JQuery, ajax, port number
ajax, java, jquery
Solution
Specifying port in ajax calls won't work due to Same origin policy (http://en.wikipedia.org/wiki/Same_origin_policy). Which means that URL must have the same domain and port as the server, where script's hosted.
Also, please note that this question was already asked, and is one of the first results when searching in google - Is it possible to specify a port in a ajax call
Problem
How to get a json from server `http://localhost:2323` if $.Ajax in jQuery doesn't work. The json is generated width java class: ``` public class Main { public static void main(String[] arr) { new Main().start(); } protected void start() { for (;;) { try { Socket remote = new ServerSocket(2323).accept();//port number BufferedReader in = new BufferedReader(new InputStreamReader( remote.getInputStream())); PrintWriter out = new PrintWriter(remote.getOutputStream()); String str = "."; while (!str.equals("")) str = in.readLine(); out.println("HTTP/1.0 200 OK"); out.println("Content-Type: text/html"); out.println("Server: Bot"); out.println(""); out.print("{\"a\":\"A\",\"b\":\"asdf\",\"c\":\"J\"}"); out.flush(); remote.close(); } catch (Exception e) { System.out.println("Error: " + e); } } } } ``` that outputs {"a":"A","b":"asdf","c":"J"}. And jquery script is ``` $(document).ready(function() { $.ajax({ type: 'POST', dataType: 'json', url: 'http://localhost:2323',//the problem is here async: false, data: {}, success: function(data) { alert(data.a+' '+data.b+' '+data.c); } }); }); ``` if url is `http://localhost`, then it works, if i append an :portnumber, it doesn't work. How to read from an url:portnumber? Thanks
