Creating and deleting triggers by script


You can create or delete triggers programmatically as shown in the following sample code:

/**
 * Deletes all the triggers.
 *
 */
function deleteTriggers(){
  var triggers = ScriptApp.getProjectTriggers();

  triggers.forEach(function(trigger){

    try{
      ScriptApp.deleteTrigger(trigger);
    } catch(e) {
      throw e.message;
    };

    Utilities.sleep(1000);

  });

};

function createTrigger(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();

  // Create new trigger
  ScriptApp.newTrigger("sendEmail")
    .forSpreadsheet(ss).onFormSubmit().create();
};

Note

In the deleteTriggers function, the Utilities service's sleep method is used to pause the script temporarily for the specified milliseconds. Otherwise, you may experience the Too many service invocation… error.
