This plugin allows you to react when an element is in the viewport. You need throw confetti when the user scroll and see an element?, so this plugin is for you!
npm install jquery-is-in-viewport --save
// or
yarn add jquery-is-in-viewport
// or
bower install jquery-is-in-viewport
$('.block').isInViewport(function (status) {
if (status === 'entered') {
$(this).addClass('throw-confetti')
}
if (status === 'leaved') {
$(this).removeClass('throw-confetti')
}
})
Status can be 'entered' or 'leaved'.
