如何在Google App脚本中求和范围列

Question

J    
1    
2    
3    

This is the code:

function sumsald () {
   var ss = SpreadsheetApp.getActiveSpreadsheet ();
   var s1 = ss.getSheetByName ("rendPendForm");
   var dataRange = s1.getDataRange ();
   var lastrow = dataRange.getLastRow ();
   var values = s1.getRange (2.10, lastrow, 1) .getValues ();
        var sum = 0;           
        for (var i = 0; i <values.length; i ++) {
            result = values [i] [10] + sum;
            Logger.log (result);
     }
     s1.getRange (i + 1, 10) .setValue (result);
  }

Result script = # NUM!
Logger.log = NaN

6 expected

Thanks, Luis.

Not sure if in the example the J is the column name or value on the first row. Anyway, to get values starting from first row in column J all the way to row on index lastrow :

var values = s1.getRange (1, 10, lastrow, 1) .getValues ();

In addition, when adding up the numbers its good to ignore non-number values. For example if you sum a string from a header row and a number from row below you get a concatenated string of the two in Javascript/GoogleScript, instead of an error or ignoring the string. This appends to the sum only if values[i][0] contains a number (otherwise adds 0 to the sum ie does nothing):

result += typeof values[i][0] == 'number' ? values[i][0] : 0;

Below full example:

function sumsald () {
  var ss = SpreadsheetApp.getActiveSpreadsheet ();
  var s1 = ss.getSheetByName ("rendPendForm");
  var dataRange = s1.getDataRange ();
  var lastrow = dataRange.getLastRow ();
  var values = s1.getRange (1, 10, lastrow, 1) .getValues ();
  var result = 0;
  for (var i = 0; i <values.length; i ++) {
    result += typeof values[i][0] == 'number' ? values[i][0] : 0;
    Logger.log (result);
  }
  s1.getRange (i + 1, 10) .setValue (result);
}
