implement like/dislike system with no refresh on node js

i'm building a social app with node js and i want when someone click like button to update total likes but without reloading the page! how can achieve this? i tried with ajax call like this:

$('.imgInfo').click(function (e) {
    e.preventDefault();
    var link=$(this).attr('href');
    var fd = new FormData($(this)[0]);
    $.ajax({
        url: link,
        data: fd,
        processData: false,
        contentType: false,
        type: 'GET',
        success: function(data){
        $("body").html(data);
        }
    });
