移动HTML 5：检测互联网连接可用性

Question

Just that, is there a way to detect if the internet connection is available on a mobile device?. Can I do some kind of ping to server using websockets? Will websockets help me with that?

I'm kinda desperate, because I thought websockets had a ping function on the client-side box, but not I try to find something about that, and there's nothing like that, besides websockets seem only to respond to connections and data transmission events.

Answer 1

You can try to ping a server, as you already considered. This question contains a working example which uses the native Image object to do this.

I hope this helps.
