I can't get the value of the variable

mdmunir say

Event::$data not used like that. Its only receive value from on() method. http://www.yiiframework.com/doc-2.0/yii-base-event.html#$data-detail
Create your own event class.

class MyEvent extends Event
{
public $params;
}

// ############
$this->on('event_name',function($event){
echo $event->params;
});

$this->trigger('event_name',new MyEvent(['params'=>'param value']));

If you using Event::$data, its always set to value of parameter on(). http://www.yiiframework.com/doc-2.0/yii-base-component.html#on()-detail

1, $this->trigger(self::EVENT_POSITION_UPDATE, new Event([
'data' => $this->_positions[$position->getId()],
]));
本来想在论坛里问，可是忘了密码了，试了好久都验证码不对，找不回密码
请问上面的用法对不，为什么data为null，取不到数据

I was going to ask in the forums, but I forgot the password

Trying for a long time, the verification code is wrong, I can't get my password back

the above code,is that right? The value of the 'data' is null,

I can't get the values of variables

2,
$this->on(self::EVENT_POSITION_PUT, ['frontend\compoments\Evee','aa'],$this->_positions[$position->getId()]);

像这样用的话是取的到的
In the examples above,I can get the value of the variable
