Property Details
Event names mapped to what should be specified in .on().
If empty, it is assumed that event passed to clientEvents is prefixed with widget name.
The event handlers for the underlying jQuery UI widget.
Please refer to the corresponding jQuery UI widget Web page for possible events.
For example, this page shows
how to use the "Accordion" widget and the supported events (e.g. "create").
Keys are the event names and values are javascript code that is passed to the .on() function
as the event handler.
For example you could write the following in your widget configuration:
'clientEvents' => [
'change' => 'function () { alert('event "change" occured.'); }'
],

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.
