Enum virtual_node::event::ManagedEvent

pub enum ManagedEvent {
    Delegated(EventHandler),
    NonDelegated(EventHandler, Rc<dyn AsRef<JsValue>>),
}

An event that to be managed by the PercyDom.

Variants

Delegated(EventHandler)

Every kind of delegated event, such as onclick, has a single event listener attached to the PercyDom’s mount. When that listener is called, it looks up the proper ManagedEvent::Delegated event to call.

NonDelegated(EventHandler, Rc<dyn AsRef<JsValue>>)

For non delegated events, an event listener is attached to the DOM element using .add_event_listener(); That event listener is an EventWrapper, which in turn will find and call the EventAttribFn. This setup allows us to replace the EventAttribFn after every render without needing to re-attach event listeners.
