How to send current url in javacript

How to send current url in javacript

I have contact form. Javascript with ajax calls another contact-form.php
file. Is any way to send with this javascript function current url to php
file? I want to see from witch page my clients have contacted with me.
In contact-form.php
$message .= "\n\Url: http://"
.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; obviously does not work.
My contact.js
jQuery(function ($) { var contact = { message: null, init: function () {
$('#contact-form input.contact, #contact-form a.contact').click(function
(e) { e.preventDefault();
// load the contact form using ajax
$.get( CI.base_url+"js/contact.php", function(data){
// create a modal dialog with the data
$(data).modal({
closeHTML: "<a href='#' title='Close'
class='modal-close'>x</a>",
position: ["15%",],
overlayId: 'contact-overlay',
containerId: 'contact-container',
onOpen: contact.open,
onShow: contact.show,
onClose: contact.close
});
});
});
},
open: function (dialog) {
// dynamically determine height
var h = 280;
if ($('#contact-subject').length) {
h += 26;
}
if ($('#contact-cc').length) {
h += 22;
}
var title = $('#contact-container .contact-title').html();
$('#contact-container .contact-title').html('Galvoju...');
dialog.overlay.fadeIn(200, function () {
dialog.container.fadeIn(200, function () {
dialog.data.fadeIn(200, function () {
$('#contact-container .contact-content').animate({
height: h
}, function () {
$('#contact-container .contact-title').html(title);
$('#contact-container form').fadeIn(200, function
() {
$('#contact-container #contact-name').focus();
$('#contact-container
.contact-cc').click(function () {
var cc = $('#contact-container #contact-cc');
cc.is(':checked') ? cc.attr('checked', '')
: cc.attr('checked', 'checked');
});
});
});
});
});
});
},
show: function (dialog) {
$('#contact-container .contact-send').click(function (e) {
e.preventDefault();
// validate form
if (contact.validate()) {
var msg = $('#contact-container .contact-message');
msg.fadeOut(function () {
msg.removeClass('contact-error').empty();
});
$('#contact-container .contact-title').html('Sending...');
$('#contact-container form').fadeOut(200);
