HTML/Javascript get variable on page load

Question

In some website pages, when i try to open the "View Source" with google chrome, and check the hidden values, I find out that the val is blank, but when i inspect the form, i can actually see the content of that hidden value,

for example, this site, when i try check the source i can't see the nid value, I think it has something to do with this function,

<script type="text/javascript">
    function upuid(a){
        $('input[name="nid"]').val(a)
    }
</script>

but I can't find where it is being called and what is the a parameter.

Thank you.

The view page source page shows you the exact text that was returned by the server. Inspect element actually shows you the fully rendered DOM tree.

The value is set from the client side. That's why you can't see it in the source. My guess the method get's called from the https://www.clixsense.com/uid.swf through ExternalInterface.call. The "a" is a string, and in this case it's a unique identifier.
