TestBug

This example demonstrates an interactive select dropdown component built with Ember.js. The component, defined in `components.select-dropdown.js`, maintains a bound `value` property and synchronizes it with the selected `<option>` element using observers and the `didRender` lifecycle hook. It supports plain string arrays or objects with `value` and `label` keys, with an optional empty default option. The application controller supplies a static `dropdownOptions` list, and the template renders the dropdown with a bound selection. The code relies on Ember’s component lifecycle methods (`didReceiveAttrs`, `didInsertElement`, `didRender`) and the `change` event handler to propagate user selections back to the controller.

Ember Virtual List Component

This example demonstrates an Ember.js virtual list component that renders only the items visible within a scrollable container, improving performance for large datasets. It uses the Ember component API with computed properties and Handlebars templates, along with jQuery for scroll event handling and DOM measurements. The code generates a list of 1,000 random names and positions each row absolutely within a scroller element. As the user scrolls, the component calculates start and end indices based on scroll offset and container height, updating the visible items dynamically.

Ember Virtual List Component

This example demonstrates the Ember Virtual List Component, a UI pattern for efficiently rendering large datasets by only displaying items currently in view. As the user scrolls through a container of 1,000 generated name entries, the component calculates the visible range and renders only those rows. It uses an Ember component with computed properties like `startIndex` and `endIndex` to determine which items to slice from the model, and applies absolute positioning via inline styles. The implementation relies on jQuery for scroll event binding and Ember's template compiler for dynamic component rendering.

Ember Starter Kit

This example demonstrates a virtual scrolling list built with the Ember framework. It renders 1,000 items but only displays a small visible subset within a fixed-height, scrollable container, using absolute positioning to place items at their correct vertical offsets. The component calculates visible indices and offsets based on the current scroll position, updating the display dynamically. The code uses Ember’s `Component`, `Route`, and `Handlebars.SafeString` APIs, along with jQuery for scroll event binding, and the data is a generated list of names.

Ember Virtual List Component

This example demonstrates an Ember Virtual List component that efficiently renders a scrollable list of 1,000 generated names by only displaying rows currently visible in the viewport. The component uses Ember’s computed properties to calculate start and end indices based on the scroll offset, and renders rows as absolutely positioned elements inside a scrollable container. The implementation relies on Ember.Component, Handlebars templates, and the `didInsertElement` lifecycle hook to bind scroll events and update the visible row set dynamically.

Ember rest spread

This example demonstrates how Ember’s component lifecycle manages the asynchronous spread of REST API data into a live-updating visualization. It shows data flowing from a server through Ember Data models, then being transformed and rendered as dynamic visual elements. The code uses `babel-plugin-transform-object-rest-spread` to enable modern object spread syntax within Ember CLI’s build pipeline, while the `.eslintrc` config enforces ES2017 parsing with experimental support for rest/spread properties. The rendering relies on Ember’s template and component system to bind incoming attributes to visual marks, though no specific charting library is visible. The approach focuses on state management and prop drilling rather than direct DOM manipulation, with data sourced from an unspecified Ember adapter.

Ember Virtual List Component

This example demonstrates a virtual scrolling list built with Ember.js that efficiently renders only the visible subset of a 1000-item dataset. The component tracks the scroll container's offset, calculates which rows fall within the viewport, and positions them absolutely inside a taller spacer div that represents the full list height. The rendered rows are green rectangular bars with white borders and text labels, styled via custom CSS classes. Debug information displays live scroll offset, visible element count, and computed start/end indices, using Ember's Handlebars templating and component lifecycle hooks like `didInsertElement` and property bindings.

Contextual Components for Drop Downs?

This example shows how to build a contextual dropdown component using Ember 2.9 and its component APIs, including `{{yield}}` with a hash, `(component ...)`, and `(action ...)`. The `drop-down` component yields a trigger and content subcomponent, passing the `closed` state to the content and a toggle action to the trigger. A button toggles a CSS class that hides or shows the content paragraph. The code uses Ember.Component extensions, `classNameBindings`, and `toggleProperty` to manage the open/closed state.
