对于PROPERTY 函数，您可以获取对象的属性值。对象属性遵循 JavaScript 规则并且区分大小写。您可以在公式中使用 PROPERTY 函数：
=PROPERTY(dataexpression, propertypath)。
data_expression：表示对象数据。 接受其值为对象或对象函数结果的单元格引用。
property_path：表示对象中的属性路径，属性路径跟随对象深度。
点运算符是PROPERTY函数的简化：左边的值是对象或对对象的引用，右边的值是属性值，如果它包含任何无效字符，则可以用引号引起来。应该注意的是，使用 点运算符 可能会在Excel中引发错误。
例如:
window.onload = function() {
var spread = new GC.Spread.Sheets.Workbook(_getElementById("ss"));
spread.options.allowDynamicArray = true;
initSpread(spread);
};
function initSpread(spread) {
spread.setSheetCount(1);
spread.suspendPaint();
spread.suspendCalcService();
initSheet1(spread.getSheet(0));
spread.resumeCalcService();
spread.resumePaint();
}
function initSheet1(sheet) {
sheet.suspendPaint();
sheet.name('WebService');
sheet.setColumnWidth(0,27);
sheet.setColumnWidth(1,300);
sheet.setColumnWidth(2,168);
sheet.setColumnWidth(3,168);
sheet.setValue(0, 1, 'Enter full or partial country name');
var inputStyle = new GC.Spread.Sheets.Style();
inputStyle.backColor = "#FEF3CD";
sheet.setStyle(1,1,inputStyle);
sheet.setValue(3,1,"Name");
sheet.setValue(3,2,"Population");
sheet.setValue(3,3,"Language");
sheet.setValue(1,1,"united");
var headerStyle = new GC.Spread.Sheets.Style();
headerStyle.backColor = "rgb(222,235,246)";
headerStyle.font = "bold 11pt Calibri";
headerStyle.hAlign = 1;
var borderBottom = new GC.Spread.Sheets.LineBorder;
borderBottom.color = "black";
borderBottom.style = GC.Spread.Sheets.LineStyle.thin;
headerStyle.borderBottom = borderBottom;
sheet.setStyle(3,1,headerStyle);
sheet.setStyle(3,2,headerStyle);
sheet.setStyle(3,3,headerStyle);
for (var r = 4; r < 50; r++) {
sheet.setFormatter(r,1,'=IFERROR(@.name, "")');
sheet.setFormatter(r,2,'#,##0');
sheet.setFormatter(r,3,'#,##0');
}
sheet.setFormula(4,1,'=FILTERJSON(IF(LEN(B2)>3,WEBSERVICE("https://restcountries.com/v2/name/"&B2)))');
sheet.setFormula(4,2,'=B5#.population');
sheet.setFormula(4,3,'=B5#.languages.0.nativeName');
sheet.resumePaint();
}
function _getElementById(id) {
return document.getElementById(id);
}
