我有一个费用表，我为每个相关用户复制到 Google Drive 文件夹中。工作表的每个副本都需要一个可安装的触发器，该触发器调用一个函数以在最后一行数据被编辑时插入额外的行。这些是使用 onEdit 事件触发的。手动创建（通过“ Edit Current Project's triggers”）时，可安装的触发器工作正常。

为了简化设置新用户的过程，我编写了触发器的创建脚本。虽然脚本创建了触发器并且它看起来与手动创建的完全相同，但它只有在我手动打开触发器、重新选择要触发的函数并重新保存时才有效。

我可以在运行创建脚本时确认我是所有者。

我看到的行为向我表明，我的脚本中的函数名称有问题，但对我来说一切都很好。我真的很感激这方面的一些帮助....

function createInsertRowsTrigger(){
  Logger.log('Id='+ss.getId());
createInstallableTrigger("onEditOfLastRow",ss.getId());
}

function createInstallableTrigger(funcName,ssId) {
      if(!isTrigger(funcName)) {
        ScriptApp.newTrigger(funcName).forSpreadsheet(ssId).onEdit().create();
      }
    }

function isTrigger(funcName){
       Logger.log('In isTrigger');
   var r=false;
   if(funcName){
     Logger.log('Function found');
     var allTriggers=ScriptApp.getProjectTriggers();
     for(var i=0;i<allTriggers.length;i++){
       if(funcName==allTriggers[i].getHandlerFunction()){
         r=true;
         Logger.log('trigger already exists');
         break;
       }
     }
   }
   return r;
 }
