ajaxfileupload.js上傳文件后調(diào)用error函數(shù)該如何處理

//上傳文件
$("#CompChange").click(function() {
 var params = $("#CompchangeTable").serialize();
 var json0={'video.slogan':$('#Cbasic_score').val(),'video.videoKind':$("#Cextra_score").val(),
	 'video.videoName':$("#name").val()};

 $.ajaxFileUpload({ 
	 type: "POST", 
	 url: "adminAction-upFile.action", 
	 data:json0,//要傳到后臺的參數(shù)，沒有可以不寫 
	 secureuri : false,//是否啟用安全提交，默認(rèn)為false 
	 fileElementId:['file1','file2'],//文件選擇框的id屬性 
	 dataType: 'json',//服務(wù)器返回的格式 
	 async : false, 
	 success: function(data){ 
 alert("成功");
	 }, 
	 error: function (data, status, e){ 
	 alert("失敗");
	 } 
	});
 });

	uploadHttpData : function(r, type) {
	var data = !type;
	data = type == "xml" || data ? r.responseXML : r.responseText;
	// If the type is "script", eval it in global context
	if (type == "script")
	jQuery.globalEval(data);
	// Get the JavaScript object, if JSON is used.
	if (type == "json"){	
	eval("data = " + data);
	}
	// evaluate scripts within html
	if (type == "html")
	jQuery("<p>").html(data).evalScripts();

	return data;
	}

uploadHttpData : function(r, type) {
	var data = !type;
	data = type == "xml" || data ? r.responseXML : r.responseText;
	// If the type is "script", eval it in global context
	if (type == "script")
	jQuery.globalEval(data);
	// Get the JavaScript object, if JSON is used.
	if (type == "json"){
	 ////////////以下為新增代碼/////////////// 
	 data = r.responseText; 
	 var start = data.indexOf(">"); 
	 if(start != -1) { 
	 var end = data.indexOf("<", start + 1); 
	 if(end != -1) { 
	 data = data.substring(start + 1, end); 
	 } 
	 } 
	 ///////////以上為新增代碼/////////////// 	
	eval("data = " + data);
	}
	// evaluate scripts within html
