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, textStatus, errorThrown) { ???????????????fn.error(XMLHttpRequest, textStatus, errorThrown); ???????????}, ???????????success: function (data, textStatus) { ???????????????fn.success(data, textStatus); ???????????}, ???????????beforeSend: function (XHR) { ???????????????XHR.setRequestHeader(‘Authorization‘, ‘BasicAuth ‘ + Ticket); ???????????????fn.beforeSend(XHR); ???????????}, ???????????complete: function (XHR, TS) { ???????????????fn.complete(XHR, TS); ???????????} ???????}, options); ???????//4.将最新的参数传回ajax对象 ???????_ajax(_options); ???};})(jQuery);
