Wkhtmltopdf: show content on footer, e.g. page number

I expected this command to show the 1/1generated PDF in the boot file, but ... no idea?

wkhtmltopdf --footer-center [page]/[topage] www.google.com /tmp/foobar.pdf

Version: 0.12.2.4 on Linux

I think this problem may be caused by version 0.12.2.4, otherwise this command --footer-center [page]/[topage]will do your job.

another example, I checked what substitutePdfVariables()is called in bodyload.

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <script>
        function substitutePdfVariables() {

            function getParameterByName(name) {
                var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
                return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
            }

            function substitute(name) {
                var value = getParameterByName(name);
                var elements = document.getElementsByClassName(name);

                for (var i = 0; elements && i < elements.length; i++) {
                    elements[i].textContent = value;
                }
            }

            ['frompage', 'topage', 'page', 'webpage', 'section', 'subsection', 'subsubsection']
                .forEach(function(param) {
                    substitute(param);
                });
        }
    </script>
</head>
<body onload="substitutePdfVariables()">
    <p>Page <span class="page"></span> of <span class="topage"></span></p>
</body>
</html>

Here Documents you can find out more variables about the header and footer.
