如何使用变量引用 Google 表格脚本中的特定行？

Question

In my script, I need to refer to a specific row by using the number in a variable. For example, if the variable "rownumber" is 21, I want to have this code line:

var final_row = target_sheet.getRange('21:21');

Answer 1

You can use the getRange(row, column, numRows, numColumns) version of getRange :

var rownumber = 21;
var final_row = target_sheet.getRange(rownumber,1,1,target_sheet.getMaxColumns());

getMaxColumns() will give you the full row until the last column of your sheet, starting from the first column.

Alternatively, you can use getLastColumn() to get from the first column until the last column with content:

var rownumber = 21;
var final_row = target_sheet.getRange(rownumber,1,1,target_sheet.getLastColumn());

Answer 2

There are multiple ways to do this:

1. Template literals (template string)

var final_row = target_sheet.getRange(`${rownumber}:${rownumber}`);

2. Addition operator +

var final_row = target_sheet.getRange(rownumber + ':' + rownumber);

3. Array.prototype.join()

var final_row = target_sheet.getRange([rownumber, rownumber].join(':');
