Yii2 ajax module with active control from server side. Most of existing ajax modules for Yii2 use javascript logic. yii2-ativeresponse is controlled from the server side. All actions you add in PHP controller will be executed with corresponding jQuery function. See Usage for details.

Installation

The preferred way to install this extension is through composer.

Either run

$ php composer.phar require srusakov/yii2-ativeresponse "dev-master"

or add

"srusakov/yii2-ativeresponse": "dev-master"

to the require section of your composer.json file.

Usage

Attach yii2-ativeresponse to your layout file

ActiveResponse::registerAssets($this);

this will register all necessary javascript files and create global javascript variables.

Call server (without parameters)

<?= Html::a('ActiveResponse Button', null, [
    'href'=>'javascript:void(0);',
    'class' => 'btn btn-success',
    'onclick'=>"callAR('controller/action');"]) ?>

Call server (pass form as parameters)

<form id="theForm" name="theForm" onsubmit="callAR('controller/action', $('#theForm').serializeObject())">

var parameters = $('#theForm').serializeObject();
parameters.your_parameter = 'your value';
callAR('controller/action', parameters);

Call server (with callback)

callAR('controller/action', $('#theForm').serializeObject(), function() {
    alert('Callback called!');
});

Server side

class controllerController extends Controller {
    public function actionAction()
        {
            $ar = new \srusakov\activeresponse\ActiveResponse();

            // show standart browser's alert
            $ar->alert('called from PHP');

            // assign html to div
            $ar->html('div_id', $this->render('view'));

            // modify attribute
            $ar->attr('element', 'data-pjax' '0');

            // assign value to element
            $ar->val('element', 'new value');

            // modify css
            $ar->css('element', 'cssattr', 'value');

            //redirect
            $ar->redirect('/new_page.php');

            // evaluate javascript
            $ar->script("alert('wow!')");

            // and much, much more...
            $ar->focus('element');
            $ar->addClass('element', 'class');
            $ar->removeClass('element', 'class');
            $ar->show('element');
            $ar->hide('element');
            $ar->fadeIn('element');
            $ar->fadeOut('element');

            return $ar;
        }

Using ActiveResponse with DataGrid widget

Example with Delete button inside DagaGrid's ActionColumn

    Pjax::begin(['options' => ['id' => 'pjax-container']]);
    echo GridView::widget([
        ...
        'columns' => [
            [
                'class' => ActionColumn::className(),
                'template' => '{delete}',
                'deleteOptions' => ['data-pjax' => 0, 'class' => 'action-delete'],
                'urlCreator' => function($action,$model,$key,$index) {
                    return  ["/controller/{$action}", 'id'=>$model->id];
                },
            ],


<script type="text/javascript">
<?php ob_start() ?>
$(document).ready(function() {
    $('body').on('click', '.action-delete', function(e){
        var href = $(this).attr('href');
        var message = $(this).data('confirm');
        if (typeof(message) !== 'undefined' && confirm(message)) {
            callAR(href);
        }
        return false;
    });
});
<?php $this->registerJs(ob_get_clean()) ?>
</script>

And PHP Code inside Controller

public function actionDelete($id=null)
{
    $ar = new \srusakov\activeresponse\ActiveResponse();
    $model = Model::findOne(['id' => $id]);
    if ($model) {
        $model->delete();
    }
    $ar->script("$.pjax.reload({container:'#pjax-container'});");
    return $ar;
}
