标签: javascript jquery cookies

我正在尝试检查用户是否有cookie,如果没有,则运行jQuery代码。

这是我到目前为止所做的,但它不起作用......我有一个语法错误。

<code>
    <script type="text/javascript">

$(document).ready(
if($.cookie('car') == undefined){
function() {    

        var id = '#dialog';

        //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);     

    //if close button is clicked
    $('.window .close').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

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

    //if mask is clicked
    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });     

}});
</script>
