在socket.io中,您可以向除发件人之外的所有客户端发送消息,例如:

socket.broadcast.emit('user connected');

但在rails/actioncable中,怎么做？

class BoardChannel < ApplicationCable::Channel
   def subscribed
     stream_from "board:#{params[:board]}"
   end

   def speak
     # client will call @perform('speak')
     result = do_something()
     # how to send 'result' to all client except sender?
   end
 end

我使用jquery来控制chrome中的SVG文件,

$('svg #lotsofimage').append("<image xlink:href='" + conf[thing].base + "' width= '" + conf[thing].width + "px' height= '" + conf[thing].height + "px' x='" + thing_x + "pt' y='" + thing_y + "pt' ></image>");

但我打开开发工具,它显示如下:

<img xlink:href="xxxx" width="xxxx">
<image></image>was instead of <img />

怎么处理？

在 socket.io 中，您可以回复消息给发件人，例如：

 socket.on('records', function(sheet_id){
    records = Record.all
    //send message to sender
    socket.emit('records', records);
  });

但在导轨中：

 class BoardChannel < ApplicationCable::Channel
   def subscribed
     stream_from "board:#{params[:board]}"
   end

   def speak
     # client will call @perform('speak')
     result = do_something()
     # how to send 'result' to sender?
   end
 end
