title: Update html page every X seconds using ajax
body: <p>I saw this post about this issue:
  <a href="https://stackoverflow.com/questions/18320234/auto-refresh-a-html-table-every-x-seconds">Auto Refresh a Html table every x seconds</a></p>
  
  <p>Now, i am using rails, and i would like to do the same thing, but i want to tell rails that i want a remote page, i dont want it to load the full page.
  All i want is pretty much to simulate :remote => true action with ajax.
  I've tried it with regular ajax, and rails loads the whole page instead of just the relevant content that i want.</p>
  
  <p>How can i do it ?</p>
