Use basic authentication with jQuery and Ajax

Question

I am trying to create a basic authentication through the browser, but I can't really get there.

If this script won't be here the browser authentication will take over, but I want to tell the browser that the user is about to make the authentication.

The address should be something like:

http://username:[email protected]/

I have a form:

<form name="cookieform" id="login" method="post">
      <input type="text" name="username" id="username" class="text"/>
      <input type="password" name="password" id="password" class="text"/>
      <input type="submit" name="sub" value="Submit" class="page"/>
</form>

And a script:

var username = $("input#username").val();
var password = $("input#password").val();

function make_base_auth(user, password) {
  var tok = user + ':' + password;
  var hash = Base64.encode(tok);
  return "Basic " + hash;
}
$.ajax
  ({
    type: "GET",
    url: "index1.php",
    dataType: 'json',
    async: false,
    data: '{"username": "' + username + '", "password" : "' + password + '"}',
    success: function (){
    alert('Thanks for your comment!');
    }
});

Use jQuery's beforeSend callback to add an HTTP header with the authentication information:

beforeSend: function (xhr) {
    xhr.setRequestHeader ("Authorization", "Basic " + btoa(username + ":" + password));
},
