i'd like to ask some question about how to close a websocket client when offline/switched network.

when i try to close the socket for the 2 case in chrome, after i call websocket.close, i cannot recieve onclose event for a long time (around 60s), then i can recieve it finally.

after i check the readystate, i found that in the coming 60s, the state is 2(CLOSEING), not turned to 3(CLOSED).

so i'd like to know is there any steps i missed when i call websocket.close() in offline/switched network condition. while it runs well when the network is normal.
