/**

 * @param    date   [targetDate]   [判断目标时间]
 * @return   Boolean

        var curDate = new Date(targetDate),
            beginDate = new Date(beginDateStr),
            endDate = new Date(endDateStr);
        if (curDate >= beginDate && curDate <= endDate) {
            return true;
        }
