javascript - 监听socket.io中的多个事件

Question

我想向用户显示 socket.io 连接所处的状态。为此，我有一堆这些信息可以告诉用户。

#I can't use `*` because I have some customized events
socket.on 'my_command', =>
    set_status "connecting"

socket.on 'connecting', =>
    set_status "connecting"

socket.on 'disconnect', =>
    set_status "disconnect"

socket.on 'connect_failed', =>
    set_status "connect_failed"

有没有办法将所有这些压缩成更小的东西？像这样的东西:

socket.on 'connecting, disconnect, connect_failed', (name_of_event)=>
    set_status name_of_event

Answer 1

似乎socket.io不提供这样的短手绑定(bind)。您可以将其写在 for 循环中。

for event in ['connecting', 'disconnect', 'connect_failed']
  do (event) =>
    socket.on event, =>
      set_status event

# or
for event in 'connecting, disconnect, connect_failed'.split(/,\s*/)
  do (event) =>
    socket.on event, =>
      set_status event
