推荐答案

，您不知道答案吗?您应该将其视为学习一些东西的提示，而不仅仅是尝试获得问题的具体答案.你说什么 ?即使您不确定如何，您肯定会看到可以做到的事情? 他们是在谈论AJAX还是笨拙的ASP.NET AJAX库?如果您使用AJAX调用获取状态数据，则显然使用另一个AJAX调用保存选择. And you didn''t know the answer ? You should see that as a cue to learn some stuff, not just to try to get the specific answer to the question. What did you say ? Surely you see that you could do that, even if you''re not sure how ? Are they talking about AJAX, or the crappy ASP.NET AJAX library ? If you used an AJAX call to get the state data, it seems obvious to use another AJAX call to save the selection.
