  var url = new URL(link);
  var redirect = url.searchParams.get("url");
  return redirect
}
