这段代码subMaterialNames 要存储resultName字符串subMaterialNames 应该怎么声明？请帮我补充代码let subMaterialNames = ; getMaterialChildrenOutSubMaterialsWithContainersT_ResultforEachresult = subMaterialNames

可以声明subMaterialNames为一个空数组，如下所示：

let subMaterialNames = []; getMaterialChildrenOut.SubMaterialsWithContainers.T_Result.forEach(result => { subMaterialNames.push(result.Name); });
