JavaScript - Popups not working -


i tried using alert() , confirm() in javascript.

<!doctype html> <html> <head> <title> website </title> </head> <body> <br/> <br/> <br/> <br/> <h2 align=center>my website</h2> <p align=center> <button onclick=“myfunction()”>click enter</button> </p>         <script type=text/javascript> function myfunction() {     alert(“u sure?”); } </script> </body> </html>
