event on hide element

Webix JS
#1

Hello. How i can attach event when i try $$(id).hide() && $$(id).show()?
This events i find only for window, but what about another elements?

#2

you can catch view showing using onViewShow event

#3

thx, but what about view hiding?

#4

There is no function for the hide view.
One solution is to watch if the view is not visible.

on: {
onViewShow(){
//interval check if view is not visible
const $this = this;
const close_id = setInterval(() => {
if (!$this.isVisible()) {
alert(123);
// required
clearInterval(close_id);
}
}, 100);
}
}
