You need to give a name to your Schedule task.

你需要给你的计划任务命名。

So first here's how you schedule a task with node-schedule

首先，我们来看看如何用node-schedule安排一个任务

var schedule = require('node-schedule');
var date = new Date();
date.setMinutes(date.getMinutes() + 2);
schedule.scheduleJob('hereisthename', date, function(params)
{

  //Tasks to execute

}.bind(null, params));

It will schedule a task that going to be executed in two minutes with the name "hereisthename"

它会安排一个任务在两分钟内执行，名字是"hereisthename"

then if you want to cancel it

如果你想取消它

var scheduled = schedule.scheduledJobs;
if (scheduled['hereisthename'] != null)
   scheduled['hereisthename'].cancel();
