Firing the Facebook Conversion Pixel
I'm still pretty new to Javascript, but I was wondering what would be the best way to fire the Facebook conversion pixel (below) without actually loading a "confirmation"/"Thank You" page?
<script type="text/javascript">
var fb_param = {};
fb_param.pixel_id = 'XXXXXXXXXXX';
fb_param.value = '0.00';
fb_param.currency = 'USD';
(function(){
var fpw = document.createElement('script');
fpw.async = true;
fpw.src = '//connect.facebook.net/en_US/fp.js';
var ref = document.getElementsByTagName('script')[0];
ref.parentNode.insertBefore(fpw, ref);
})();
</script>
<noscript><img height="1" width="1" alt="" style="display:none"
src="https://www.facebook.com/offsite_event.php?id=XXXXXXXXXX&value=0&currency=USD" /></noscript>
Facebook says that we should plug this into our "Thank You pages" that visitors see after they convert (fill out a form, make a purchase, etc). However, some of our forms are popups or forms on sidebars next to content that we don't want readers to be directed away from by a confirmation page.
With Google Analytics, I can create an "invisible" pageview by firing _gaq.push(['_trackPageview']); code that can tell GA that it should count that invisible pageview as a goal completion.
Is there something similar to that that's general enough to tell my site to fire the FB pixel?

EDIT: I've updated my code as what I had mentioned previously did not work. Thanks to @Flambino to pointing out.
This is my revised answer using a pixel rather than a script to pass the conversion pixel. I reference the How to track a Google Adwords conversion onclick? SO post:
<head>
<script type="text/javascript">
function facebookConversionPixel(fb_pixel, fb_value){
var image = new Image(1,1);
image.src = "//www.facebook.com/offsite_event.php?id=" + fb_pixel + "&value=" + fb_value + "&currency=USD";
}
</script>
</head>
<body>
<a href="#" onclick="facebookConversionPixel(123456,0.00);">FBCONV</a>
</body>
