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。
