How to remember Access Token on Redirect_URI page after VK authorization?

Question

JavaScript

Hello. The task is this: It is necessary to access the user's wall from a mobile application without using the contact SDK.
I send the user to the browser with the string "oauth.vk.com/authorize..." to allow access to his wall. In the Redirect_URI parameter, I specify my page on the Internet (so far this is a banal index.html without content). Next, the contact sends the user to my page containing a GET request with a parameter that contains the token and the user's Id.
Question: How to "tear out" these parameters (token and user id) at the moment the user goes to Redirect_URI from the address bar for their subsequent processing in JavaScript?
