How to enable ajax request in Rails application

Question

Someone please explain me how do I send ajax request to enable ajax in my application. In my controller I have this code in the respond_to block

 format.html {  }
 format.xml  {  }
 format.js {}

Normally .html response is always sent back to the user. But I want to know how can I enable .xml or .js and how this works.

Check out the Rails Guides on Working with Javascript in Rails . The linked to section should be particularly helpful in understanding this problem.
