IonEnd

IonEnd is a JavaScript event handler that is fired when a load request using the XMLHttpRequest (XHR) object, native XMLhttpsrequest, and Fetch API is completed. This event is triggered when the requested resource has finished loading and all associated data has been received.

When IonEnd is fired, it is typically in response to a successful load request, although it can also occur when an error is encountered during the loading process. The event is accessible through the object that triggered it, typically through the event object or the request object used to send the request.

IonEnd is often used in conjunction with other events such as IonLoad and IonError to handle various stages of a load request. By listening for these events, developers can implement custom logic and error handling within their applications.

IonEnd is supported by most modern browsers, although the exact implementation may vary. Developers should be aware that IonEnd is often not fired for resources like basic HTML and CSS files, as these are typically loaded and cached by the browser.

In terms of its use cases, IonEnd is commonly employed in applications that deal with dynamic content loading, such as web pages with dynamic regions or users who upload content directly to the application. Web developers use IonEnd to enforce data consistency, update application state, and trigger actions based on the completion of load requests.
