bootstrap-datetimepicker添加支持显示农历节假日信息。

bootstrap-datetimepicker添加支持显示农历节假日信息。

最近再使用日期选择器发现没有显示农历的相关插件，于是网上找了一下有一些是独立的简单插件。最后干脆自己来修改bootstrap-datetimepicker

通过浏览器移动到日期位置右键审查元素查看源代码

bootstrap-datetimepicker添加支持显示农历节假日信息。

class 是day 或 today 所以打开bootstrap-datetimepicker.js 搜索 ‘today’

bootstrap-datetimepicker添加支持显示农历节假日信息。

这里附近应该就是渲染日历的地方，所以我们就在附近找。

html.push(‘’ + prevMonth.getUTCDate()+’‘);

这里这段应该就是渲染日历的地方,我们可以删掉试试,如果日期选择没日历就代表是这段。

那么其实我们只要在这里添加个P标签来显示农历和节假日就行了。

下面贴出计算节假日与万年历的代码

        } ,getJson:function(){
            return X
        }
    }
} )();

看不懂没关系会用就行，下面就使用例子

var c=new U(date);

//输出当前节假日信息或农历，如果是节假日会节假日如果没有就是农历
console.log(c.showInLunar);

//输出当前节假日信息或农历，如果是节假日会节假日如果没有就是农历，超过三个字会以 ..来显示 因为我们日历界面大小是有限制的所以超过的要省略
console.log(c.showInLunar);

//输出当前节假日信息或农历不会省略
console.log(c.lunarFestival);

//其他信息大家可以输出对象来查看
console.log(c);

下面开始为日历加上农历以及节假日信息吧。

html.push('<td class="' + classes.join(' ') + '">' + prevMonth.getUTCDate()+'</td>');

把原来渲染的代码改成下面这段代码

//获取当前时间详细信息包括节日信息
var c=new U(prevMonth);
var ct="农历&nbsp;"+c.lunarMonthInChinese+"月"+c.lunarDateInChinese+"&nbsp;" + c.solarFestival + c.lunarFestival;
html.push('<td class="' + classes.join(' ') + '">' + prevMonth.getUTCDate()+'<br><p  title='+ct+'>'+c.showInLunar + '</p></td>');

这样就可以显示农历了

我们还得修改下样式把大小调大点，还有给农历添加一些样式。

.table-condensed>tbody>tr>td{
    padding: 1px;
}
.datetimepicker table tr td.active p{
    color: #fff;
}
.datetimepicker  td,
.datetimepicker th {
    width: 50px;
}
.datetimepicker table tr td.old p,
.datetimepicker table tr td.new p{
    color: #999999;
}

最后还得修改下显示的天数

nextMonth.setUTCDate(nextMonth.getUTCDate() + 42);

修改成

nextMonth.setUTCDate(nextMonth.getUTCDate() + 35);

因为加上农历，时间选择器大小会变得很大所以我们要修改下渲染天数。

这样就大功告成了。
