JavaScript/jQuery - Popup Scrolling

This demo shows two implementations of scrolling in the JavaScript Popup component.

When you click the first Show JavaScript Popup button, a JavaScript Popup with a native scrollbar appears. The component always displays a native scrollbar when the height of the JavaScript Popup's content is greater than that of the JavaScript Popup.

Backend API
$(() => { $('#show-popup-button').dxButton({ text: 'Show Popup', width: 300, type: 'default', onClick() { popup.show(); }, }); $('#show-popup-with-scrollview-button').dxButton({ text: 'Show Popup', width: 300, onClick() { popupWithScrollView.show(); }, }); const popup = $('#popup') .dxPopup({ width: 360, height: 320, visible: false, title: 'Downtown Inn', hideOnOutsideClick: true, showCloseButton: true, toolbarItems: [ { widget: 'dxButton', toolbar: 'bottom', location: 'center', options: { width: 300, text: 'Book', type: 'default', stylingMode: 'contained', onClick() { popup.hide(); }, }, }, ], }) .dxPopup('instance'); const popupWithScrollView = $('#popup-with-scrollview') .dxPopup({ width: 360, height: 320, visible: false, title: 'Downtown Inn', hideOnOutsideClick: true, showCloseButton: true, toolbarItems: [ { widget: 'dxButton', toolbar: 'bottom', location: 'center', options: { width: 300, text: 'Book', type: 'default', stylingMode: 'contained', onClick() { popupWithScrollView.hide(); }, }, }, ], contentTemplate() { const $scrollView = $('<div/>'); $scrollView.append($('<div/>').html(htmlContent)); $scrollView.dxScrollView({ width: '100%', height: '100%', }); return $scrollView; }, }) .dxPopup('instance'); });

A click on the second Show JavaScript Popup button also displays a JavaScript Popup with a scrollbar, but this scrollbar belongs to the ScrollView component. This implementation is more flexible. For example, you can enable right-to-left representation or scroll the content to a specific position. For more information about the available options, refer to the ScrollView API section.

To implement the second solution, follow the steps below:

  1. Wrap the content in the ScrollView component and place it in the JavaScript Popup container.

  2. Set the height and width of the ScrollView to 100% of the popup content area.
