Event in Vue for rendering a specific div?

As in the Vue is hung or simulated event of the appearance/rendering of any block?
I have a unit condition v if="" necessary to see if this unit appeared, to execute a certain script.
Without components it is necessary to make(I think there mounted it would be possible to cram)

computed: {
 isBlockVisible() {}
watch: {
 isBlockVisible() {}
I thought about that as thought there's some event "@show"=the"handle")

@Meggie.Spenc, don't remember that DOM was the event of the appearance of the element - Narciso.Von commented on April 7th 20 at 11:05
