Socket.io socket.emit/socket.on 不工作

Question

I'm writing an app where i have multiple socket.io custom events, and all work fine, except this one:

socket.on("incomingImg", function(data) {
          var newimagesrc = data.image
          alert("new image");
         $("#messages").append(

                $("<img id='image' src='" + newimagesrc +"' >").text(
                     data.sender + ": [IMAGE]: " +
                    data.image           
                )

              );
         //$("#image").attr("src", newimagesrc);
        });

I've confirmed all the JQuery works, the only issue here is that on every client except the one I send this from, nothing happens. It may be worth noting that the client that initially sends the message is sending a different event; my server code looks like this:

socket.on("sendImg", function(data) {
    var imgdata = data.imageurl;
    var sendername = data.uname;
    console.log(imgdata);
    console.log(sendername);
    socket.emit('incomingImg', { image: imgdata, sender: sendername 
    });
  });

for some reason, when IncomingImg is emitted, only the client that sent sendImg receives it. Any help would be appreciated!

So as it turns out, one of the subtle details that Pineapple Joe mentioned in his comment was the problem, although it was actually my error - there was a typo in the event name on the server. Correcting that fixed the problem.
