如何根据 Google Apps 脚本中的 .getValues( ) 方法的结果对单元格应用条件格式？

Question

I am writing this script to change the formatting of a row of checkboxes that total 0 selections. In my data validation, "true" = 1 and "false" = 0. The range is represented as an object [ ][ ].

The logic below determines which rows need to be formatted, but how do I actually apply the formatting to this row? I am having trouble accessing the row's formatting because I am working at the value level with the resulting object [ ] [ ].

Here is what the end result should look like: Camping Gear Tally

(I recognize there is probably an easy way to do this with conditional formatting built in, but I'm just trying to get better at coding)

 function updateFormatting() { var cellValues = SpreadsheetApp.getActiveSheet().getRange("C2:I37").getValues(); for (let i = 0; i < cellValues.length; i++) { let rowTotal = 0; for (let j = 0; j < cellValues[i].length; j++) { rowTotal += cellValues[i][j]; } if (rowTotal == 0) { /* Apply formatting to this row */ } } }

Thank you for your guidance!

I believe your goal is as follows.

• You want to set the background color of the rows that all checkboxes of columns "C" to "I" are unchecked.
• In your situation, the values of the checked and the unchecked checkboxes are 1 and 0 , respectively.

Modification points:

• When the values of the checked and the unchecked checkboxes are 1 and 0 , respectively, when those values are retrieved by getValues , those are retrieved as the string type. So, in your script, when rowTotal += cellValues[i][j]; is run, the values are added as the string. Please be careful about this.
• About /* Apply formatting to this row */ , when the script for setting the cell format is put in a loop, the process cost will be high.

When these points are reflected in your script, how about the following modification?

Modified script:

function updateFormatting() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var cellValues = sheet.getRange("C2:I37").getValues();
  var ranges = [];
  for (let i = 0; i < cellValues.length; i++) {
    let rowTotal = 0;
    for (let j = 0; j < cellValues[i].length; j++) {
      rowTotal += Number(cellValues[i][j]);
    }
    if (rowTotal == 0) {
      var row = i + 2;
      ranges.push(`C${row}:I${row}`);
    }
  }
  sheet.getRangeList(ranges).setBackground("#fce5cd");
}

• In this modification, the range list is created in a loop. And, it is used with sheet.getRangeList(ranges).setBackground("#fce5cd") and the background color of rows are set as #fce5cd .
