Login Form For Http Basic Auth

I am running a Perl application named bitlfu.For login it is using something like Apache HTTP Basic Auth but not a form.I want to make form for the login with username and password field.
I have tried JavaScript and PHP with no results till now.

So I need help!

PS:
this kind of url works

http://user:password@host.com

I think a simple JavaScript like:

document.location='http://' + user + ':' + pass + '@mydomain.tld';

should do the work.

So basically, you have to create a form, with a user and pass field, then onsubmit, use the part of JavaScript given here:

<form method="post" onsubmit="javascript:document.location='http://' + $('login') + ':' + $('pass') + '@mydomain.tld';">
    <input type="text" name="login" id="login" />
    <input type="password" name="pass" id="pass" />
    <input type="submit" value="ok"/>
</form>

where $() is a document.getElementById or jquery or so. I used the $() function to make the code shorter. Here is an implementation, which does not work on every browser. Again, look throw jQuery for cross browser solution.

function $(_id) { return document.getElementById(_id); }

Otherwise, you can use php and redirect the user with a header location.

php way:

<?php

if (isset($_POST['login']) && isset($_POST['password'])) { header('Location: ' . urlencode($_POST['login']) . ':' . urlencode($_POST['password']) . '@domain.tld'); }
else
{
?>
<form method="post" onsubmit="javascript:document.location='http://' + $('login') + ':' + $('pass') + '@mydomain.tld';">
    <input type="text" name="login" id="login" />
    <input type="password" name="pass" id="pass" />
    <input type="submit" value="ok"/>
</form>

<?php
}
