Bookmarklet to open a webpage and login

Question

I am trying to create a bookmarklet to open a web page, populate credentials, and click login in one shot. Here is the needed bookmarklets:

For opening a webpage:

javascript:location.href='http://www.unt.edu'

For Credentials & login:

javascript:(function(){var d=document;s=d.querySelector;s.call(d,'input[name*=email]').value='[email protected]'; s.call(d,'input[name*=pass]').value='SECRETPASSWORDHERE';s.call(d,'button[id*=login],input[type=button][id*=login],.btn-login').click(); }())

Is it possible to combine both of them considering the asynchronous behavior of opening the web page?

Answer 1

You can combine this in one bookmarklet, but you'll have to click it twice. The first click will open a website, and the next one will do the login.

javascript: (() => {
  const url = 'https://stackoverflow.com/users/login';

  if (location.href !== url) return (location.href = url);

  document.querySelector('input#email').value = 'EMAIL';
  document.querySelector('input#password').value = 'PASSWORD';
  document.querySelector('button#submit-button').click();
})();
