Ajax Overview

Why Ajax? 

  • Asynchronous communication replaces "synchronous request/response model." 
    • A user can continue to use the application while the client program requests information from the server in the background 
    • Separation of displaying from data fetching 
  • "Partial screen update" replaces the "click, wait, and refresh" user interaction model 
    • Only user interface elements that contain new information are updated asynchronously (no interruption to user operation) 
    • The rest of the user interface remains displayed without interruption (no loss of operational context)
