罚款上传与格式化代码的问题，事件

Question

我需要有多个事件与fineuploader实例相关联，但我不知道如何去做。不能在fineuploader属性中添加它们吗？是不是完整的事件，然后调用onComplete？有一个例子存在吗？另外，我对关闭括号的数量感到困惑，等等。当我最初剪切和粘贴这个代码时，还有一个额外的）};那个坐在外面。我删除了这一点，但我不确定这是否很酷或不是真正的代码。任何帮助表示赞赏，因为我已经玩了几个小时。此代码以外的部分变量已设置。

$(document).ready(function() { 

    var controlType = '@Model.ControlType'; 
    var surveyItemResultId = @Model.Results[0].SurveyItemResultId; 
    var itemId = @Model.SurveyItemId; 
    var instance = @Model.Results[0].SurveyInstanceID; 
    var loopingCounter = 0; 

    var fineuploader = $('#files-upload').fineUploader({    
     request: 
     { 
      endpoint: '@Url.Action("UploadFile", "Survey")', 
      customHeaders: { Accept: 'application/json' }, 
      params: { 
       surveyInstanceId: (function() { return instance; }), 
       surveyItemResultId: (function() { return surveyItemResultId; }), 
       itemId: (function() { return itemId; }), 
       loopingIndex: (function() { return loopingCounter++; }) 
      }    
     }, 
     validation: { 
       acceptFiles: ['image/*','application/pdf','text/csv'] , 
       allowedExtensions: ['jpeg', 'jpg', 'gif', 'png', 'csv', 'pdf'], 
       sizeLimit: 1024*1024*1 // 1MB 
      }, 
     multiple: true, 
     text: { 
       uploadButton: '<i class="icon-plus icon-white"></i>Select your upload file(s)' 
      }   
    })     

     .on('complete', function(event, id, fileName, responseJSON) { 
      alert("Success: " + responseJSON.success); 

      uploadedFileCounter++; 
      if (filesToUpload == uploadedFileCounter) 
      { 
       alert("DONE UPLOADING!"); 
      }   

    }).on('submitted', function(event, id, filename) { 
      filesToUpload++; 
      alert("submitted: " + filesToUpload); 
     } 
    }); 
});

您的代码中充斥着语法和其他错误。首先，您引用了代码中未定义的filesToUpload和uploadedFileCounter变量。其次，你的代码中有一个额外的右括号。

你的代码也有一些格式化问题。首先，你的代码不一致缩进。其次，你在混合放置大括号。

这里是你的原代码与我调整：

$(document).ready(function() { 

    var controlType = '@Model.ControlType', 
     surveyItemResultId = @Model.Results[0].SurveyItemResultId, 
     itemId = @Model.SurveyItemId, 
     instance = @Model.Results[0].SurveyInstanceID, 
     loopingCounter = 0, 
     filesToUpload = 0, 
     uploadedFileCounter = 0; 


    var fineuploader = $('#files-upload').fineUploader({ 
     request: { 
      endpoint: '@Url.Action("UploadFile", "Survey")', 
      customHeaders: { Accept: 'application/json' }, 
      params: { 
       surveyInstanceId: (function() { return instance; }), 
       surveyItemResultId: (function() { return surveyItemResultId; }), 
       itemId: (function() { return itemId; }), 
       loopingIndex: (function() { return loopingCounter++; }) 
      } 
     }, 
     validation: { 
      acceptFiles: ['image/*','application/pdf','text/csv'] , 
      allowedExtensions: ['jpeg', 'jpg', 'gif', 'png', 'csv', 'pdf'], 
      sizeLimit: 1024*1024*1 // 1MB 
     }, 
     multiple: true, 
     text: { 
      uploadButton: '<i class="icon-plus icon-white"></i>Select your upload file(s)' 
     } 
    }) 

     .on('complete', function(event, id, fileName, responseJSON) { 
      alert("Success: " + responseJSON.success); 

      uploadedFileCounter++; 
      if (filesToUpload == uploadedFileCounter) { 
       alert("DONE UPLOADING!"); 
      } 

     }).on('submitted', function(event, id, filename) { 
      filesToUpload++; 
      alert("submitted: " + filesToUpload); 
     }); 
});
