Is there a better way to get the target of a event as a HTMLElement?

val iframeDocument = element.contentWindow?.document
iframeDocument?.body?.addEventListener("mouseup", callback = { event ->
    val target = event.target?.unsafeCast<HTMLElement>()!!
})

It will probably fail. Not all event targets are elements.

Check not null only (original)

val target = event.target?.unsafeCast<HTMLElement>()!!

Unsafe mode:

val target = event.target.unsafeCast<HTMLElement>()

Safe mode:

val target = event.target as?HTMLElement
if (target != null) {
    // action
}

But there is no option to check the type before casting is there? @Robert Jaros

[turansky]

val target = event.target
if (target is HTMLElement>) {
    // action
}

@turansky That aint working because of the type of event.target is public external abstract class EventTarget
