Handling Forms, Payloads, and Live Inputs in Fitz LiveViews
Discover how real user inputs like text fields and selections flow into your handlers using Fitz LiveViews.

- Parts 1 and 2 previously covered the basic pitch and counter implementation.
- Real user interfaces require handling text inputs, selections, and form fields.
- Use @input for every keystroke and @change on blur or selection events.
- Current values are delivered directly to handlers inside payload["value"].
Parts 1 and 2 covered the pitch and the counter. A counter only reads plus one or minus one with no data flowing in. However, real user interfaces take actual input such as text, selections, and form fields. This article explores how that data successfully reaches your application handlers.
For a control that reports information as you type or upon making a selection, the @input attribute captures every single keystroke while @change triggers on blur or selection, delivering the current value straight into payload["value"].
Managing real-time inputs within a Fitz LiveViews architecture significantly reduces client-side complexity. Developers do not need to manually write separate JavaScript event listeners to scrape DOM elements on every keystroke. Instead, capturing input events natively through payloads streamlines state synchronization, making it ideal for responsive web applications.
Wire it directly into a main.fitz file, using the exact same shape as the counter seen in part two, and your application will run seamlessly without relying on heavy client-side frameworks.
If typed events without a client framework sound appealing, consider starring the repository. Stay tuned because the next step will feature a real, working application.
