Popup.template.events({ 'click .js-back-view'() { Popup.back(); }, 'click .js-close-pop-over'() { Popup.close(); }, 'click .js-confirm'() { this.__afterConfirmAction.call(this); }, // This handler intends to solve a pretty tricky bug with our popup // transition. The transition is implemented using a large container // (.content-container) that is moved on the x-axis (from 0 to n*PopupSize) // inside a wrapper (.container-wrapper) with a hidden overflow. The problem // is that sometimes the wrapper is scrolled -- even if there are no // scrollbars. This happen for instance when the newly opened popup has some // focused field, the browser will automatically scroll the wrapper, resulting // in moving the whole popup container outside of the popup wrapper. To // disable this behavior we have to manually reset the scrollLeft position // whenever it is modified. 'scroll .content-wrapper'(evt) { evt.currentTarget.scrollLeft = 0; }, }); // When a popup content is removed (ie, when the user press the "back" button), // we need to wait for the container translation to end before removing the // actual DOM element. For that purpose we use the undocumented `_uihooks` API. Popup.template.onRendered(() => { const container = this.find('.content-container'); container._uihooks = { removeElement(node) { $(node).addClass('no-height'); $(container).one(CSSEvents.transitionend, () => { node.parentNode.removeChild(node); }); }, }; });
