Question

到目前为止，我已经完成了这个功能，但它看起来很冗长，很丑陋。有没有办法动态生成月份或其他方法。

为了更好地理解，请看这个小提琴 http://jsfiddle.net/Yq3DW/67/

 function formatMonth(d) {
        switch (d) {
        case 0:
            return "Jan";
            break;
        case 1:
            return "Feb";
            break;
        case 2:
            return "Mar";
            break;
        case 3:
            return "Apr";
            break;
        case 4:
            return "May";
            break;
        case 5:
            return "Jun";
            break;
        case 6:
            return "jul";
            break;
        case 7:
            return "Aug";
            break;
        case 8:
            return "Sep";
            break;
        case 9:
            return "Oct";
            break;
        case 10:
            return "Nov";
            break;
        case 11:
            return "Dec";
        default:
            return "Jan"
        }
    }


function (d) {
return formatMonth(d);
}
