Check if a link on the page contains a string

(I'm a complete newbie so please forgive me if this isn't clear!)

Is there a way to check if a URL (on the page, not of the page) contains a certain string, and then open said link? e.g. on a news website, check if a link (article) on the page contains "entertainment" and then open any links that contain that, in order to open all articles related to entertainment.

I've only been able to do it for if the URL of the page I'm on contains xyz, using window.location.href.indexOf, and not for URLs that are on the page.

ES6 Style

for (let link of document.getElementsByTagName("a")) {
  if (link.href.search("stack") > -1)  link.click();
}

Here's an example of doing what you need. I've added 3 links in HTML and added some Javascript to find the one with the text stack in it and click it.

var links = document.getElementsByTagName("a");

for (var i = 0, l = links.length; i < l; i++) {
  var link = links[i];
  if (link.href.indexOf("stack") !== -1) {
    link.click();
  }
}
