阻止用戶界面無法正常工作

Question

爲什麼此代碼無法運行？ 我在將文件下載到fileDownloadToken時設置了cookie。如果不是null，則EXEC finishdownload檢查...

<script type="text/javascript"> 
    var fileDownloadCheckTimer; 
    function blockUIForDownload() { 
     if (IsCookiesEnable()) { 
      var token = new Date().getTime(); //use the current timestamp as the token value 
      $('#token').val(token); 
      $.blockUI{ message: '', fadeIn: 0 };); 
      fileDownloadCheckTimer = window.setInterval(function() { 
       var cookieValue = $.cookie('fileDownloadToken'); 
       // alert(cookieValue); 
       if (cookieValue != null) 
        finishDownload(); 
      }, 1000); 
     } 
    } 

    function IsCookiesEnable() { 
     var cookieEnabled = (navigator.cookieEnabled) ? true : false; 

     if (typeof navigator.cookieEnabled == "undefined" && !cookieEnabled) { 
      document.cookie = "testcookie"; 
      cookieEnabled = (document.cookie.indexOf("testcookie") != -1) ? true : false; 
     } 
     return (cookieEnabled); 
    } 

    function finishDownload() { 
     //window.clearInterval(fileDownloadCheckTimer); 
     $.cookie('fileDownloadToken', null); 
     $.unblockUI(); 
    }

變化

$.blockUI{ message: '', fadeIn: 0 };); 

到

$.blockUI({ message: '', fadeIn: 0});
