我想用ajax实现无刷新登录，想在登录完成后，在页面上显示当前登录的用户名，用户名在后台是通过session来存储的，但是每次登录成功后，直接取session为空，只能刷新页面后才能才能显示出来！求解决方案

应该不会出现这样的问题，或许你可以尝试在返回登录成功时一起加上你所需要的用户名等信息。
我就想问问你是怎么不刷新页面显示用户名的？
可以通过ajax的返回值里带有用户名，用js来更替更替HTML代码。
还有就是你在Ajax那里把用户名存储在SESSION里，你不刷新当然不能获取它的值。
后台登录验证成功后，将登录用户的用户名等信息保存到SESSION，并且在ajax返回值中也保存一份不就得了
你是不是没有把新值innerhtml到用户名位置？
描述的具体点楼主。
把你代码放上来看看，这个问题不一定是你刷新取不到值，因为登陆成功后是可以取到后台反馈回来的session值的，所以是你的代码的问题，你这么说，我们也不知道要从哪里着手，解决bug肯定是要看代码和反馈回来的bug信息才知道具体的问题在哪里
谢谢大家的支持，我已经解决问题了，谢谢！！
