Override Javascript file in chrome

Question

I would like to override a javascript file with my own version of the similar javascript file in chrome.

Let me explain:

1) Lets say a site \'http://example.

Answer 1

you can load your file into the page by adding (or executing in the console) this script.

window.onload = function () {
  var script = document.createElement('script');
  script.src = '//localhost/your/script';
  script.onload = function() {
    console.log('your script have been loaded');
  }
  document.body.appendChild(script);
}

If the file that you want to override contains global functions/variables will be override with the new version in your file or if the elements that you want to override are namespaced just follow the path (e.g My.namespace.method = myNewMethod)
