(Recommended listening; please mentally replace the word 'smooth' with 'scroll'.)
ScrollOperatorMixin
This will save the scrolling position of a route. When the route is re-entered, it will automatically scroll to the previously saved position only if accessed by the browser's forward and back buttons. Accessing the route via link-to or address bar will not trigger this behavior. This is by design in order to more closely emulate the HTML experience.
import ScrollOperatorMixin from 'ember-scroll-operator/mixins/scroll-operator';
export default Ember.Route.extend(ScrollOperatorMixin, {
// If any of the following methods are implemented in your route, be sure to
// include a call to the parent to make sure the mixin is included.
activate() {
this._super(...arguments);
// existing code
},
deactivate() {
this._super(...arguments);
// existing code
},
beforeModel() {
this._super(...arguments);
// existing code
},
setupController() {
this._super(...arguments);
// existing code
},
});
ResetScrollMixin
A simple mixin to ensure that a route is always scrolled to the top when accessed.
import ResetScrollMixin from 'ember-scroll-operator/mixins/reset-scroll';
export default Ember.Route.extend(ResetScrollMixin, {
// If the following methods are implemented in your route, be sure to include
// a call to the parent to make sure the mixin is included.
activate() {
this._super(...arguments);
// existing code
},
});
