Listing 1.4
A HTML test page

We then copy our console session into a new file, shown in Listing 1.5, which
will serve as the test file. To log results we'll simply use
console.log
, which is
available in most modern browsers, and logs to the browser's JavaScript console.
Listing 1.5
strftime test.js
var date = new Date(2009, 11, 5);
console.log(date.strftime("%Y"));
console.log(date.strftime("%m"));
console.log(date.strftime("%d"));
console.log(date.strftime("%y"));
console.log(date.strftime("%F"));
We now have a reproducible test case. We can then attend to the failure:
"%y"
does not zero pad the number it returns. It turns out we simply forgot
to wrap the method call in a
zeroPad()
call. Listing 1.6 shows the updated
Date.formats.y
method.
Listing 1.6
Zero-pad year
Date.formats = {
// ...
y: function (date) {
return zeroPad(date.getYear() % 100);
}
// ...
};
