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