项目中用到了jQuery的ajaxFileUpload插件，提示错误“jQuery.handleError is not a function”，但该插件很早之前就不再更新了，而其中handlerError函数只存在于jquery-1.4.2版本，因此只需要把1.4.2中的函数复制到ajaxFileUpload.js中，即可解决本问题。

handleError: function( s, xhr, status, e ) {
       	// If a local callback was specified, fire it    	if ( s.error ) {
       		s.error.call( s.context || s, xhr, status, e );    	}    	// Fire the global callback    	if ( s.global ) {
       		(s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );    	}	}

完整ajaxFileUpload.js内容如下：

jQuery.extend({
       createUploadIframe: function(id, uri)	{
   			//create frame            var frameId = 'jUploadFrame' + id;            var iframeHtml = '&lt;/form&gt;');			if(data)		{<div></div>   			for(var i in data)			{<div></div>   				jQuery('&lt;input type="hidden" name="' + i + '" value="' + data[i] + '" /&gt;').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 attributes		jQuery(form).css('position', 'absolute');		jQuery(form).css('top', '-1200px');		jQuery(form).css('left', '-1200px');		jQuery(form).appendTo('body');				return form;    },    ajaxFileUpload: function(s) {<div></div>           // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout		        s = jQuery.extend({<div></div>   }, 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 &amp;&amp; ! jQuery.active++ )		{<div></div>   			jQuery.event.trigger( "ajaxStart" );		}                    var requestDone = false;        // Create the request object        var xml = {<div></div>   };         if ( s.global )            jQuery.event.trigger("ajaxSend", [xml, s]);        // Wait for a response to come back        var uploadCallback = function(isTimeout)		{<div></div>   						var io = document.getElementById(frameId);            try 			{<div></div>   								if(io.contentWindow)				{<div></div>   					 xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null;                	 xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:io.contentWindow.document;					 				}else if(io.contentDocument){<div></div>   					 xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:null;                	xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocument:io.contentDocument.document;				}						            }catch(e){<div></div>   				jQuery.handleError(s, xml, null, e);			}            if ( xml || isTimeout == "timeout") 			{<div></div>   				                requestDone = true;                var status;                try {<div></div>                       status = isTimeout != "timeout" ?
