focus events are listened, component is notified when browser / page is opened again:
useEffect(() => {
//Add a listener on the window object
window.addEventListener('focus', onFocus)
//Clean listeners
return () => {
window.removeEventListener('focus', onFocus)
}
}, [])
const onFocus = (e) => {
if (e.) { // <--------------
return
}
dispatch(
log({
text: 'onFocus get called',
})
)
callBuyTicket2()
}
But selecting other option
in select
item on the page will fire also focus
event. Is it a way to filter those events out?
I think you have to use a state and the onblur event.
const [isCurrentlyInPage, setIsCurrentlyInPage] = useState(true)
useEffect(() => {
//Add a listener on the window object
window.addEventListener('focus', onFocus)
window.addEventListener('blur', onBlur)
//Clean listeners
return () => {
window.removeEventListener('focus', onFocus)
window.removeEventListener('blur', onBlur)
}
}, [])
const onFocus = (e) => {
if(!isCurrentlyInPage){
setIsCurrentlyInPage(true)
//your code
}
}
const onBlur = () => {
setIsCurrentlyInPage(false)
}
