ajax简单封装

//eg:
// var data ={
//          id: id,
//    typeName: mame,
//     getcCity:city
//    }
//2.url:需要传到后台的url
//3.callback :回调函数
//+++++++++++++++++++++++Demo:+++++++++++++++++++++++++++++++++++
//var data ={
//    id: id,
//    typeName: name
//}
//var  url  = encodeURI("${pageContext.request.contextPath}/ajax/certificate/saveCertificateType");
//actionRequest(data,url,function(data){
//    if (data.successed) {
//        toNotification("提示！","操作成功！", "success");
//        //刷新表格
//        initnewAttributeTable();
//    }else {
//        toNotification("操作失败！", data.message, "error");
//    }
//});
//+++++++++++++++++++++++Demo:+++++++++++++++++++++++++++++++++++
