问题描述

我想知道我怎么在asp.net mvc的回传后场清楚？就像现在，当出现验证错误的字段留填充任何一个用户将输入。这是好的但是，如果没有发生检验错误，我希望所有来清除字段和要显示的消息。

I am wondering how do I clear fields after a postback in asp.net mvc? Like right now when validation errors occur the fields stay populated with whatever a user would entered. This is fine however, when no validation errors occur I want the all the fields to clear and a message to display.

所以，现在我有成功的显示使用的ViewData，但不知道怎么去田里清除。

So right now I have the success displaying by using ViewData but not sure how to get the fields to clear.

推荐答案

听起来像是一个工作的的 PRG（后重定向获取）模式的，因为你不希望用户刷新页面，并再次提交。

Sounds like a job for the PRG (Post Redirect Get) pattern because you don't want the users to refresh the page and have it submit again.

要做到这一点，我会把消息或标志的TempData的，这样你可以检查，当你重定向回原来的网址，然后显示一个信息给用户。

To do this I would put a message or flag in your TempData so that you can inspect that when you redirect back to the original url to then display a message to the user.
