With static works, but i want without static, so i can access to the controls in the aspx and validate the page.

我该怎么办呢？

推荐答案

您不能做这只是一个JavaScript调用，你需要回传，如果你想访问控制的页面上。该页面不知道什么是在文本框例如，除非您发送数据，这些数据的JavaScript调用不会做，而是一种形式或AJAX提交的意志。

You can't do this with just a javascript call, you need to postback if you want access to the controls on the page. The page doesn't know what's in the textboxes for example unless you send that data, which a javascript call won't do, but a form or AJAX submit will.

我建议一个JavaScript验证库，像这样。只是一定要还验证服务器上，一旦你提交检查禁用了JavaScript（或恶意行为试图绕过您的验证......）谁的用户。

I'd suggest a javascript validation library, something like this. Just be sure to also validate on the server once you've submitted to check for users who have javascript disabled (or are maliciously trying to bypass your validation...).
