I tried to refresh some div in my page  with ajax load by using .load() but didn't work.  I have to create new file page that use php to echo my div again.  So Question is Do I have to create new file for echo that div, if I just want to refresh some div in my page?
$("button").click(function(){
    $("#div1").load("currentpage.php");
});
above is not work.
I have to use below code.
$("button").click(function(){
        $("#div1").load("otherpage.php");
    });
