一、AJAX

(function ($) {
    //1.得到$.ajax的对象
    var _ajax = $.ajax;
    $.ajax = function (options) {
        //2.每次调用发送ajax请求的时候定义默认的error处理方法
        var fn = {
            error: function (XMLHttpRequest,textStatus,errorThrown) {
                toastr.error(XMLHttpRequest.responseText,‘错误消息‘,{ closeButton: true,timeOut: 0,positionClass: ‘toast-top-full-width‘ });
            },success: function (data,textStatus) { },beforeSend: function (XHR) { },complete: function (XHR,TS) { }
        }
        //3.扩展原生的$.ajax方法，返回最新的参数
        var _options = $.extend({},{
            error: function (XMLHttpRequest,errorThrown) {
                fn.error(XMLHttpRequest,errorThrown);
            },textStatus) {
                fn.success(data,textStatus);
            },beforeSend: function (XHR) {
                XHR.setRequestHeader(‘Authorization‘,‘BasicAuth ‘ + Ticket);
                fn.beforeSend(XHR);
            },TS) {
                fn.complete(XHR,TS);
            }
        },options);
        //4.将最新的参数传回ajax对象
        _ajax(_options);
    };
})(jQuery);
