How to scan and identify the content of QR code on H5 page?

problem description: customers need to scan the QR code on the H5 page and be able to identify the content of the custom logic. Scan the code to identify the content of the QR code and fill in the form on the next page after querying the data from the background service.
I need to solve the problem of opening the H5 page in any browser or client to scan the code.

I tried to open the H5 page in Wechat and use the jssdk implementation of Wechat"s official account to call Wechat to scan the code. However, my H5 page was not sent and used when Wechat opened it. Is there any way to call Wechat to scan or call the mobile phone to scan the code directly on the page?

do you want to long press the H5 page to identify the QR code above

if H5 is running in its own APP, you can APP to scan the code, and then H5 calls it.
if H5 is running in a browser, it needs to scan the code on its own. For specific methods, please refer to http://blog.csdn.net/porcelai.

Scheme. Please see http://www.cnblogs.com/yisuow.
