Code for determining the networking type and connection status through JS China's mobile network environment is complex. In order to provide users with a better access experience, developers hope to understand the user's current networking method and then give users a request result that meets the current network environment. W3C provides a method to obtain the current network status navigator.

This article mainly introduces the implementation code for determining the network type and connection status through JS. For more information, see the complicated mobile network environment in China, the developer wants to know the user's current networking method, and then gives the user a request result that conforms to the current network environment. W3C provides a method to obtain the current network
