A handy function to take an object and fill an HTML form with those values. It would be nice to not use $.each() as it's slow, but this clean and easy.

fillForm.js

function fillForm(formSelector, data) {
    $.each(data, function (name, val) {
        var
            $el = $(formSelector + ' [name="' + name + '"]'),
            type = $el.attr('type');

        switch (type) {
            case 'checkbox':
                $el.attr('checked', 'checked');
                break;
            case 'radio':
                $el.filter('[value="' + val + '"]').attr('checked', 'checked');
                break;
            default:
                $el.val(val);
        }
    });
}
