How to Redirect each link on the webpage through another link using JavaScript or any html? I have a website - www.example.com I have few links on each page like - www.link1.com

Solution 1:

var remember = [].slice;
var to = 'a';
var post = document.getElementsByTagName(to);
var relevant = remember.call(post);
var code = 'https://example.com?redirect=';

relevant.forEach(function(atag) {
  var href = atag.href;

  if ( href ) {
    atag.href = code + encodeURIComponent(href);
  }
});
