getEventType()

Returns the event type that the trigger fires on.

 {code
 var triggers = ScriptApp.getScriptTriggers();
 for(var i in triggers) {
   if(triggers[i].getTriggerSource() == ScriptApp.EventType.CLOCK) {
     // Some code here - other options are:
     // ScriptApp.EventType.ON_EDIT
     // ScriptApp.EventType.ON_FORM_SUBMIT
     // ScriptApp.EventType.ON_OPEN
   }
 }
 }

Return

EventType — the event type that this is a trigger for

getHandlerFunction()

Returns the function that will be called when the trigger fires.

 // create a trigger for the ScriptApp
 script.newTrigger("myFunction").forSpreadsheet("id of my spreadsheet").onEdit().create();
 Logger.log(ScriptApp.getScriptTriggers()[0].getHandlerFunction()); // logs "myFunction"
 

Return

String — the method name

getTriggerSource()

Returns the source of events that will cause the trigger to fire. For example, a spreadsheet onEdit trigger would return SPREADSHEETS, or a time based trigger would return CLOCK.

 var triggers = ScriptApp.getScriptTriggers();
 for(var i in triggers) {
   if(triggers[i].getTriggerSource() == ScriptApp.TriggerSource.CLOCK) {
     Logger.log(triggers[i].getUniqueId() + " source is clock");
   } else if (triggers[i].getTriggerSource() == ScriptApp.TriggerSource.SPREADSHEETS) {
     Logger.log(triggers[i].getUniqueId() + " source is spreadsheets");
   }
 }
 

Return

TriggerSource — the publisher this is a trigger for

getTriggerSourceId()

Returns the id specific to the source. For example, if the trigger source is a spreadsheet, this would be the id of the spreadsheet. For clock events this returns null.

Return

String — the id of the entity in the publisher that this is a trigger for

getUniqueId()

Returns a unique identifier that can be used to distinguish triggers from each other.

Return

String — the unique identifier of the trigger
