JQuery. form Ajax no-refreshing upload error (jQuery. handleError is not a function) Solution

Today, when using ajaxfileupload, firebug reported a "jQuery. handleError is not a function" error. Because jQuery. form has never encountered this problem. I compared it with previous projects and found that jQuery is 1.10.2 in this project, but 1.4.2 was previously used. After du Niang, find the solution: jQuery. handleError is not a function. The error cause is:
HandlerError only exists in versions earlier than the jquery-1.4.2 and does not exist in Versions later than the jquery-1.4.2.

Therefore, this function is added in the jquery advanced version to solve the problem. This js Code segment can be added to jquer. js or ajaxfileupload. js.

; (function ($) {            jQuery.extend({                handleError: function (s, xhr, status, e) {                    if (s.error) {                        s.error.call(s.context || s, xhr, status, e);                    }                    if (s.global) {                        (s.context ? jQuery(s.context) : jQuery.event).trigger("ajaxError", [xhr, s, e]);                    }                },                httpData: function (xhr, type, s) {                    var ct = xhr.getResponseHeader("content-type"),            xml = type == "xml" || !type && ct && ct.indexOf("xml") >= 0,            data = xml ? xhr.responseXML : xhr.responseText;                    if (xml && data.documentElement.tagName == "parsererror")                        throw "parsererror";                    if (s && s.dataFilter)                        data = s.dataFilter(data, type);                    if (typeof data === "string") {                        if (type == "script")                            jQuery.globalEval(data);                        if (type == "json")                            data = window["eval"]("(" + data + ")");                    }                    return data;                }            });
