uploadify queueData錯誤

Question

我正在使用Uploadify 3.1，並且在單擊上傳按鈕時出現錯誤「未捕獲的TypeError：無法讀取未定義的屬性'queueData'」。以下是我的代碼。不確定是什麼問題。

上傳領域：

<input type="file" name="file_upload" id="file_upload"/> 
<input type="button" class="batchImport" value="Upload Files"/> 

的Javascript：

$(document).on("click",".batchImportElements",function(){ 
     $("#objectDetails").hide().html(""); 
     $("#objectList").show(); 
     $("#objectList").html("<img src="images/loading.gif"/> Loading").show(); 
     $.ajax({ 
      type:"POST", 
      data:{ 
       multiple:1 
      }, 
      url:"/index.php/elements_handler/importElements", 
      success:function(response){ 
       checkResponse(response); 
       $("#objectList").html(response); 

       $("#file_upload").uploadify({ 
        "swf":"/js/uploadify-v3.1/uploadify.swf", 
        "uploader":"/js/uploadify-v3.1/uploadify.php", 
        "uploadFolder":"/uploads/", 
        "auto":false, 
        "multi":true, 
        "height":19, 
        "width":94, 
        "onUploadError":function(file,errorCode,errorMsg,errorString){ 
         alert("The file " + file.name + " could not be uploaded: " + errorString); 
        }, 
        "onUploadSuccess":function(file, data, response){ 
         $.ajax({ 
          type:"POST", 
          data:{ 
           multiple:1, 
           companies_id:companies_id, 
           file:file, 
           data:data, 
           folderPath:1 
          }, 
          url:"/index.php/elements_handler/importElements", 
          success:function(response){ 
           checkResponse(response); 
          } 
         }); 
        } 
       }); 

       $(document).on("click",".batchImport",function(){ 
        $(".batchImport").uploadify("upload"); 
       }); 
      } 
     }); 
    }); 

`

的$('.batchImport')是用來觸發上傳按鈕。任何幫助，將不勝感激。

你爲什麼在與ID file_upload然後調用與類batchImport按鈕控制上傳文件控制創建uploadify？帶有類batchImport的按鈕未作爲uploadify控件設置，因此應該引發錯誤。

// Your code 
$("#file_upload").uploadify({ 
    ....      
}); 

$(".batchImport").uploadify("upload"); 


// Should most likely be 
$("#file_upload").uploadify({ 
    ....      
}); 

$("#file_upload").uploadify("upload");
