jQuery檢查cookie

Question

我想檢查用戶是否有cookie，如果沒有，運行jQuery代碼。

這是我到目前爲止，但它不起作用...我有一個語法錯誤。

<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>
