We can do the above task (executing a script when a user navigates to a page in HTML) by using "onpageshow Event". Before we jump into the examples let’s look into the definition and usage of onpageshow event in HTML.

  • We have written an alert() method inside the function. So whenever the user tries to navigate to a page the onpageshow event will be triggered.

<!DOCTYPE html> <html> <head> <title>Execute a script when a user navigates to a page in HTML?</title> </head> <body onpageshow="navigate()"> <h2>Execute a script when a user navigates to a page in HTML?</h2> <p><b>Note:</b> The <strong>"onpageshow"</strong> event in HTML will not supported in Internet Explorer 10 and before versions.</p> <script> function navigate() { alert("Welcome to the page!"); } </script> </body> </html>
