title: Auto form filling using java script
body: <p>My requirement is to write one script when I run the script it opens the page and fill the fields and automatically take me to next page.</p>
  
  <p>For e.g. Script for www.irctc.co.in. When we login to irctc it ask the user name and password and when click on submit it redirect to next page.
