Script to Change Row Color when a cell changes text

Question

I have a Google spreadsheet where I keep a list of bugs and whenever I fix a bug I change the status from "Not Started" to "Complete". I want to write a script for the Google Docs spreadsheet such that whenever I change the status to "Complete" the entire row gets highlighted in a certain color.

I already know that Google spreadsheet already has "change color on text" but that function only changes the color of the cell and does not change the color of the entire row.

Answer 1

//Sets the row color depending on the value in the "Status" column.
function setRowColors() {
  var range = SpreadsheetApp.getActiveSheet().getDataRange();
  var statusColumnOffset = getStatusColumnOffset();

  for (var i = range.getRow(); i < range.getLastRow(); i++) {
    rowRange = range.offset(i, 0, 1);
    status = rowRange.offset(0, statusColumnOffset).getValue();
    if (status == 'Completed') {
      rowRange.setBackgroundColor("#99CC99");
    } else if (status == 'In Progress') {
      rowRange.setBackgroundColor("#FFDD88");    
    } else if (status == 'Not Started') {
      rowRange.setBackgroundColor("#CC6666");          
    }
  }
}

//Returns the offset value of the column titled "Status"
//(eg, if the 7th column is labeled "Status", this function returns 6)
function getStatusColumnOffset() {
  lastColumn = SpreadsheetApp.getActiveSheet().getLastColumn();
  var range = SpreadsheetApp.getActiveSheet().getRange(1,1,1,lastColumn);

  for (var i = 0; i < range.getLastColumn(); i++) {
    if (range.offset(0, i, 1, 1).getValue() == "Status") {
      return i;
    } 
  }
}
