如何在 juggernaut 中实现文本输入部分和发送按钮？

我已经遵循了 github 上的确切指南，并且正在执行最后一步：

“就是这样！现在转到 http://localhost:8080 观看剑圣的行动。”

将显示一个对话框。但是，我无法写任何文字。

我希望能够修复该页面以供实际聊天使用，而不仅仅是测试。

看来您需要遵循 Juggernaut 自述文件中标题为“基本用法”的行下的指南。

基本用法

Juggernaut 中的一切都是在通道的上下文中完成的。
JavaScript 客户端可以订阅您的服务器可以订阅的频道
发布到.首先，我们需要包含 Juggernaut 的 application.js
文件。默认情况下，Juggernaut 托管在端口 8080 上 - 所以我们可以
链接到那里的文件。

完成此操作后，您可以在控制器中实现上面提到的 Ruby 代码，该控制器从表单获取用户输入，然后调用类似 Juggernaut.publish("channel1", @user_data) 的内容，从而允许您的用户通过服务器向对方发送数据。
`

It looks like you need to follow the guide on the Juggernaut readme under that line titled Basic Usage.

Basic usage

Everything in Juggernaut is done within the context of a channel.
JavaScript clients can subscribe to a channel which your server can
publish to. First, we need to include Juggernaut's application.js
file. By default, Juggernaut is hosted on port 8080 - so we can just
link to the file there.
<script src="http://localhost:8080/application.js"
type="text/javascript" charset="utf-8">

We then need to instantiate the Juggernaut object and subscribe to the
channel. As you can see, subscribe takes two arguments, the channel
name and a callback.
<script type="text/javascript" charset="utf-8">
  var jug = new Juggernaut;
  jug.subscribe("channel1", function(data){
    console.log("Got data: " + data);
  });
</script>
That's it for the client side. Now, to publish to the channel we'll
write some Ruby:
require "juggernaut"
Juggernaut.publish("channel1", "Some data")
You should see the data we sent appear instantly in the open browser
window. As well as strings, we can even pass objects, like so:
Juggernaut.publish("channel1", {:some => "data"})
The publish method also takes an array of channels, in case you want
to send a message to multiple channels co-currently.
Juggernaut.publish(["channel1", "channel2"], ["foo", "bar"])
That's pretty much the gist of it, the two methods - publish and
subscribe. Couldn't be easier than that!

Once you have that done you can implement the Ruby code mentioned above inside a controller which takes the user input from a form and then calls something like Juggernaut.publish("channel1", @user_data) allowing your users to send data through the server to each other.
