Google script - using template to build table

问题

Trying to build a report to be sent via email. My idea was to build the email using an HTML template, but I seem to be missing out on something... The email should contain a report which will include all entries with a specific month in ColB.

Here's a quick demo sheet

Here's my code

function MonthlyPulseCheck() {
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
  var pulsedate = new Date("02/02/2022"); 
  var pulsemonth = pulsedate.getMonth();
  var Pulsetable = buildmonthlypulse(pulsemonth);
  
  var emailtemplate  = HtmlService.createTemplateFromFile('Monthly pulse check');
    emailtemplate.OOOPULSE = Pulsetable;
  
  var emailbody = emailtemplate.evaluate();
  
  GmailApp.sendEmail('someone@gmail.com',( 'monthly pulse check for month ' + pulsemonth), '',
                     {htmlBody: emailbody.getContent(),
      name: 'test system', 
      from: 'alias@gmail.com', 
      replyTo: 'alias2@gmail.com',
})
}

function buildmonthlypulse(pulsemonth) {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
var Pulsearray = spreadsheet.getRange('A2:C').getValues();
var i = 0;
var counter = 1;
var imax = 15;//Pulsearray.length;
for (var i = 0; i < imax; i++) {
var arraydate = new Date(Pulsearray[i][1]);
var arraymonth = arraydate.getMonth();
//var pulseHTML = 0;
//var checkdate = new Date(arraydate);
if (arraymonth === pulsemonth) {
  if (counter === 1) {
  var pulseHTML = '<table style="float: right;"> <body> <tr> <td>&nbsp;TEXT2</td> <td>&nbsp;TEXT</td> <td><a href="ynet.co.il">&nbsp;NAME</a></td> </tr>'
  }
  var name =  spreadsheet.getRange(i+2, 1).getValue();
  var namelink = 'google.com';
  
  var pulseHTML = pulseHTML + '  <tr> <td>&nbsp;1</td> <td>&nbsp;2</td> <td><a href="youtube.com">&nbsp;3</a></td> </tr>';
  var counter = counter + 1;
  }
  
  }
  if (counter != 1) {
  var pulseHTML = pulseHTML + '</tbody> </table>';
  }
  return pulseHTML;
  }

Here's the HTML (used as a template)

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <?=OOOPULSE?>
  </body>
</html>

email is sent with just the digit 0 in the body. Can anyone make sense of this?

回答1:

I tried to replicate your code and found some issues:

In your function buildmonthlypulse(), you declared var pulseHTML multiple times inside the for loop which is not accessible to the return statement.
In your HTML file, you are using Printing scriptlets <?= ... ?> which is use for printing values with contextual escaping. The html elements in your var pulseHTML are recognized as string.

Solution:

Declare var pulseHTML = '' above the for loop statement (just like the commented one) and inside the for loop, remove var and retain pulseHTML. Example: pulseHTML = pulseHTML + '</tbody> </table>';
Instead of using Printing scriptlets "<?= ... ?>" use Force-printing scriptlets <?!= ... ?>. It is the same with Printing scriptlets but avoid contextual escaping.

Example Output:

Using Printing scriptlets

Using Force-printing scriptlets

Nitpick:
