I really have no idea what I'm doing wrong here. I can't get Datejs to properly parse "12:00 pm" however, it seems to work fine on other dates. Below is a clip from the Firefox debugger:

Try wrapping the code in an IIFE.

<!DOCTYPE html>
<html>
    <body>
        <input type=text id=d onkeyup="parsedate()">
        </input>
        <br>
        <span id=output></span>
        <script type="text/javascript" src="../../../static/js/date.js"></script>
        <script>
            ( function() {
                    parsedate = function() {
                        var input = document.getElementById('d').value;
                        var output = document.getElementById('output');
                        var d = Date.parse(input);
                        if (d !== null) {
                            output.innerHTML = d.toString();
                        } else {
                            output.innerHTML = "------"
                        }
                    }
                }());
        </script>
    </body>
</html>

The IIFE being

(function(){
    //code
}());

What I'm curious about is why FireFox behaves this way. I know they added security updates a few years back that prevent you from overwriting Date.prototype functions, but why is an IIFE capable of accessing this scope?

Download the latest version of Datejs from SVN not the version in the "download" section.
