Question

jquery

$("#go").click(function() {
        $.post("i/go.php", $("#form").serialize());

        var code= ''; 

        $("section").empty().html(code);
});

go.php accepts POST data, then displays some text in <section>.
How to get <section> after sending POST data and display it on this page?

Answer 1

You are not handling the response at all, just sending the request:

$.post("i/go.php", $("#form").serialize(), 
    function(data) {
       // do something with data
       $("#some_div").html(data);
    }
);
