All Implemented Interfaces:

Direct Known Subclasses:

public abstract class AbstractJcmsAjaxContext
extends Object
implements Serializable

Convenient abstract class to easily develops AJAX handlers in JCMS.

This class tracks variables and various request information available during the initial request of user (as opposed to other AJAX request in which the information is either not available or not the same).

To develop your AJAX handler :

1. Create your own AJAX java class by extending this class.

 package custom;

 public class MyAjaxClass extends com.jalios.jcms.AbstractJcmsAjaxContext {
   public String saySomething(String str)  {
     if (isLogged) {
       return str + " " + loggedMember.getFriendlyName() + "!";
     }
     return str + "!";
   }
 }
 

2. Instanciate your class using the jcmsContext variable available in the any jsp and register this new instance using JSON.

  json_bridge.registerObject("MyAjaxClass", new MyAjaxClass(jcmsContext));
 

3. Call your methods from javascript using JSON.

  <script type="text/javascript">
    function saySomething(str) {
      var msg;
      try {
        msg = JcmsJsContext.getJsonRPC().MyAjaxClass.saySomething(str);
      }
      catch(ex) {
        alert(I18N.glp('warn.json.sessiontimeout'));
        return;
      }
      alert(msg);
    }
  </script>
  <a href="#" onclick="saySomething('Hello'); return false;">Say Hello</a>
