Tampermonkey autologin : getElementById

Posted under » JavaScript on 5 December 2010

One of the easiest method to practice Javascript is to write a tampermonkey or greasemonkey script.

A simple autologin script for tampermonkey

// ==UserScript==
// @name         temperature update
// @namespace    loop
// @version      0.1
// @description  tired of login
// @author       Hanafi
// @include      http://www.drupalsite.com/
// ==/UserScript==
(function() {
    'use strict';
var name = "admin"
var pass = "bassword"
document.getElementById('edit-name').value = name
document.getElementById('edit-pass').value = pass
You will notice the use strict thingie. It is there for a reason. Use it and don't get put off by it.

However, not all forms has id but have name only. In this case.

var zTextFields = document.getElementsByTagName("input");
for (var i=0; i < zTextFields.length; i++) {
  var thefield;
  if (!thefield) thefield=zTextFields[i].id;
  // Set up your auto-fill values here
  if (thefield == "username") zTextFields[i].value="bradpitt";
  if (thefield == "password") zTextFields[i].value="jolie";
//   alert("field:" + thefield + " value: " + zTextFields[i].value);
