serviceImpl.save(location, false, false);
查看指定的第 49 行和周围的 for 循环语法，我没有看到问题，我错过了什么吗？
谢谢
更新 使用 AP 的建议进行更改，我得到一个新错误：当前代码（错误行 3：缺少；之前的语句）：
function runScript()
'use strict';
let survey = newDocument,
statusQuery = new AeSpcsrvySDTO();
logger.fine('Space survey [' + survey.spaceSurvey + ']');

return;
logger.fine('Space survey [' + survey.spaceSurvey + ']' +

for (let location in Iterator(survey.aeSpcsrvyLocDTOList))
logger.fine('Space survey [' + location.spaceSurvey + ']' +

if (usage.usageCode && usage.usagePercent
// There's a validation for <= 100, but not for > 0.
&&
usage.usagePercent.compareTo(BigDecimal.ZERO) > 0)
let proratedUsagePercent = usage.usagePercent.multiply(proration);
if (proratedUsagePercent.compareTo(highestUsagePercent) > 0 ||
(proratedUsagePercent.compareTo(highestUsagePercent) == 0 &&
usage.usageCode.compareTo(highestUsage.usageCode) < 0))
highestUsage = usage;
highestUsagePercent = proratedUsagePercent;
logger.fine('New highest usage percent is [' + highestUsagePercent + ']');
if (highestUsage)
// Look up the location and update the usage.
let locationKey = new AeBLocDPK(highestUsage.regionCode, highestUsage.facId, highestUsage.bldg, highestUsage.locId),
serviceImpl = new PropertyServiceImpl(SystemContext.getInstance());
let location = serviceImpl.findByPrimaryKey(locationKey, false);
location.usageCode = highestUsage.usageCode;
serviceImpl.save(location, false, false);
【问题讨论】：
可以考虑使用.forEach 比如survey.aeSpcsrvyLocDTOList.forEach(element => do something;)
您能否使用以下格式格式化您的代码：jsbeautifier.org
【参考方案1】：
不确定你想用这个块实现什么：
let (proratedUsagePercent = usage.usagePercent.multiply(proration))
if (proratedUsagePercent.compareTo(highestUsagePercent) > 0
|| (proratedUsagePercent.compareTo(highestUsagePercent) == 0
&& usage.usageCode.compareTo(highestUsage.usageCode) < 0))
highestUsage = usage;
highestUsagePercent = proratedUsagePercent;
logger.fine('New highest usage percent is [' + highestUsagePercent + ']');
您不能在 let expression 前面添加块，也许将其更改为：
let proratedUsagePercent = usage.usagePercent.multiply(proration)
if (proratedUsagePercent.compareTo(highestUsagePercent) > 0
|| (proratedUsagePercent.compareTo(highestUsagePercent) == 0
&& usage.usageCode.compareTo(highestUsage.usageCode) < 0))
highestUsage = usage;
highestUsagePercent = proratedUsagePercent;
logger.fine('New highest usage percent is [' + highestUsagePercent + ']');
另外：也许您的浏览器可能不支持let declaration 之外的strict mode。将其替换为 var 或将 'use strict;'（带引号）添加到函数顶部。
【讨论】：
尝试 AP. 的建议，我的错误信息移至第 29 行：缺少；在第 29 行的+ ' facility [' + occupancy.facId + ']'
抱歉忘了转换行号，它是上面代码中的第 2 行：let (survey = newDocument, statusQuery = new AeSpcsrvySDTO())
是的，这将变成：let survey = newDocument, statusQuery = new AeSpcsrvySDTO() 和 missing ; before statement on that line 2 的新错误，无论有没有，我什至尝试将分号添加到末尾那让声明以上是关于缺少javascript；在 for 循环初始化程序之后（来源不明的主要内容，如果未能解决你的问题，请参考以下文章
