Javascript Google应用程序脚本-映射时出错-类型错误：无法读取属性'；地图'；未定义的

javascript arrays google-apps-script mapping

Javascript Google应用程序脚本-映射时出错-类型错误：无法读取属性'；地图'；未定义的,javascript,arrays,google-apps-script,mapping,google-sheets-api,Javascript,Arrays,Google Apps Script,Mapping,Google Sheets Api,在社区的指导下，我最近了解了如何更新给定谷歌表单的背景颜色 我试图将此应用于我的实际工作表，但遇到了错误代码类型错误：无法读取未定义的属性“映射” 我的测试表中没有问题的代码如下： var TestArray = Sheets.Spreadsheets.get("1eAq-RbtrCSMRPZ0p7XIpG3vd29yL-3SQ3D3JGyiUhKg", { ranges:"TestBackgroundSheet!A1:AD39", fields:&

在社区的指导下，我最近了解了如何更新给定谷歌表单的背景颜色

我试图将此应用于我的实际工作表，但遇到了错误代码<代码>类型错误：无法读取未定义的属性“映射”

我的测试表中没有问题的代码如下：

var TestArray = Sheets.Spreadsheets.get("1eAq-RbtrCSMRPZ0p7XIpG3vd29yL-3SQ3D3JGyiUhKg", {
   ranges:"TestBackgroundSheet!A1:AD39", fields:"sheets(data(rowData(values(effectiveFormat.backgroundColor))))"
 });
 
 var backgroundColors = TestArray["sheets"][0]["data"][0]["rowData"]
                      .map(row => row["values"]
                      .map(value => value["effectiveFormat"]["backgroundColor"]));
然后我将这些代码复制并粘贴到我的实际项目中。为了排除故障，我甚至将测试项目中的精确表复制到实际项目中。代码如下所示：

var TestArray = Sheets.Spreadsheets.get("1pcIKNUFmkk0d-UGg1sXl5xbsJC2WhocIHpM3et-CMgo", {
   ranges:"TestBackgroundSheet!A1:AD39", fields:"sheets(data(rowData(values(effectiveFormat.backgroundColor))))"
 });
 
 var backgroundColors = TestArray["sheets"][0]["data"][0]["rowData"]
                      .map(row => row["values"]
                      .map(value => value["effectiveFormat"]["backgroundColor"]));
正如您所看到的，除了不同的SheetID之外，代码完全相同。尽管如此，我仍然得到了
TypeError:cannotreadproperty'map'，undefined
错误

错误代码引用了第172行，该行是
.map（value=>value[“effectiveFormat”][“backgroundColor”）

编辑：


编辑#2：

包含了Rafa的代码后，我得到了这个错误代码->SyntaxError:Unexpected token，在JSON的位置1（第177行，文件“macros”）

包含的代码如下


var TestArray = Sheets.Spreadsheets.get("1pcIKNUFmkk0d-UGg1sXl5xbsJC2WhocIHpM3et-CMgo", {
      ranges:"TestBackgroundSheet!A1:AD39",
      fields:"sheets(data(rowData(values(effectiveFormat.backgroundColor))))"
    });
     
    var rowData = TestArray["sheets"][0]["data"][0]["rowData"]
    .map(row => row.getValues()).toString()
    
    var backgroundColors = JSON.parse("[" + rowData + "]")
    .map(value => {
         let v = value["effectiveFormat"]
         return v ? v["backgroundColor"] : null
         })



编辑#3：

具有以下代码的行数据记录器


for (var x = 0; x < 40; x++) {
      Logger.log(x + JSON.stringify(TestArray["sheets"][0]["data"][0]["rowData"][x]));
    }

答复:
并非
行[“values”]
的所有元素都有数据，因此当该行没有数据时，无法运行
.map（value=>value[“effectiveFormat”][“backgroundColor”）

更多信息：
您已经使用API获取了数据


Sheets.Spreadsheets.get("1eAq-RbtrCSMRPZ0p7XIpG3vd29yL-3SQ3D3JGyiUhKg")


并使用字段掩码对其进行相应过滤。作为响应，您得到的数据将是工作表中的所有内容，甚至是没有背景颜色数据的单元格。因此，您无法像这样映射每一行，因为您将尝试在不存在
effectiveFormat
元素的地方引用它

修正：
您可以使用三元运算符来解决此问题；如果元素
值[“effectiveFormat”]
不存在，您只需返回
null
：


var rowData = TestArray["sheets"][0]["data"][0]["rowData"]
    .map(row => row.getValues()).toString()

var backgroundColors = JSON.parse("[" + rowData + "]")
    .map(value => {
        let v = value["effectiveFormat"]
        return v ? v["backgroundColor"] : null
    })


NB:该API还将在响应中返回JSON对象中的函数，您可以在应用程序脚本中使用这些函数。这很方便，因为直接引用
行[“值”]
可以返回对象而不是数据：


console.log(TestArray["sheets"][0]["data"][0]["rowData"]
            .map(row => row["values"]))

在第一个
.map（row=>row.getValues（））
之后的
toString（）
调用在将数据放回第二个映射函数之前通过了该调用

我希望这对你有帮助
