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

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

$("#userBarSignup").click(function(){
    $.get("C:/xampp/htdocs/webname/resources/templates/signup.php",
        {/*params*/},
        function(response){
            $("#signup").html("TEST");
            $("#signup").html(response);
        },
        "html");

But from the Google Chrome JavaScript console I keep receiving this error:

XMLHttpRequest cannot load
file:///C:/xampp/htdocs/webname/resources/templates/signup.php. Cross
origin requests are only supported for HTTP.

The problem is that the signup.php file is hosted on my local web server that's where all the website is run from so it's not cross-domain.

How can I solve this problem?

Answer

You need to actually run a webserver, and make the get request to a URI on that server, rather than making the get request to a file; e.g. change the line:

    $.get("C:/xampp/htdocs/webname/resources/templates/signup.php",

to read something like:

    $.get("http://localhost/resources/templates/signup.php",

and the initial request page needs to be made over http as well.
