How to make scripts work on newly created elements

Many scripts are created to work on the page on loading only. Is there a simple way to make them work dynamically.

Here are examples of scripts in here..

@wOxxOm No luck.. Could you please show me how would it work with @ahuanguchi highlight-external-links

// ==UserScript==
// @name         highlight-external-links
// @namespace    https://github.com/ahuanguchi
// @version      1.0.2
// @description  Highlight all external links in lime green.
// @author       ahuanguchi
// @match        *://*/*
// @grant        none
// @run-at       document-start
// ==/UserScript==

window.addEventListener("load", function () {
  function splitHref(givenHref) {
    return givenHref.replace(/^https?:\/\//, "").split("/");
  }
  var i, currentA, currentHref, anchorParts, locationParts;
  var anchors = document.getElementsByTagName("a");
  var numAnchors = anchors.length;
  for (i = 0; i < numAnchors; i += 1) {
    currentA = anchors[i];
    currentHref = currentA.href;
    anchorParts = splitHref(currentHref);
    locationParts = splitHref(window.location.href);
    if (currentHref.slice(0, 4) === "http" && anchorParts[0] !== locationParts[0]) {
      currentA.style.backgroundColor = "#bfff00";
    }
  }
});

Well, luck has nothing to do with it.

@wOxxOm on some websites like Tumblr dashboard, it would cover elements that are not needed. See the following screenshots..

What do you think is the proper way to select and exclude these elements? or perhaps have them selected with a proper style?

Well, technically speaking those are external links.

To exclude by CSS selector edit the setMutationHandler's parameter: a[href*="//"]:not(.some-class) or even a[href*="//"]:not(.some-class):not(#some-id):not(sometag)

P.S. instead of http the script now looks for // because many web pages don't specify the protocol.

Great! I just had to add && n.textContent !== '' to exlude non texted elements. Thank you, specially for the awesome setMutationHandler function.
