Internet explorer, Null!

What. Were. People. Thinking.

>new String(null).toString()
"null"

Ridiculous. Firefox doesn't do anything that stupid. Worse, it's broken my populate form from JSON code.

    populate_data: function(report) {
        for (key in report) {
            if (!$(key)) {
                continue;
            }

            $(key).value = report[key];
        }
    }
