body: <p>How to use jQuery to make Ajax request in Grails pages?</p>
  
  <p>How to setup a URL hitting a method on Grails Controller? Let's say controller:'airport', action:'getJson' and input to the action is 'iata'.</p>
  
  <p>I am able to set static url as <code>http://localhost:8080/trip/airport/getJson</code> but not able to figure out how to pass input for iata specifically.</p>
  
  <p>I am fairly new to Grails and following IBM's 'Mastering the Grails' tutorial series. Do suggest me some good tutorial on using jQuery with Grails.</p>
