Is there a way to give unique id numbers to a page?

Question

I get the data of all the movies on my home page. But I don't want to do this on the Admin.html page. On the admin page, when I click on the name of the movie, I want to go to the page related to that movie. For example, when I click on the movie "Schindler's List" which movieId is 3 (Admin.html?movieId=3), I want to go to a page with only Schindler's List movie information. It will show only Schindler List's img,score,name. How can I achieve this?

Admin.html
