How to merge data attributes in ajaxSubmitButton?

Question

JavaScript

Good afternoon, there is such a bandura:

echo CHtml::ajaxSubmitButton
(
    $model->isNewRecord ? 'Добавить номера' : 'Обновить',

    Yii::app()->createUrl('sadmin/hotels/ajaxCreate'),
    [
        'type'=>'POST',
        'data'=>'js:$("#add-user-form").serialize()',
        // Yii::app()->request->csrfTokenName => Yii::app()->request->csrfToken
        'success'=>'js:function(data)
        {alert(data);}',
    ],

How can I correctly syntactically merge into data - Yii::app()->request->csrfTokenName => Yii::app()->request->csrfToken and 'js:$("#add-user-form"). serialize()' ? So that it and then fly away.

If without js serialization, then it is clear:

'data'=>
[
        Yii::app()->request->csrfTokenName => Yii::app()->request->csrfToken
]

And in my case I'm having a hard time

Answer 1

since serialize() returns a string, then you can do

'js:$("#add-user-form").serialize()+"&'.Yii::app()->request->csrfTokenName.'='.Yii::app()->request->csrfToken.'"'
