以编程方式删除定时触发器的麻烦 [英] Trouble programmatically deleting timed trigger

问题描述

我有一个测试脚本，我试图测试定时触发器。我需要能够以编程方式创建和删除触发器 - 根据文档可能这是可能的。然而，当我需要它的时候，我的触发器不会被删除：
$ b

I have a test script where I'm trying to test out timed triggers. I need to be able to create and delete triggers programmatically - which is possible according to the documentation. However, my trigger will not delete when I need it to:

function myFunction() {
  var db = ScriptDb.getMyDb();
  var user = Session.getActiveUser().getEmail();
  var triggerID = ScriptApp.newTrigger("timed").timeBased().everyMinutes(1).create().getUniqueId();

  var ob = {
    id: user,
    count: 1,
    trigger: triggerID
  }

  db.save(ob);
}

function timed(){
  var db = ScriptDb.getMyDb();
  var user = Session.getActiveUser().getEmail();
  var ob = db.query({id: user}).next();
  var count = ob.count;
  var triggerID = ob.trigger;

  if (count > 4){
    deleteTrigger(triggerID);
    db.remove(ob);

  } else {
    Logger.log(count + " " + Utilities.formatDate(new Date(), "GMT", "HH:mm:ss") + " TriggerID=" + triggerID);
    ob.count = count+1;
    db.save(ob);
  }
}

function deleteTrigger(triggerID){
  var allTriggers = ScriptApp.getProjectTriggers();

  for(var i=0; i < allTriggers.length; i++){
    if(allTriggers[i].getUniqueId() = triggerID){
      ScriptApp.deleteTrigger(allTriggers[i]);
      break;
    }
  }
}

推荐答案

为了测试相等性，您只需 == 而不是 = 在以下行中：

To test for equality, you just need == instead of = in the following line:

if (allTriggers[i].getUniqueId() = triggerID) {
