google sheets script - select multiple a1 notation range - google-apps-script

Question

I'm opting for batch update of row colors using google apps script. However I cannot go for the usual range function, as the rows to be colored are not consecutive. So I thought, a1 notation would be helpful but unfortunately it looks like I can only pass one range of a1 notation and not multiple:
var a1Notations="A1:C1,A3:C3,A10,C10";
sheet.getRange(a1Notations).setBackground("red");
But I'm getting "Range not found" error.
Any ideas how can I make this work?
Thanks!

Answer 1

To multi-select a number of ranges and change the color:
var sheet = SpreadsheetApp.getActiveSheet();
var rangeList = sheet.getRangeList(['A1:C1','A3:C3','A10','C10']);
sheet.setActiveRangeList(rangeList).setBackground("red");
If you want to type a list in a dialog box:
function promptRangesList() {
var ui = SpreadsheetApp.getUi();
var response = ui.prompt('Comma-separated ranges list', 'E.g.: A1:C1,A3:C3,A10,C10 or C3,C7,C17,C56', ui.ButtonSet.OK_CANCEL);
Logger.log(response.getSelectedButton());
// Process the user's response.
if (response.getSelectedButton() == ui.Button.OK) {
if (response.getResponseText()!=='') {
var list = response.getResponseText().split(',');
Logger.log(list);
var rangeslist = SpreadsheetApp.getActiveSheet().getRangeList(list).setBackground("red");
Logger.log(rangeslist);
rangeslist.activate();
} else {
Logger.log('getResponseText empty');
}
} else if (response.getSelectedButton() == ui.Button.CANCEL) {
Logger.log('CANCELED');
} else {
Logger.log('The user clicked the close button in the dialog\'s title bar.');
}
}
Reference:
Class RangeList - Selects the list of Range instances
Class Sheet - Sets the specified list of ranges as the active ranges in the active sheet.
Prompt dialogs - A prompt is a pre-built dialog box that opens inside a Google Docs, Sheets, or Forms editor.

Put the range notations into an array, then loop through the array:
function setMultiRanges() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = ss.getActiveSheet();
var a1Notations=["A1:C1","A3:C3","A10","C10"];
var i=0,
arryLngth = a1Notations.length;
for (i=0;i<arryLngth;i+=1) {
//Logger.log(a1Notations[i]);
//Logger.log(typeof a1Notations[i]);
sh.getRange(a1Notations[i]).setBackground("red");
};
};

Answer 3

Set each range independently
sheet.getRange("A1:C1").setBackground("red");
sheet.getRange("A3:C3").setBackground("red");
sheet.getRange("A10:C10").setBackground("red");

According to the doc of Google Sheets' API V4 the way to select multiple ranges is to pass an array of ranges.
var ranges = ["'EVERYTHING'!A:A", "'EVERYTHING'!Z:Z"];
// I use Node.js, so my call to the API looks like this:
service.spreadsheets.values.batchGet({
spreadsheetId: spreadsheetId,
ranges: ranges
}, function(err, result) { ...
Then what you get is an array of data, [{first range}, {second range}, {etc...}]
