onpopstate HTML Attribute

The "onpopstate" attribute in HTML is an event attribute that can be added to an element, that when triggered, runs a script when the user navigates the browser's history. 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 onpopstate attribute is used to update the page content when the user navigates the browser's history:


<body onpopstate="updatePageContent()">

The onpopstate attribute is typically used with the History API, which allows web developers to manipulate the browser's history and create a more seamless experience for the user. It can be used to update the page content, change the URL displayed in the address bar, or to perform other actions based on the user's navigation.

It's worth noting that the onpopstate 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.
