How to use the browser to scan the QR code to determine whether the app is installed on the phone.

If you need APP cooperation~~ you can search url schema or app schema related articles to learn more.
The idea is this:
The QR code is an intermediate page. It is recommended that this page be directly the download page.
Then the JS on this page tries to pull up the APP through the schema.
If installed, it will start. . It's stuck on this download page without installation. .
