onpageshow HTML Attribute

The "onpageshow" 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 shown or is about to be shown. 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 onpageshow attribute is used to restart an animation when the page is shown:


<body onpageshow="restartAnimation()">

The onpageshow attribute is used on the body element and it's useful for detecting when the user navigates back to the current page, or when the browser's tab is focused. It can be used to resume animations, start videos or any other background tasks that were paused, in order to improve the user experience and performance.

It's worth noting that the onpageshow 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.
