从 Google Apps 脚本中的表格数据追加新幻灯片

Question

我已经设置了一个 Google Apps 脚本来生成新的 templated slides from data contained in a spreadsheet。该数据将定期更新。我计划设置一个项目触发器以定期生成新幻灯片。

现在，我通过简单地删除以前生成的幻灯片（参见下面的代码示例）来避免在触发更新期间复制幻灯片的问题，但我更愿意简单地附加新幻灯片而不是删除和重新生成（以保留对以前生成的幻灯片）。

更有经验的 Javascript 开发人员对这个任性的 R 编码器有何提示和技巧来解决这个问题？

function myFunction() {
  var dataSpreadsheetUrl = "https://docs.google.com/spreadsheets/d/1RjA4BJ4IKyjlh_l6vNaC7Q8wgUet1eNBo4_KJiF1pbQ/edit";
  var ss = SpreadsheetApp.openByUrl(dataSpreadsheetUrl);
  var deck = SlidesApp.getActivePresentation();
  var sheet = ss.getSheetByName('test');
  var values = sheet.getRange(2, 1, sheet.getLastRow(), sheet.getLastColumn()).getValues();
  var slides = deck.getSlides();
  var templateSlide = slides[1];
  var presLength = slides.length;
  
  // remove previously generated slides
  // TODO: figure out how to append rather than delete and regenerate
  for (var i = 2; i < slides.length; i++){
    slides[i].remove()
  }
  
  values.forEach(function(page){
  if(page[0]){ 
    
   templateSlide.duplicate();
   slides = deck.getSlides();
   newSlide = slides[2];
    
   var shapes = (newSlide.getShapes());
     shapes.forEach(function(shape){
       shape.getText().replaceAllText('{{name}}',page[0]);
       shape.getText().replaceAllText('{{value1}}',page[1]);
       shape.getText().replaceAllText('{{value2}}',page[2]);
       shape.getText().replaceAllText('{{value3}}',page[3]);
       shape.getText().replaceAllText('{{value4}}',page[4]);
       shape.getText().replaceAllText('{{value5}}',page[5]);
       shape.getText().replaceAllText('{{value6}}',page[6]);
       shape.getText().replaceAllText('{{value7}}',page[7]);
       shape.getText().replaceAllText('{{value8}}',page[8]);
       shape.getText().replaceAllText('{{value9}}',page[9]);
       shape.getText().replaceAllText('{{value10}}',page[10]);
    }); 
   presLength = slides.length; 
   newSlide.move(presLength); 
  }
  }); 
}

通过检查演示文稿长度来更新起始行来解决这个问题！

function myFunction() {
  var dataSpreadsheetUrl = "https://docs.google.com/spreadsheets/d/1RjA4BJ4IKyjlh_l6vNaC7Q8wgUet1eNBo4_KJiF1pbQ/edit";
  var ss = SpreadsheetApp.openByUrl(dataSpreadsheetUrl);
  var deck = SlidesApp.getActivePresentation();
  var sheet = ss.getSheetByName('test');
  var slides = deck.getSlides();
  var templateSlide = slides[1];
  var presLength = slides.length;

  // new data update //
  var rowLength = sheet.getLastRow();
  var startRow = 2;
  // update startRow when not initial run
  if(presLength != 2){
    startRow = presLength;
  }
  // save newly generated data range
  var values = sheet.getRange(startRow, 1, sheet.getLastRow(), sheet.getLastColumn()).getValues();
  
  values.forEach(function(page){
  if(page[0]){ 
    
   templateSlide.duplicate();
   slides = deck.getSlides();
   newSlide = slides[2];
    
   var shapes = (newSlide.getShapes());
     shapes.forEach(function(shape){
       shape.getText().replaceAllText('{{name}}',page[0]);
       shape.getText().replaceAllText('{{value1}}',page[1]);
       shape.getText().replaceAllText('{{value2}}',page[2]);
       shape.getText().replaceAllText('{{value3}}',page[3]);
       shape.getText().replaceAllText('{{value4}}',page[4]);
       shape.getText().replaceAllText('{{value5}}',page[5]);
       shape.getText().replaceAllText('{{value6}}',page[6]);
       shape.getText().replaceAllText('{{value7}}',page[7]);
       shape.getText().replaceAllText('{{value8}}',page[8]);
       shape.getText().replaceAllText('{{value9}}',page[9]);
       shape.getText().replaceAllText('{{value10}}',page[10]);
    }); 
   presLength = slides.length; 
   newSlide.move(presLength); 
  }
  }); 
}
