- 第一次发布
- 第一次用JavaScript编写，虽然我在其他语言的经验。
我在Adobe公司的InDesign CS5.5工作。我在ID簿中有多个文件，每个文件包含不同数量的“章节”。本书包含一个索引文件，其中的主题标题以简写形式引用章节（例如，“第125章”变为“ch 125 no 3” - 注意“no x”部分不相关）。我的脚本的目标是创建文档间链接，当ID簿导出为PDF时，这些链接将增加显着的功能。用户将能够从索引跳转到章节，反之亦然。我认为脚本和我正在处理的问题会对其他人有用，但还没有找到任何帖子来解决我的问题。排版的JavaScript图书创建文本和内部文档超链接 - 速度异常慢
所有裁判（如“CH 125 1号”）在索引中特定的章节（“第125章”）获得的超链接到该章节的头部的位置。这部分脚本运行良好，运行速度很快。
另一半将在每个章节文字的末尾插入相应的主题标题，让这些段落在索引链接到相应的主题头部。 （换句话说，他们是交叉引用，但不是在ID方面真正的X-裁判，因为我想更好地控制他们和我的话题读书让我避开真正的X-裁判的）。这是脚本的一部分那让我把我的头撞在墙上。它几个小时运行几个小时，没有完成200章的书。请注意，出于测试目的，我只是在每章下的所需位置插入一段文本，而不是所有主题题头和链接。我知道从更小的文本集和从我的调试打印到控制台，脚本正在工作，而不是陷入无限循环。尽管如此，它的运行时间太长，如果我打断它，InDesign没有反应，我必须杀死它，所以甚至不能检查部分结果。
基于搜索/阅读论坛：我有禁用预检;禁用自动更新书页号码;将实时预览设置更改为延迟。我仍然怀疑缓慢可能与InDesign开销有关，但我不知道还有什么可以尝试的。
我很尴尬这个JS代码的风格有多糟糕，但目前我只需要它的工作，然后我可以改进它。
