How can I modify a trigger so that it emails upon edit, but not so quickly?

问题

I have a script that creates additional files upon submission of a Google Form. It also sets up a trigger for said new document, so that people are emailed when any edits are made to the document after its creation, e.g.

ScriptApp.newTrigger("sendEmailOnModification")
         .forSpreadsheet(SpreadsheetApp.openById(fileId))
         .onEdit()
         .create();

The logic all works, but... the trigger is extremely sensitive. Every time someone makes a single keystroke in the document, it fires. It doesn't make a lot of sense to repeatedly fire as someone writes a paragraph; it makes more sense to, say, fire 10 minutes after the last edit. (Or something. Anything that doesn't spam emails.)

Is there a way to modify the trigger so that it fires less often (I do not want a time-based trigger), or otherwise programmatically change how frequently Google Sheets saves?

As a last resort, I suppose I could create a hidden sheet that captures last modified time and a condition not to send an email if subsequent modifications are less than X minutes ago, but that's kind of clunky and not really appealing. Hoping I can do it entirely in Google Scripts instead.

回答1:

You could use the Properties Service to save a timestamp of the last time that the email was sent and compare it to the actual time of the current execution.

I'm not sure how you could implement this to suit your needs,but since you don't want a time based trigger, and you are already using onEdit(), you should be able to use onEdit(e) and e.oldValue to check if the change is worth the message.
