Cross origin requests are only supported for HTTP but it's not cross-domain

Question

I\'m using this code to make an AJAX request:

$(\"#userBarSignup\").click(function(){
    $.get(\"C:/xampp/htdocs/webname/resources/templates/signup.php\",
          


        

Answer 1

I've had luck starting chrome with the following switch:

--allow-file-access-from-files

On os x try (re-type the dashes if you copy paste):

open -a 'Google Chrome' --args -allow-file-access-from-files

On other *nix run (not tested)

 google-chrome  --allow-file-access-from-files

or on windows edit the properties of the chrome shortcut and add the switch, e.g.

 C:\ ... \Application\chrome.exe --allow-file-access-from-files

to the end of the "target" path

It works best this way. Make sure that both files are on the server. When calling the html page, make use of the web address like: http:://localhost/myhtmlfile.html, and not, C::///users/myhtmlfile.html. Make usre as well that the url passed to the json is a web address as denoted below:

$(function(){
                $('#typeahead').typeahead({
                    source: function(query, process){
                        $.ajax({
                            url: 'http://localhost:2222/bootstrap/source.php',
                            type: 'POST',
                            data: 'query=' +query,
                            dataType: 'JSON',
                            async: true,
                            success: function(data){
                                process(data);
                            }
                        });
                    }
                });
            });

I was getting the same error while trying to load simply HTML files that used JSON data to populate the page, so I used used node.js and express to solve the problem. If you do not have node installed, you need to install node first.

1. Install express npm install express

2. Create a server.js file in the root folder of your project, in my case one folder above the files I wanted to server

3. Put something like the following in the server.js file and read about this on the express gihub site:

   var express = require('express');
   var app = express();
   var path = require('path');
   
   // __dirname will use the current path from where you run this file 
   app.use(express.static(__dirname));
   app.use(express.static(path.join(__dirname, '/FOLDERTOHTMLFILESTOSERVER')));
   
   app.listen(8000);
   console.log('Listening on port 8000');
   

4. After you've saved server.js, you can run the server using:

node server.js

5. Go to http://localhost:8000/FILENAME and you should see the HTML file you were trying to load
