As shown in the picture, I use url to pass parameters to query data in the background, but every time the video game must be refreshed, the queried data will be refreshed. If it is not refreshed, the results of the previous query will still be displayed? What is the reason?

Do you have a more complete code? Do you return to the front page after querying in the background?
