yii2: Utilizing the power of dynamic calling in widgets

Imagine I have a widget called Widget1;

In the view file, I call this widget like so:

<?= Widget1::widget() ?>

Clicking on an element should trigger a new instance of the widget and execute its JavaScript scripts. However, I am unable to get the script execution to work after an AJAX call.

Answer №1

To implement AJAX functionality in your web application, you can create a call to a controller action that will initialize your widget and execute its JavaScript functions. Here's an example:

//@app/widget/Widget1
class Widget1 extends \yii\base\Widget
{
    public function run()
    {
        echo new JsExpression('function(){ alert("hello,world") }');
    }
}

//@app/controllers/SomeController
public function actionSomeaction()
{
    return Widget1::widget();
}

You can then trigger this action from an AJAX function handling an 'onClick' event using jQuery, for instance:

<script>
    $.post('/some/someaction',function(response){
        response();
    });
</script>
