如何使用 Google App Scripts 在学生考勤表的最后一行添加彩色条纹？

Question

作为学生考勤系统的一部分，我想使用 App 脚本为课堂的每一行添加一条彩色条纹以供考勤。 我的 Google 表格列是：(i) 日期、(ii) 电子邮件、(iii) 纬度、(iv) 经度和 (v) 主题代码。 尝试了很多方法，但没有找到解决方案。

  var sss = SpreadsheetApp.getActiveSpreadsheet();
  var ssID = sss.getId();
  var sheetName = sss.getName(); 
  var sheet = sss.getSheetByName("TempDataSet");
  var sheet1 = sss.insertSheet('TempDataSet_temp');
  sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
  sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_FORMAT, false);

  
  var shID = sheet1.getSheetId().toString();
  sheet1.getRange(2, 1, sheet.getLastRow() -1, sheet.getLastColumn()).sort({column: 1, ascending: false}); 
  var columns_delete = [7,2]; //[7,5,4,2];
  columns_delete.forEach(col=>sheet1.deleteColumn(col));

  //const sss = SpreadsheetApp.getActiveSpreadsheet();
  //const sheet = sss.getSheetByName("TempDataSet");
  
  const subs = sheet.getRange('F2:F'+sheet.getLastRow()).getValues().flat();
  const usubs = subs.filter((value, index, self)=>self.indexOf(value) === index);
  const dts = sheet.getRange('A2:A'+sheet.getLastRow()).getDisplayValues().flat();
  const udts = dts.filter((value, index, self)=>self.indexOf(value) === index);
  
  if(usubs.length>1){
    subs.forEach((s,i)=>{
    if(i>1){
      if(subs[i]!=subs[i-1]){
        sheet.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }
  else if (udts.length>1){
    dts.forEach((d,i)=>{
    if(i>1){
      if(dts[i]!=dts[i-1]){
        sheet.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }
 
  var from = Session.getActiveUser().getEmail();
  var subject = 'Batch Attendance Record for Your Reference';
  var body = 'Dear Student,'+ '\n\n' + 'Greetings! Please find the batch attendance record attached. Stay safe and blessed.' + '\n\n' + 'Thank you.';
  
  var requestData = {"method": "GET", "headers":{"Authorization":"Bearer "+ScriptApp.getOAuthToken()}};  
  var url = "https://docs.google.com/spreadsheets/d/"+ ssID + "/export?format=xlsx&id="+ssID+"&gid="+shID;

  var result = UrlFetchApp.fetch(url , requestData);  
  var contents = result.getContent();
  sss.deleteSheet(sss.getSheetByName('TempDataSet_temp'));   
  
  var sheet2 = sss.getSheetByName('StudentList');  
  var data = sheet2.getLastRow();
  var students = [];
  var students = sheet2.getRange(2, 6, data).getValues(); 
  //MailApp.sendEmail(students.toString(), subject ,body, {attachments:[{fileName:sheetName+".xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]});
    
  for (var i=0; i<students.length; i++){ // you are looping through rows and selecting the 1st and only column index
    if (students[i][0] !== ''){           
      MailApp.sendEmail(students[i][0].toString(), subject ,body, {attachments:[{fileName:sheetName+".xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]}); 
      //MailApp.sendEmail(students[i][0].toString(), subject ,body, {from: from, attachments:[{fileName:"YourAttendaceRecord.xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]});
    } 
  }

Answer 1

解释：

根据您的问题，我了解以下步骤：

1. 检查E列中是否至少有两个独特的主题。 一种方法是找到唯一的主题列表。 如果该列表的长度为2或更多，则意味着您有不同的主题。 在这种情况下， if语句的第一个块的计算结果为true并且您在更改主题之前的行中添加一条黄线。

2. 如果您只有一个主题，即主题唯一列表的长度为1 ，则if语句的第一个块将评估为false 。 在这种情况下，脚本将检查A列是否有2或更多唯一日期。 如果是，则将执行if语句的第二个块，并且脚本将在更改日期之前的行中添加一条黄线。 否则，它不会做任何事情。

