Error loading XMLHttpRequest on LocalHost

Below is the code I am working on:

<script type="text/javascript>
   $(".link").click(function(){
   var id = this.id;

   if(id == 'b1'){
      $( "#content" ).load( "test.html", function(){
      alert('Successfully loaded!');
   });
   }      
   });
</script>

All my files are located on localhost as I am using it for educational purposes.
However, upon clicking the B1 button, Google Chrome displays the following error message:

Error Message:

OPTIONS file:///E:/mypath/folder/page.html No 'Access-Control-Allow-Origin'   
header is present on the requested resource. Origin 'null' is therefore not allowed access.

Answer №1

When working on your project locally, ensure that you access your page using the http protocol instead of the file protocol.

To maintain same origin security, consider adding // before the link like this:

$( "#conteudo" ).load( "//teste.html", function(){

If you need a local virtual machine webserver, you can find one with Virtual Box at:

Answer №2

When utilizing Chrome, keep in mind that it only supports XMLHttpRequests via http(s). To ensure compatibility, opt for http://localhost rather than file://localhost

Answer №3

To launch a web server using Python, simply execute the following command:

python -m SimpleHTTPServer

Running this command in the directory where your web files are stored will start a web server with ease.
