Question

我有一个html客户端，那就是侦听来自JS服务器的事件。我可以确认在浏览器的客户端上我收到了事件，但是，事件没有显示在UI中。我想念什么？谢谢！

      var events = []
      const socket = io()
      socket.on('test', function(data) {
        console.log(data)
        events.push(data)
        trimmed = events.slice(Math.max(events.length - 30, 1))
        html = trimmed.reverse().map(function(data){
          return `<div class="media">
            <div class="media-left">
              <h3 class="media-heading">Test</h3>
            </div>
            <div class="media-body">
              <h4 class="media-heading">${data}</h4>
            </div>
          </div>`
        }).join('')
        $("#timeline")[0].innerHTML  = html
      }, false)
    </script>

无法查看从套接字到浏览器的事件
