Hope this will give you an idea of how you can do it:

Page 2

HTML

JS

$("form").submit(function(e){

    e.preventDefault();

    $.post('save_data.php', { new_info:$("#new-info").val() }).done(function(data){
         // Do something if you want to show that form has been sent
    });


});

save_data.php

Page 1

HTML

JS

setInterval(search_after_info, 1000);


function search_after_info() {

    $.get('get_data', function(data) {

        $("#information").html(data);

    });

}
