如何创建一条语句来检查google表单中的项是否有响应

function checkResponses() {
  var form = FormApp.getActiveForm();
  var items = form.getItems();
  
  for (var i = 0; i < items.length; i++) {
    var item = items[i];
    var response = form.getResponses();
    
    for (var j = 0; j < response.length; j++) {
      var itemResponse = response[j].getItemResponses();
      
      for (var k = 0; k < itemResponse.length; k++) {
        var responseItem = itemResponse[k].getItem();
        
        if (responseItem == item) {
          Logger.log(item.getTitle() + " has a response.");
          // You can perform any desired actions here
        }
      }
    }
  }
}
