in my js method request1, how can I submit to call the PHP function request? on this page
<?php
function request(){
}
?>
<html id="html">
<button id="btn_click" onclick="request1()">click</button>
</html>
<script type="text/javascript">
function request1(){
document.write("<h1>been clicked</h1>");
}
</script>