解决方案：

您可以将color()作为独立脚本执行。 我建议您将此函数保存在一个新的.gs文件中，然后只需在当前脚本中调用它。 即，将color()放在您提供的代码片段中您想要的任何位置。

function color() {
  const sss = SpreadsheetApp.getActiveSpreadsheet();
  const sheet = sss.getSheetByName("TempDataSet");
  
  const subs = sheet.getRange('E2:E'+sheet.getLastRow()).getValues().flat();
  const usubs = subs.filter((value, index, self)=>self.indexOf(value) === index);
  const dts = sheet.getRange('A2:A'+sheet.getLastRow()).getDisplayValues().flat();
  const udts = dts.filter((value, index, self)=>self.indexOf(value) === index);
  
  if(usubs.length>1){
    subs.forEach((s,i)=>{
    if(i>1){
      if(subs[i]!=subs[i-1]){
        sheet.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }
  else if (udts.length>1){
    dts.forEach((d,i)=>{
    if(i>1){
      if(dts[i]!=dts[i-1]){
        sheet.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }

  }

完整解决方案：

function sendEmails(){  

  
  var sss = SpreadsheetApp.getActiveSpreadsheet();
  var ssID = sss.getId();
  var sheetName = sss.getName(); 
  var sheet = sss.getSheetByName("TempDataSet");
  var sheet1 = sss.insertSheet('TempDataSet_temp');
  sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
  sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_FORMAT, false);

  var shID = sheet1.getSheetId().toString();
  sheet1.getRange(2, 1, sheet.getLastRow() -1, sheet.getLastColumn()).sort({column: 1, ascending: true}); 
  var columns_delete = [7,2]; //[7,5,4,2];
  columns_delete.forEach(col=>sheet1.deleteColumn(col));
  SpreadsheetApp.flush();
  
 const subs = sheet1.getRange('E2:E'+sheet1.getLastRow()).getValues().flat();
  const usubs = subs.filter((value, index, self)=>self.indexOf(value) === index);
  const dts = sheet1.getRange('A2:A'+sheet1.getLastRow()).getDisplayValues().flat();
  const udts = dts.filter((value, index, self)=>self.indexOf(value) === index);
  
  if(usubs.length>1){
    subs.forEach((s,i)=>{
    if(i>1){
      if(subs[i]!=subs[i-1]){
        sheet1.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }
  else if (udts.length>1){
    dts.forEach((d,i)=>{
    if(i>1){
      if(dts[i]!=dts[i-1]){
        sheet1.getRange(i+1,1,1,5).setBackground('yellow');
      }}});
  }
  SpreadsheetApp.flush();
  var from = Session.getActiveUser().getEmail();
  var subject = 'Batch Attendance Record for Your Reference';
  var body = 'Dear Student,'+ '\n\n' + 'Greetings! Please find the batch attendance record attached. Stay safe and blessed.' + '\n\n' + 'Thank you.';
  
  var requestData = {"method": "GET", "headers":{"Authorization":"Bearer "+ScriptApp.getOAuthToken()}};  
  var url = "https://docs.google.com/spreadsheets/d/"+ ssID + "/export?format=xlsx&id="+ssID+"&gid="+shID;

  var result = UrlFetchApp.fetch(url , requestData);  
  var contents = result.getContent();
  sss.deleteSheet(sss.getSheetByName('TempDataSet_temp'));   
  
  var sheet2 = sss.getSheetByName('StudentList');  
  var data = sheet2.getLastRow();
  var students = [];
  var students = sheet2.getRange(2, 6, data).getValues(); 
  //MailApp.sendEmail(students.toString(), subject ,body, {attachments:[{fileName:sheetName+".xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]});
    
  for (var i=0; i<students.length; i++){ // you are looping through rows and selecting the 1st and only column index
    if (students[i][0] !== ''){           
      MailApp.sendEmail(students[i][0].toString(), subject ,body, {attachments:[{fileName:sheetName+".xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]}); 
      //MailApp.sendEmail(students[i][0].toString(), subject ,body, {from: from, attachments:[{fileName:"YourAttendaceRecord.xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]});
    } 
  }
