自定义函数参数解析

FactorialFunction.prototype.evaluate = function (arg) {
  var length = arguments.length;
  for (var i = 1; i < length; i++) {
    var argument = arguments[i];
    if (typeof argument == "string" || typeof argument == "number") {
      console.log("参数" + i + "为" + argument);
    } else {
      var sheet = argument.getSource().getSheet();
      var sheetName = sheet.name();
      console.log("参数" + i + "sheetName为：" + sheet.name());
      var r = argument.getRow();
      var c = argument.getColumn();
      var rc = argument.getRowCount();
      var cc = argument.getColumnCount();
      var range = new GC.Spread.Sheets.Range(r, c, rc, cc);
      var string = GC.Spread.Sheets.CalcEngine.rangeToFormula(
        range,
        0,
        0,
        GC.Spread.Sheets.CalcEngine.RangeReferenceRelative.allRelative
      );
      var setFormulaString = "" + sheetName + "!" + string;
      console.log("参数" + i + "为" + setFormulaString);
    }
  }
  return "anything";
};
