  1. 第一次发帖
  2. 第一次用 JavaScript 写，虽然我有其他语言的经验。

我正在使用 Adob​​e InDesign CS5.5。我在 ID Book 中有多个文件，每个文件都包含不同数量的“章节”。本书包含一个索引文件，其中包含以缩写形式引用章节的主题标题（例如，“CHAPTER 125”变为“ch 125 no 3”——注意“no x”部分无关紧要）。我的脚本的目标是创建文档间链接，当 ID Book 导出为 PDF 时，这些链接将增加重要的功能。用户将能够从索引跳转到章节，反之亦然。我认为我正在处理的脚本和问题对其他人有用，但还没有找到任何帖子来解决我的问题。

特定章节（“CHAPTER 125”）索引中的所有参考文献（如“ch 125 no 1”）都会获得指向该章节头部位置的超链接。这部分脚本运行良好且运行迅速。

另一半将在每章文本的末尾插入相应的主题标题，并使这些段落链接回索引中的相应主题标题。（换句话说，它们是交叉引用，但在 ID 术语中不是真正的 x-ref，因为我希望对它们进行更多控制，并且我对该主题的阅读告诉我要避开真正的 x-ref。）这是脚本的一部分这让我把头撞在墙上。它运行了几个小时，却没有完成一本 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，而不是所有主题标题和链接。我从较小的文本集和调试打印到控制台中知道脚本正在工作，而不是陷入无限循环。然而，它运行的时间太长了，如果我打断它，

基于搜索/阅读论坛：我禁用了预检；禁用自动更新书页码；将实时预览设置更改为延迟。我仍然怀疑速度缓慢可能与 InDesign 开销有关，但我不知道还能尝试什么。

我对这段 JS 代码的风格可能有多糟糕感到尴尬，但目前我只需要它工作，然后我可以改进它。

尝试打开所有链接到它们的交叉引用文件。

我可以建议一些可能会加快速度的改进。首先，您在这里有大量的全局变量，您可以使用函数将注意力集中在更少的范围内。拥有许多全局变量在性能方面会付出很大的代价。

话虽如此，我不会一次打开本书的每一个文档，而是一个一个地处理它们。请注意，grep 调用非常昂贵，因此您可以尝试查看您的模式。

另一个是 $.writeln 命令的广泛使用。避免它，尤其是在循环中。更喜欢易于设置的报告库。

最后，我尝试以“更好”的方式重写您的代码，但是很难在清楚地了解您的需求并且没有要处理的文件的情况下构建整个脚本。但我希望下面的代码片段能帮助您开始重写您的代码并说明显着的时间改进。

var debug = true;

var log = function(msg) {
	
	var l = File (Folder.desktop+"/log.txt" );
	
	if ( !debug ) return;
	
	l.open('a');
	l.write(msg);
	l.close();
};

var main = function() {
	
	var bookFile, uil = app.scriptPreferences.userIntercationLevel;
	
	log("The party has started");
	
	bookFile = File.openDialog("Choose an InDesign Book File", "Indb files: *.indb");
	
	if (!bookFile) return;
	app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
	
	try {
		processBookFile ( bookFile );
	}
	catch(err) {
		alert(err.line+"///"+err.message);
	}

	app.scriptPreferences.userInteractionLevel = uil;
};

function processBookFile ( bookFile ) {
	var book = app.open ( bookFile ),
	bks = book.bookContents,
	n = bks.length;
	
	while ( n-- ) {
		File(bks[n].name)!="Index.indd" && processBookContent ( bks[n] );
	}
}

function processBookContent ( bookContent ) {
	var bcf = bookContent.fullName,
	doc = app.open ( bcf, debug );
	
	//DEAL WITH HEADINGS
	processHeadings ( doc );
	
	//DEAL WITH CHAPTERS
	processHeadings ( doc );
	
	//add hyperlinks
	addHyperlinks( doc);
}



function processHeadings (doc){
	var props = {
		findWhat : "^[\\u\\d \\:\\;\\?\\-\\'\\\"\\$\\%\\&\\!\\@\\*\\#\\,\\.\\(\\)]+[\\u\\d](?=\\.|,)",
		appliedParagraphStyle : "Main"
	},
	found = findGrep(doc, props),
	n = found.length;
	
	while ( n-- ) {
		doc.hyperlinkTextDestinations.add(doc, { name: found[i].contents });
	}
};

function processChapters (doc ) {
	var props = {
		findWhat : "^CHAPTER \\d+",
		appliedParagraphStyle : "chapter"
	},
	found = findGrep(doc, props),
	n = found.length;
	
	while ( n-- ) {
		doc.hyperlinkTextDestinations.add(found[n], found[n].contents);
	}
}

function findGrep(doc, props){
	app.findGrepPreferences = app.changeGrepPreferences = null;	
	app.findGrepPreferences.properties = props;
	return doc.findGrep();
}

function addHyperlinks (doc){
	//a logic of yours
};


main();
