Answer 1

Just write down like $("#psharebutton").attr('display','') or $("#psharebutton").attr('display','block').

function dolinkedin(url, title, summary, source) {
        $(".smbutton").addClass("buttonDisabled");
        $("#linklinkedin").removeClass("buttonDisabled");
        $("#psharebutton").attr('display','');

        parent.sizeFancybox();
    }
