node.js中使用node-schedule实现定时任务实例

有的时候需要根据业务需要，晚上凌晨以后执行某些操作的时候，这个可能会有所帮助，我最近正在研究这个，欢迎共同探讨。

一、安装

npm install node-schedule

var schedule = require('node-schedule');
var date = new Date(2012, 11, 21, 5, 30, 0);

var j = schedule.scheduleJob(date, function(){
    console.log('The world is going to end today.');
});
取消预设计划

[code]
j.cancel();

var schedule = require('node-schedule');

var rule = new schedule.RecurrenceRule();
rule.minute = 42;
var j = schedule.scheduleJob(rule, function(){
    console.log('The answer to life, the universe, and everything!');
});

var rule = new schedule.RecurrenceRule();
rule.dayOfWeek = [0, new schedule.Range(4, 6)];
rule.hour = 17;
rule.minute = 0;

var j = schedule.scheduleJob(rule, function(){
    console.log('Today is recognized by Rebecca Black!');
});

五、每秒执行

　　var rule = new schedule.RecurrenceRule();

　　var times = [];
　　for(var i=1; i<60; i++){
　　　　times.push(i);
　　}
　　rule.second = times;
　　var c=0;
　　var j = schedule.scheduleJob(rule, function(){
     　　 c++;
      　　console.log(c);
　　});
