Binds a high-priority interaction that defers any .animate()
or .mutate()
task that are executed elsewhere in the app. This protects any interaction related UI changes from jank.
sequencer.on(element, 'scroll', function(e) {
sequencer.mutate(...);
});
sequencer.on(element, 'click', function(e) {
return sequencer.animate(function() {
element.classList.add('grow');
return element;
});
});
sequencer.on(element, 'click', function(e) {
return sequencer
.animate(() => {
element.classList.add('grow');
return element;
})
.animate(() => {
element.classList.add('shrink');
return element;
})
});
sequencer.off(element, 'click', callback);
.animate()
or .mutate()
tasks inside the .interaction()
callbacks are run instantly and not deferred.Should contain any animation/transition code and return the target element.
sequencer
.animate(() => {
element.style.transform = 'translateY(100%)');
return element;
})
.then(() => {
// transition/animation end
});

var li = document.createElement('li');
