Website Scripting

Scrolls 500 pixels down after 1 second (1000 ms), so the page has loaded. Try other numbers to find the right spot; the delay may not be needed on every site.

setTimeout(window.scrollTo.bind(null, 0, 500), 1000);

Scrolls from top to bottom at a set speed. Copy it and change SPEED (1 to 1000) and JUMP_TO_TOP (back to the top at the end: true or false).

var SPEED = 20; //change the speed for faster/slower scrolling. Value between 1 and 1000
var JUMP_TO_TOP = true; //Scrolls back to top when scrolling reaches bottom. either true or false

var fps = 100;
var speedFactor = 0.001;
var minDelta = 0.5;
var autoScrollSpeed = 10;
var autoScrollTimer, restartTimer;
var isScrolling = false;
var prevPos = 0, currentPos = 0;
var currentTime, prevTime, timeDiff;

window.addEventListener("wheel", handleManualScroll);
window.addEventListener("touchmove", handleManualScroll);

function handleManualScroll(){
  currentPos = window.scrollY;
  clearInterval(autoScrollTimer);
  if (restartTimer){
    clearTimeout(restartTimer);
  }
  restartTimer = setTimeout(function(){
    prevTime = null;
    setAutoScroll();
  }, 50);
}

window.addEventListener("scroll", function (e) {
  currentPos = window.scrollY;
  if((window.innerHeight + window.pageYOffset) >= document.body.offsetHeight){
    //scrolling reached bottom.
    if(JUMP_TO_TOP){
      window.scrollTo(0, 0)
      currentPos = 0;
    }
    else{
      clearInterval(autoScrollTimer);
    }
  }
});

function setAutoScroll(newValue){
  if(newValue){
    autoScrollSpeed = speedFactor * newValue;
  }
  if(autoScrollTimer){
    clearInterval(autoScrollTimer);
  }
  autoScrollTimer = setInterval(function(){
    currentTime = Date.now();
    if(prevTime){
      if(!isScrolling){
        timeDiff = currentTime - prevTime;
        currentPos += autoScrollSpeed * timeDiff;
        if(Math.abs(currentPos - prevPos) >= minDelta){
          isScrolling = true;
          window.scrollTo(0, currentPos);
          isScrolling = false;
          prevPos = currentPos;
          prevTime = currentTime;
        }
      }
    }
    else {
      prevTime = currentTime;
    }
  }, 1000 / fps);
}

setAutoScroll(SPEED);

Reloads the page every 60 seconds. Each reload runs the script again, so it keeps going.

setTimeout(function(){
  window.location.reload(true);
}, 60000);

Waits 1 second, then plays the first video on the page.

setTimeout(function(){document.getElementsByTagName('video')[0].play()}, 1000);

Some sites show their mobile version on Android players. This makes the page think it’s a Full HD browser.

const viewportWidth = 1920;
const viewportHeight = 1080;
const devicePixelRatio = 2;

// Set the viewport meta tag to control the layout on mobile devices
const viewportMetaTag = document.querySelector('meta[name=viewport]');
if (viewportMetaTag) {
viewportMetaTag.content = `width=${viewportWidth}, height=${viewportHeight}, initial-scale=${1 / devicePixelRatio}, maximum-scale=${1 / devicePixelRatio}, user-scalable=0`;
}

// Set the window size to match the viewport
window.resizeTo(viewportWidth, viewportHeight);

// Trigger a resize event to ensure proper rendering
const resizeEvent = new Event('resize');
window.dispatchEvent(resizeEvent);

Replace the user name and password. Works for Microsoft, Office 365, Hotmail and Power BI sites.

var user = "YOUR_USERNAME_HERE";
var pass = "YOUR_PASSWORD";
function setValue(id, value){
  document.getElementById(id).value = value;
  document.getElementById(id).dispatchEvent(new Event("change"));
}
function clickButton(id){
  document.getElementById(id).click();
}
setTimeout(setValue.bind(null, 'i0116', user), 1000);
setTimeout(clickButton.bind(null, 'idSIButton9'), 1100);
setTimeout(setValue.bind(null, 'i0118', pass), 1800);
setTimeout(clickButton.bind(null, 'idSIButton9'), 2000);

When it comes to logging into a website, there is no one-size-fits-all solution. Each website is a different system and needs a tailored approach. While JavaScript programming skills would be beneficial, it is certainly possible to create the script without any technical background. We gladly assist our subscription customers with simple scripts.

The login script performs the following actions:

1. Find the username input field and fill it with our username
2. Find the password input field and fill it with the password
3. Find the login button and click it

First, we need to teach the script to find the elements in the web page. To do so, we need to find out what the IDs of the elements are. This is possible in every browser, but we focus on Chrome in this guide. Navigate to the page where you want to automate the login and open the developer tools. (Settings -> More Tools -> Developer Tools)

In the developer tools, choose the Elements tab if not already selected. Then click on the Select Element button (step 1) and mouse over the username input field and click on it (step 2). The HTML code that represents the username field will be highlighted; it should be an <input> tag. Most website creators assign a unique ID to that field that we can use to reference it in the script, in this example it is “user_login” (step 3).

Repeat the same process for the password field. In our example, the password field id is “user_pass“. Ideally, the login button also has an ID attribute (here “login_btn”), in which case we have all the information needed to create the script:

document.getElementById('user_login').value = "YOUR_USERNAME_HERE";

document.getElementById('user_pass').value = "YOUR_PASSWORD_HERE";

document.getElementById('login_btn').click();

Sometimes, however, the login button may not have an ID assigned, but instead, all fields are wrapped in a <form> element. Instead of clicking on the button, we can also call the submit() function on the form itself:

document.getElementById('loginform').submit();

It is possible, however, that the form does not have an ID attribute either. Then we can search for all <form> elements on the page and submit the first one we find, but beware that this only works if there is only one <form> on the page:

document.getElementsByTagName('form')[0].submit();

If you are very unlucky and none of the elements have an ID attribute assigned, then there are 2 options:

1. Contact the website developers and ask them to assign ID values to login page elements
2. Hire a developer to write the script – it’s still possible to find the elements, but it’s beyond the scope of this article. A qualified JavaScript developer should be able to develop the script in about 30 minutes to 1 hour
