ajax简单封装

 1 //eg:
 2 // var data ={
 3 //          id: id,
 4 //    typeName: mame,
 5 //     getcCity:city
 6 //    }
 7 //2.url:需要传到后台的url
 8 //3.callback :回调函数
 9 //+++++++++++++++++++++++Demo:+++++++++++++++++++++++++++++++++++
10 //var data ={
11 //    id: id,
12 //    typeName: name
13 //}
14 //var  url  = encodeURI("${pageContext.request.contextPath}/ajax/certificate/saveCertificateType");
15 //actionRequest(data,url,function(data){
16 //    if (data.successed) {
17 //        toNotification("提示！","操作成功！", "success");
18 //        //刷新表格
19 //        initnewAttributeTable();
20 //    }else {
21 //        toNotification("操作失败！", data.message, "error");
22 //    }
23 //});
24 //+++++++++++++++++++++++Demo:+++++++++++++++++++++++++++++++++++
