设置节点计划事件后将其取消 [英] Cancel node-schedule event after it has been set

问题描述

我计划使用 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，我知道您可以通过调用cancel（）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其他日期，我该如何取消该特定工作呢？

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?

请提前感谢您

推荐答案

要检索特定作业，可以使用唯一名称创建该作业，以后可以通过以下方式进行检索唯一的名称：

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();
