Google Spreadheets Scripts: check if cell is empty

Question

I want to input a variable in a cell only if the cell is empty. The if statement, however, does not work. Any advice?

var ss=SpreadsheetApp.getActiveSpreadsh

No need to extact the value to determine if the cell is empty. Google Spreadsheet API already has a method for this: Range - isBlank method

var cell = r.getCell(rws-1, 10);

if (cell.isBlank()) {
    cell.setValue("foo");
}
