Access different widgets inside the widget event listeners | CQ5 / AEM

To access widgets inside the event listeners of any widget, follow the below step.

1. Get the "dialog" object first.  
1. var dailogObject = this.findParentByType('dialog');
2. This will return the dialog object associated with your compoent dialog. Then look for the corresponding widget by invoking 
1. var titleField = dailogObject .getField('./jcr:title'); 
3. The above function looks for a widget by name './jcr:title' and returns the widget object associated.

Use case scenario.

Let's create a component dialog with 2 widgets (Pathfield, TextField). 

use case 1: if author selects any link URL then the corresponding title of the page should be set into the TextField widget.

Below steps can be followed to achieve this.

1. create a component dialog with two widgets.
1. One path field with name "./path" and xtype is  "pathfield"
2. Text field with name "./title" and xtype is "textfield" 
2. Attach a listener to the path field. And add "dialogclose" event to the listener. 
3. The javascript function for the above event can be written as below.

4. 	function(){
   	var componentDialog = this.findParentByType('dialog'); // returns the dialog object
   	var titleWidget = componentDialog.getField("./title");
   	var selectedPath = this.value;// returns the selected path from the path field
   	//Can write a remote service which returns the title of any path selected
   	$.get("/someRemoteService",{'path':selectedPath}).done(function(data){
   	titleWidget.setValue( data );
   	});
   	}
