Hello, I made this code to test, since it does not work
<script>
$(document).ready(function(){
$("#button").click(function(){
$("#div").load('teste.php');
});
});
</script>
<input type="button" id="button" name="button" value="ADD PAGE">
<div id="div" name="div"></div>
test.php
<?php>
echo 'teste';
?>
