【问题描述】：

我有这个 google-apps-script 代码，用于获取一些 YT 频道并过滤其中一些：

    var popularChannels = YouTube.Channels.list('id, snippet, statistics', {
        id: resultsParentChannelIds.slice(i * 50, (i + 1) * 50)
    }).getItems().
    filter(
      ch => 
    ((channelIdFilter == "" || ch.id == channelIdFilter)
    && (subCountFilter == "" || ch.statistics.subscriberCount > subCountFilter)
    && (channelLocationFilter == "" || channel.snippet.country == undefined || channel.snippet.country == channelLocationFilter)
    && (channelNegativeLocationFilter == "" || channel.snippet.country == undefined || channel.snippet.country != channelNegativeLocationFilter)));

除了最后一个 NegativeLocation 过滤器之外，所有过滤器都是 ""。

但调试器在第一个过滤器之后停止而没有写入任何错误。

如何调试或了解问题所在？

【解决方案1】：

您在中途将 currentValue 变量从 ch 更改为 channel。

var popularChannels = YouTube.Channels.list('id, snippet, statistics', {
  id: resultsParentChannelIds.slice(i * 50, (i + 1) * 50)
}).getItems().
filter(
ch => 
((channelIdFilter == "" || ch.id == channelIdFilter)
&& (subCountFilter == "" || ch.statistics.subscriberCount > subCountFilter)
&& (channelLocationFilter == "" || ch.snippet.country == undefined || ch.snippet.country == channelLocationFilter)
&& (channelNegativeLocationFilter == "" || ch.snippet.country == undefined || ch.snippet.country != channelNegativeLocationFilter)));
