Child classes may override this method to declare what PHP callbacks should
be attached to the events of the [[owner]] component.
The callbacks will be attached to the [[owner]]'s events when the behavior is
attached to the owner; and they will be detached from the events when
the behavior is detached from the component.
The callbacks can be any of the following:
- method in this behavior: 'handleClick', equivalent to [$this, 'handleClick']
- object method: [$object, 'handleClick']
- static method: ['Page', 'handleClick']
- anonymous function: function ($event) { ... }
The following is an example:
php
[
Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]
public function events()
{
$owner = $this->owner;
if ($owner instanceof Controller) {
