Developers often depend on custom JavaScript and fragile Document Object Model (DOM) manipulation to hide fields, update values, or trigger actions, an approach that easily breaks when page structures change, drives up maintenance costs, limits scalability, and leads to inconsistent experiences. Power Pages Client APIs address these challenges by offering stable, documented, and supported methods to interact with components, reducing risk, improving maintainability, and accelerating development.
The Power Pages Client APIs (Preview) provide a JavaScript interface for controlling UI components and performing operations on your Power Pages site.
Key features include:
Form API: Retrieve forms by ID, manage their visibility, and interact with controls.
List API: Access lists, toggle their visibility, and retrieve HTML elements.
User API: Handle authentication actions like sign-in and sign-out.
Web API: Use OData-compliant methods to create, retrieve, and query records.
These APIs allow you to dynamically update UI elements, manage data, and create tailored user experiences without reloading the page.
Business Value:
This feature empowers you to create richer, interactive Power Pages experiences without complex server-side logic. By using client-side APIs for forms, lists, and authentication, you’ll customize faster, control UI dynamically, and handle real-time data with ease. This means delivering tailored experiences, improving usability, and accelerating development, all while keeping your sites secure and consistent.
