使用函数close运行的代码：

function openModal(id) {

    //Get the screen height and width
    var maskHeight = $(document).height();
    var maskWidth = $(window).width();

    //Set heigth and width to mask to fill up the whole screen
    $('#mask').css({'width':maskWidth,'height':maskHeight});

    //transition effect
    $('#mask').fadeIn(1000);
    $('#mask').fadeTo("slow", 0.8);

    //Get the window height and width
    var winH = $(window).height();
    var winW = $(window).width();

    //Set the popup window to center
    $(id).css('top', winH / 2 - $(id).height() / 2);
    $(id).css('left', winW / 2 - $(id).width() / 2);

    //transition effect
    $(id).fadeIn(2000);

    $('.window .modalClose').click(function (e) {
        e.preventDefault();

        $('#mask').hide();
        $('.window').hide();
    });     

    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });         

}

$(document).ready(function() {

    $('a[name=modal]').click(function(e) {
        //Cancel the link behavior
        e.preventDefault();
        openModal($(this).attr('href'));
    });

    openModal('#modalDialog');

});
