The onpageshow event occurs when a user navigates to a website. This event is quite similar to onload event but it occurs after the onload event. It occurs every time, when the page is loaded whereas the onload event does not occur when the page is loaded from the cache.

When a page is loaded or restored, it triggers and provides session history information. It is also useful for executing actions related to page visibility and loading states and enables developers to handle scenarios like page refresh or back-forward navigation.

Syntax: 

<element onpageshow = "script"> 

Supported Tags: 

Note: This event contains a single attribute script. The script is to be run on the onpageshow event. This event is used within the body tag.
