onpagehide HTML Attribute

The "onpagehide" attribute in HTML is an event attribute that can be added to an element, that when triggered, runs a script when the current page is hidden or is about to be hidden. This attribute is typically used with the Page Visibility API, which allows web developers to know when a page is hidden or visible to the user. The attribute value is a string containing the JavaScript code that should be executed when the event is fired.

For example, in the following code snippet, the onpagehide attribute is used to stop an animation when the page is hidden:


<body onpagehide="stopAnimation()">

The onpagehide attribute is used on the body element and it's useful for detecting when the user navigates away from the current page, or when the browser's tab is closed or minimized. It can be used to pause animations, stop videos or any other background tasks that are running, in order to save resources and improve performance.

It's worth noting that the onpagehide attribute is supported by most modern browsers, but not all, so it's important to check the browser compatibility before using it in your website.
