As others have suggested, you can set the username and password directly in the Ajax call:

$.ajax({
  username: username,
  password: password,
  // ... other parameters.
});

OR use the headers property if you would rather not store your credentials in plain text:

$.ajax({
  headers: {"Authorization": "Basic xxxx"},
  // ... other parameters.
});

Whichever way you send it, the server has to be very polite. For Apache, your .htaccess file should look something like this:

    AuthUserFile /path/to/.htpasswd
    AuthType Basic
    AuthName "Whatever"
    Require valid-user


Header always set Access-Control-Allow-Headers Authorization
Header always set Access-Control-Allow-Credentials true

SetEnvIf Origin "^(.*?)$" origin_is=$0
Header always set Access-Control-Allow-Origin %{origin_is}e env=origin_is

Explanation:

For some cross domain requests, the browser sends a preflight OPTIONS request that is missing your authentication headers. Wrap your authentication directives inside the LimitExcept tag to respond properly to the preflight.

Then send a few headers to tell the browser that it is allowed to authenticate, and the Access-Control-Allow-Origin to grant permission for the cross-site request.

In some cases, the * wildcard doesn't work as a value for Access-Control-Allow-Origin: You need to return the exact domain of the callee. Use SetEnvIf to capture this value.
