Question

從回調函數得到選擇我怎樣才能選擇傳遞給主函數

$('.file_upload').uploadify({ 

     'uploader' : 'uploadify/uploadify.swf', 
     'script' : 'uploadify/uploadify.php', 
     'cancelImg' : 'uploadify/cancel.png', 
     'folder' : 'uploads', 
     'auto'  : true, 
     'buttonText': 'Upload a new file', 
     'onComplete' : function(event, ID, fileObj, response, data) { 
      //alert(fileObj.filePath); 

      //get the uploaded file txt and add it to the textbox 

      console.log(fileObj.filePath); 
      $.get('readfile.php?file='+fileObj.filePath, function (data) { 



      }); 

     // here I want to access the element the function called on 
     //$(this).parent().parent().find('textarea').val('this'); 

     } 
});

原始的元素是event.target下可用：

$('.file_upload').uploadify({ 
    'onComplete' : function(event, ID, fileObj, response, data) { 
     // Wrap event.target in jQuery: $(event.target) 
     $(event.target).parent().parent().find('textarea').val('this'); 
    } 
});

你可以將它保存爲一個變量uploadify前：

var _file_upload = $('.file_upload'); 

//Then you can just do: 
_file_upload.jQueryStuffHere();
