如何调用节点。javascript服务器端方法?

I'm new to node.js but I know somewhat about socketstream web framework by using this I can easily call a server side node.js method from JavaScript. I don't know how to do this without using that framework. How can I call the node.js method from JavaScript?

我的新节点。但是我对socketstream web框架略知一二，通过使用这个我可以很容易地调用服务器端节点。js方法从JavaScript。如果不使用这个框架，我不知道该怎么做。如何调用节点。从JavaScript js方法?

The below code is using socketstream to call server side method. So I want to call the same server side method without using this framework.

下面的代码使用socketstream调用服务器端方法。所以我想不使用这个框架调用相同的服务器端方法。

ss.rpc('FileName.methodName',function(res){ 
    alert(res);         
});

I'd suggest use Socket.IO

我建议使用socket . io

Server-side code

服务器端代码

var io = require('socket.io').listen(80); // initiate socket.io server

io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' }); // Send data to client

  // wait for the event raised by the client
  socket.on('my other event', function (data) {  
    console.log(data);
  });
});

and client-side

和客户端

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io.connect('http://localhost'); // connec to server
  socket.on('news', function (data) { // listen to news event raised by the server
    console.log(data);
    socket.emit('my other event', { my: 'data' }); // raise an event on the server
  });
</script>

Alternatively, you can use a router function which calls some function on specific request from the client

或者，您可以使用路由器函数，该函数根据客户端的特定请求调用某些函数

var server = connect()
    .use(function (req, res, next) {
      var query;
      var url_parts = url.parse(req.url, true);
      query = url_parts.query;

      if (req.method == 'GET') {
        switch (url_parts.pathname) {
            case '/somepath':
            // do something
            call_some_fn()
            res.end();
            break;
          }
        }
    })
    .listen(8080);

And fire AJAX request using JQuery

并使用JQuery触发AJAX请求

$.ajax({
    type: 'get',
    url: '/somepath',
    success: function (data) {
        // use data
    }
})
