文件上传ajaxfileupload请求

ajaxfileupload.js:101 Uncaught TypeError: jQuery.handleError is not a function 错误

1.handlerError只在jQuery-1.4.2之前的版本中存在，jQuery-1.4.2之后的版本中都没有这个函数了。
2.如果返回的dataType: “json”, 是json格式的，则还需要添加httpData方法。

将源码里面jQuery.extend函数修改为一下代码

jQuery.extend({createUploadIframe: function(id, uri){   //create frame            var frameId = 'jUploadFrame' + id;            var iframeHtml = '<iframe id="' +frameId+ '" name="' +frameId+ '" style="position:absolute; top:-9999px; left:-9999px"';if(window.ActiveXObject){                if(typeof uri== 'boolean'){iframeHtml += ' src="' + 'JavaScript:false' + '"';                }else if(typeof uri== 'string'){iframeHtml += ' src="' + uri + '"';                }}iframeHtml += ' />';jQuery(iframeHtml).appendTo(document.body);          return jQuery('#' + frameId).get(0);    },    createUploadForm: function(id, fileElementId, data){//create formvar formId = 'jUploadForm' + id;var fileId = 'jUploadFile' + id;var form = jQuery('<form  action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-dat   a"></form>');if(data){for(var i in data){jQuery('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form);}}var oldElement = jQuery('#' + fileElementId);var newElement = jQuery(oldElement).clone();jQuery(oldElement).attr('id', fileId);jQuery(oldElement).before(newElement);jQuery(oldElement).appendTo(form);//set attributesjQuery(form).css('position', 'absolute');jQuery(form).css('top', '-1200px');jQuery(form).css('left', '-1200px');jQuery(form).appendTo('body');return form;    },    ajaxFileUpload: function(s) {        // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout        s = jQuery.extend({}, jQuery.ajaxSettings, s);        var id = new Date().getTime()        var form = jQuery.createUploadForm(id, s.fileElementId, (typeof(s.data)=='undefined'?false:s.data));var io = jQuery.createUploadIframe(id, s.secureuri);var frameId = 'jUploadFrame' + id;var formId = 'jUploadForm' + id;        // Watch for a new set of requests        if ( s.global && ! jQuery.active++ ){jQuery.event.trigger( "ajaxStart" );}                    var requestDone = false;        // Create the request object        var xml = {}           if ( s.global )            jQuery.event.trigger("ajaxSend", [xml, s]);        // Wait for a response to come back        var uploadCallback = function(isTimeout){var io = document.getElementById(frameId);           try{if(io.contentWindow){ xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null;                 xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:i   o.contentWindow.document;}else if(io.contentDocument){ xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:n    ull;                 xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocumen   t:io.contentDocument.document;}            }catch(e){jQuery.handleError(s, xml, null, e);}            if ( xml || isTimeout == "timeout"){                requestDone = true;                var status;                try {                    status = isTimeout != "timeout" ?
