设置后取消节点调度事件 [英] Cancel node-schedule event after it has been set

问题描述

我打算使用 node-schedule 为约会提醒设置推送通知，如下所示:

I am planning on using node-schedule to set up push notifications for appointment reminders as follows:

var schedule = require('node-schedule');
var date = req.body.date;   // Date for reminder from client request 
var j = schedule.scheduleJob(date, function(){
    // Send push notification
});

现在我知道你可以通过调用 cancel() 来取消事件:

Now I know you can cancel the event by calling cancel():

j.cancel()

但是，如果来自客户端的用户决定将约会更改为不同的日期，我该如何参考要取消的特定作业?

However, how can I refer to that specific job to cancel if the user from the client side decides to change the appointment to a different date?

预先感谢您的帮助！

推荐答案

为了检索特定作业，您可以使用唯一名称创建它，然后您可以通过该唯一名称检索它:

In order to retrieve a specific job, you could create it with a unique name and you can retrieve it later via that unique name:

var j = schedule.scheduleJob(unique_name, date, function() {
});
// later on
var my_job = schedule.scheduledJobs[unique_name];
my_job.cancel();
