[VizStudy]Week6: Menus with React

Menus with React

This example shows a pet-selection interface built with React, where users choose from a dropdown menu of goldfish, dog, or cat. It demonstrates state management with React’s `useState` hook, rendering a `<select>` element and dynamically highlighting the selected option. The app uses ReactDOM to render the component tree, with the dropdown options defined as an array of value-label pairs. The selected value is logged to the console, and the interface updates live as the user changes the selection.

This example demonstrates interactive dropdown menus built with React, showing a pet selection interface where users choose from options like goldfish, spider, and hamster. The React component `Dropdown` manages the menu, while `useState` tracks the selected value and updates it through an `onSelectedValueChange` callback. The code uses React 16.9.0 and ReactDOM to render the interface, with options defined in a static array in `index.js`. The example highlights how React handles form state and event-driven UI updates in a visualization context.

This example demonstrates how to build interactive dropdown menus in React. It renders a pet selector with options for goldfish, dog, cat, and parrot, using React’s `useState` hook to track the selected value and update the UI on change. The `Dropdown` component maps over a hardcoded options array, creating `<select>` and `<option>` elements, with an initial value set to “cat.” The code uses React 16.9 and ReactDOM from unpkg, with the dropdown styled via CSS in the HTML file.

This example demonstrates a simple pet-selection menu built with React, displaying a dropdown list of six animal options and logging each chosen value to the console. It shows how React state manages the selected option through the `useState` hook, with the `Dropdown` component receiving options, an ID, and a change handler as props. The rendering uses ReactDOM to mount the app into the DOM, while the dropdown’s `onChange` event triggers updates to the selected value. The code includes inline HTML styling for large label and select text, and relies on React 16.9 from a CDN.

This example demonstrates a pet-selection menu built with React, displaying a dropdown that lets users choose from six animals and updates a displayed value in response. It shows how a reusable `Dropdown` component manages state through React hooks, specifically `useState` for tracking the selected value and `onSelectedValueChange` to handle user input. The interface renders via `ReactDOM.render`, with options defined in a JavaScript array and styled using inline CSS. The code uses React 16.9.0 from a CDN, illustrating a controlled component pattern for interactive menu selection.

This example shows a pet-selection menu built as a React component, demonstrating how to manage and update a dropdown’s state. The `Dropdown` component renders a native `<select>` element, mapping an array of pet options into `<option>` tags. The main `App` component uses React’s `useState` hook to track the selected value, initially set to “goldfish,” and passes both the current value and an `onSelectedValueChange` callback to update it on user interaction. The UI is styled with large labels and select text, and the example runs in a browser using ReactDOM to mount the app.

This example shows a React application that renders a simple dropdown menu for selecting a pet from a list of six options (dog, cat, hamster, parrot, spider, goldfish). The current selection is logged to the console and displayed as the menu’s default value. The code uses `useState` for state management, a custom `Dropdown` component built with React’s `select` and `option` elements, and ReactDOM to render the app into the DOM. The dropdown updates its selected value dynamically through an `onSelectedValueChange` callback.

This example demonstrates a pet selector menu built with React, displaying a dropdown list of six pet options and reflecting the current selection through the label above it. The app uses React’s `useState` hook to manage the selected value, initializing with “hamster”, and updates the UI whenever the user changes the dropdown. It leverages the `Dropdown` component, which renders a native HTML `<select>` element, and the ReactDOM `render` method in `index.js` to mount the app to the DOM. The interface uses React 16.9 from a CDN.
