树莓派Node-Red例5:中文日期时间的生成

 本例实现输出包含有中文的日期信息

 实际效果图

 通过"节点管理"来安装simpletime节点

 安装好后见图片上划红线部分,simpletime内部不需要设置和添加代码

 function节点的程序:

var payload=msg;
var dateStr=payload.mydate;
var tempstr=dateStr.split(" ");//用空格拆分字符串
var strobj=Object.assign({},tempstr);
var hzweekday,hzmonth;
var weekday=strobj[0];
var month=strobj[1];
var day=strobj[2];
var year=strobj[3];


switch(weekday){
    case "Mon":
        hzweekday="星期一";
        break;
    case "Tue":
        hzweekday="星期二";
        break;
    case "Wed":
        hzweekday="星期三";
        break;
    case "Thu":
        hzweekday="星期四";
        break;
    case "Fri":
        hzweekday="星期五";
        break;
    case "Sat":
        hzweekday="星期六";
        break;
    case "Sun":
        hzweekday="星期日";
        break;  
    default:
        break;
}
switch(month){
    case "Jan":
        hzmonth="1月";
        break;
    case "Feb":
        hzmonth="2月";
        break;
    case "Mar":
        hzmonth="3月";
        break;
    case "Apr":
        hzmonth="4月";
        break;
    case "May":
        hzmonth="5月";
        break;
    case "Jun":
        hzmonth="6月";
        break;
    case "Jul":
        hzmonth="7月";
        break; 
     case "Aug":
        hzmonth="8月";
        break;  
     case "Sept":
        hzmonth="9月";
        break; 
     case "Sep":
        hzmonth="9月";
        break; 
     case "Oct":
        hzmonth="10月";
        break;  
     case "Nov":
        hzmonth="11月";
        break;  
     case "Dec":
        hzmonth="12月";
        break;  
    default:
        break;
}
msg.payload=year+"年"+hzmonth+day+hzweekday+payload.mytimes;
return msg;
