In JavaScript programming, location.reload is often used to refresh the page.

window.location.reload(true) //The browser re-requests resources from the server, and the cache tag will not be included in the http request header.

<script>
window.location.reload();
</script>

aa.htm page content:

<input type ="button" value ="刷新" onclick ="aa()"/>
