_hs: counter

[r3sist]

Dear Community,
Dear Developers,

I have a hyperscript problem.

I would like to make an intersection event, which should be triggered only once (when an HTML element became visible - basically image lazy loading). On the The event handler Feature documentation page there is a [<count>] parameter mentioned, probably I should set it to 1 in a simple _hs expression after a simple command (on click 1 set...).

But this won't work:

data-script="on intersection(intersecting) having threshold 0.1 1 set {src: 'newSrc'} on me"
                                                                ^ is this the right place for count?

I've tried it without having threshold 0.1 but in that case, all the images will be loaded immediately regardless they're in a non displaying element. Without the counter it redownloads every image on every intersection. I've tried halt on the end also, but it didn't help.

Do you have any suggestions?
Thank you.

Sorry if this place is not for hyperscript anymore :)
