重新加载后如何将数据保留在页面中？

Question

I have a page which loads a login page, after the user logged in it will load some parts of another file into itself. The problem is that I want to know which button is pressed in the first page and have it in the login page. The first page loads login page using location.window and it refreshes the page. Is there a way to do this?

Answer 1

另外，您可以利用cookie / HTML5 localStorage来跟踪页面URL。

Answer 2

If you are using FORM then you can send the button information in hidden field, like

<input type="hidden" name="track" value="but1">

or if you are using GET method, you can send the info by query string, like

http://domain/login.php?track=but1
