It is possible to create a link in a mobile website that will open a QR code scanner on an iPhone or Android phone when the user clicks on it?
Specifically, I am building a site using jQuery Mobile and want to have a button that says "Scan QR Code." When the clicks on it, it will open whatever scanning app they have on their phone.
I found another similar question here, and it appears the answer is no.
This could help you:

Create a link like this one: http://qrdroid.com/scan?q=http://www.example.com/your_page?q={CODE}
The scanner will be launched. After the user scans a code, your webpage will be opened with the scanned code as parameter.
