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

因为“handleError”函数是在低版本的jquery 中的函数，所以解决方案是从低版本中的jquery 中找到这个函数

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

把这个函数加入ajaxfileupload.js中去，就不报错了。

jQuery.extend({

ajaxfileupload.js结合低版本jquery报异常:TypeError: jQuery.handleError is not a function

今天刚打个一个技术群，里面有人问标题上的问题，嘿，我恰好遇过，现在大家至少也在用jquery1.9以上的版本，ajaxfileupload的版本早就不更新了，大家可以下载看：地址这里，它例子里使用的Jquery是1.2的，好老呀。。。这个问题，我以前开发过程中遇过，网上说经测试（我是没测试），是版本1.4.2之前的版本才有handlerError方法，之后就不存在了，（你存在，我深深的脑海里。。。），为了能够继续使用ajaxfileupload上传我们的附件，只好将代码拷进我们的项目中的ajaxfileupload.js文件中，如下：
