EJsWidget

EJsWidget a behavior class providing a structured client-side behavior representation for Yii widgets.
It also includes an experimental part supporting "self actions" of widgets, by making the controllers' "action provider" ability more handy.

See EJsWidget in action below:

ETestWidget: minimal example, without inline actions

call hello() method 
<?php
class ETestWidget extends CWidget {
    public $name;
 
    public function init() {
        parent::init();
        EJsWidgetBehavior::prepare($this);
        $this->render('index');
    }
 
    public function jsAttributes() {
        return array_merge(parent::jsAttributes(), array(
            'name'
        ));
    }
}

ECalculatorWidget: uses inline actions

= 
<?php
class ECalculatorWidget extends ESimpleActionWidget {
    
    public $num1 = 0;
    public $num2 = 0;
 
/**
 * INitialization
 **/
    public function init($widgetAction = false) {        
        parent::init();
 
        //Full widget initialization IF the current request isn't a self-request
        if (!$widgetAction) {
            EJsWidgetBehavior::prepare($this);
            $this->render('index');
        }
    }
 
/**
 * Defining which params to be passed to the js instance - these ones will be recent in the widget's "opt" object
 * Can be set only widget attribute names or arbitrary name=>value pairs
 **/
    public function jsAttributes() {
        return array_merge(parent::jsAttributes(), array(
            'num1','num2'
        ));
    }
    
/**
 * UI helpers
 **/
    public function num1() {
        return CHtml::textField($this->id . '_num1', $this->num1);
    }
 
    public function num2() {
        return CHtml::textField($this->id . '_num2', $this->num2);
    }
 
    public function bAdd() {
        return CHtml::button('add', array(
            'id' => $this->id . '_add',
            'onclick'=>$this->jsObj() . '.add()'
        ));
    }
    
/**
 * Widget self-actions
 * 
 **/
    public function actionAdd() {
        echo (int)$this->num1 + (int)$this->num2;
    }
 
}

EFancyCalculatorWidget: inline actions + inheriting

= 
<?php
require_once(__DIR__ . '/../ecalculator/ECalculatorWidget.php');
 
class EFancyCalculatorWidget extends ECalculatorWidget {
    
    public static function getJsName() {
        return 'efancycalculatorwidget.js';
    }
    
    public function init($portletAction = false) {
        parent::init($portletAction);
    }
 
 
    //UI
    public function bMult() {
        return CHtml::button('mult', array(
            'id' => $this->id . '_mult',
            'onclick'=>$this->jsObj() . '.mult()'
        ));
    }
 
    //Actions
    public function actionMult() {
        echo (int)$this->num1 * (int)$this->num2;
    }
 
}
