How do I pass a number to .hideRow()? - google-apps-script

Question

I got the following script from #Mike Grace's website:
// Deletes rows in the active spreadsheet that contain 'Yes' in column A
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
var values = rows.getValues();
var rowsDeleted = 0;
for (var i = 0; i <= numRows - 1; i++) {
var row = values[i];
if (row[0] == 'Yes') {
sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
rowsDeleted++;
}
}
}
The script works well, but I would like to make a change to it, instead of calling .deleteRow() I want to use .hideRow() instead.
Because the .hideRow() method only accepts a range as far as I understand, I'm getting the following error:
How do I modify this script so that it hides the row instead of deleting them?

Answer 1

there are different hideRow / s () methods, one of them takes a row number as argument.
your code can be simplified like this :
function hideRowsWithYes() {
var sheet = SpreadsheetApp.getActiveSheet();
var values = sheet.getDataRange().getValues();
for (var i = 0; i < values.length; i++) {
if (values[i][0] == 'Yes') {
sheet.hideRows(1+i);
}
}
}
As usual, autocomplete makes the job easier...
Edit following comment :
to unhide row we don't have a simple method with row index so we need to define the range... code goes like this (i has a +1 because values is an array that starts from 0 while sheets are indexed from 1)
function unHideRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var values = sheet.getDataRange().getValues();
var row;
var maxCol = sheet.getMaxColumns();
for (var i = 0; i < values.length; i++) {
if (values[i][0] == 'Yes') {
row = sheet.getRange(1+i, 1, 1, maxCol);
sheet.unhideRow(row);
}
}
}
