从服务器返回数据到客户端javascript中发送的ajax请求

Question

• Node.js web server
• Request handler in web server

 app.get('/documents/:id.:format?', function(req, res) { **dataTobeSentToClientSideJavaScript** = processRequest (req); ... }) 

• ajax request from client side javascript

   var request = $.ajax({ url: "/documents/xxx", }); request.done(handleResponse); 

• I am able to receive the request on server side

What code should be written on server side so that I can populate the "handleRespone" object expected in my ajax request above with dataTobeSentToClientSideJavaScript created on server side?

Answer 1

You want to use methods exposed by the response object such as res.write, res.end or res.json

take a look at http://nodejs.org/api/http.html#http_class_http_serverresponse (Node.js API)

and since you're using Express - http://expressjs.com/api.html#res.status
