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. Sample screen shot

Attach listeners to widgets in CQ5 / AEM

Follow the below steps to create or attach listeners (javascript event listeners) to any widget in CQ5 / AEM.

  2. Find out the events which can be attached to a widget. You can find the list of events from the CQ Widget API documentation. Click here to visit.
  3. e.g. The "pathfield" widget has got one event called "dialogclose". This event is fired when user selects any link from the browse field & clicks OK.
  4. To attach this add one property by name "dialogclose" to the listeners node. The value should be any javascript function call. 
    1. e.g. function(){ console.log("You have selected a link in path field"); }
