在线日记系统设计

前段时间为了练手，自己设计了一个仿QQ邮箱日历 的在线日记系统

前台采用CSS+HTML+Javascript实现 

后端用的 是 MVC+DBMapper 实现

Vs2010+SQLServer2008开发的

核心部分如下：

用户登录

日历查看

农历查看（状态栏下方显示鼠标停放 的日期的农历）

日记编辑（点击日期编辑日记）

记事标注（有日记的日期做了淡黄色标注）

部分代码：

   ReFill: function () {//用最后一次填充的年月再次填充
        this.Fill(this.last_Year_Month);
    },
    Fill: function (s_d) {//参数必须是2015-9-1  格式  某个月的第一天 好确定 从哪个单元格开始绑定数字 到哪个单元格结束
        var table = document.getElementById(this.id);
        var ndate1 = this.getFormatDay(s_d);
        var todayDate = this.getFormatDay();
        var curday = 1;
        var maxday = this.monthDays[ndate1.Month];
        if (ndate1.Month === 1) {
            if ((ndate1.Year % 100 != 0 && ndate1.Year % 4 === 0) || ndate1.Year % 400 === 0) {
                maxday = 29;

            }

        }
        for (var i = 1; i < table.rows.length; i++)
            for (var j = 0; j < table.rows[i].cells.length; j++) {
                table.rows[i].cells[j].className = '';
                table.rows[i].cells[j].setAttribute('data', '');
                table.rows[i].cells[j].onmouseover = null;
                table.rows[i].cells[j].onmouseout = null;
                table.rows[i].cells[j].onclick = null;//清理上次填充时 加载的事件和属性 以免影响本次

                if ((i === 1) && (j < parseInt(ndate1.Week, 10))) {
                    table.rows[i].cells[j].innerHTML = ' ';

                }
                else {
                    if (curday > maxday) {
                        table.rows[i].cells[j].innerHTML = ' ';
                    }

                            table.rows[i].cells[j].className = 'today-cell';
                        }
