这是一个奇怪的现象。我必须做一些有趣的解决方法才能让它发挥一点作用，但我们还有另一个绊脚石。
我一直在努力创建一个使用大型 .ind 文件的单独文档（使用 makeindex 从串联的小型单独 .idx 文件创建的索引），其想法是我最终将拥有一个指示子文档的单个文档，并且索引数据出现的页码。
为此，我必须定义一个收集所有索引条目的命令，如下所示：
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf}}}
结果是 myindex.idx 文件中的索引条目如下：
\indexentry{IndexedItemA : 55.iii!\href{Volume 1.pdf}{Volume 1.pdf}}{30}}
\indexentry{IndexedItemB : 23.vi!\href{Volume 3.pdf}{Volume 3.pdf}}{114}}
然而，在尝试创建目标 PDF 的超引用时存在问题。为了在特定页面打开 PDF，需要采用以下格式（感谢本板上的其他人指出了 hyperref 包中的 #page.xx 语法）：
\href{FILENAME#page.XX}{Link Text}
wihch 意味着需要使用散列标记声明 myindex 时，包含在 \newcommand 的输出流中，可能使用转义哈希标记 # as:
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf\#page.\thepage}}}
或根据我发现 某处 的某些片段，使用双哈希标记 as:
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf##page.\thepage}}}
前者导致在为正在索引的多个文档编译 Latex 源期间出现以下错误：
! Illegal parameter number in definition of \@gtempa.
<to be read again>
\thepage
l.31 \myindex{IndexedItemA}{55}{iii}
而后者会导致生成的 myindex.idx 文件中出现不需要的反斜杠：
\indexentry{IndexedItemA : 55.iii!\href {Volume 1.pdf\#page.33}{Volume 1}}{33}
这会导致目标 PDF 无法正确打开。
知道如何强制 new 命令输出哈希标记以支持 PDF 的超链接吗？
This is a strange one. I've had to do some interesting workarounds to get it to function even a little bit, but we have another stumbling block.
I've been struggling to create a separate document which employs a large .ind file (index created using makeindex from catenated, small individual .idx files), the idea being that I will eventually have a single document which indicates the SUB-documents and page numbers where the indexed data occurs.
To this end, I've had to define a command which collects all index entries as:
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf}}}
The result is index entries in the myindex.idx file as:
\indexentry{IndexedItemA : 55.iii!\href{Volume 1.pdf}{Volume 1.pdf}}{30}}
\indexentry{IndexedItemB : 23.vi!\href{Volume 3.pdf}{Volume 3.pdf}}{114}}
Yet, the problem exists in trying to create a hyperref to the target PDF. In order to open a PDF at a specific page, the following format needs to be employed (thanks to someone else on this board for pointing out the #page.xx syntax in the hyperref package):
\href{FILENAME#page.XX}{Link Text}
wihch means that a hash mark needs to be included in the output stream of the \newcommand when myindex is declared, possibly using an escaped hash mark # as:
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf\#page.\thepage}}}
or according to some fragment I found somewhere using a double-hash mark as:
\newcommand{\myindexer}[3]
{\index{myindex}{#1 : #2.#3!\href{\doctitle.pdf##page.\thepage}}}
The former results in the following error during compilation of the latex source for the multiple documents being indexed:
! Illegal parameter number in definition of \@gtempa.
<to be read again>
\thepage
l.31 \myindex{IndexedItemA}{55}{iii}
While the latter results in an unwanted backslash in the resulting myindex.idx file as:
\indexentry{IndexedItemA : 55.iii!\href {Volume 1.pdf\#page.33}{Volume 1}}{33}
which results in the target PDF not opening correctly.
Any idea how the newcommand can be forced to output the hash mark to support hyperlinking of PDFs in this way?

将
\href包装在\protect中怎么样？What about wrapping the
\hrefin\protect?你可以交换#和%的catcode：
然后用%来标记参数：
\newcommand{\myindexer}[3] {\index{myindex}{%1 : %2.%3!\href{\doctitle.pdf#page.\thepage}}}之后恢复通常的catcodes：
这有点笨拙，但即使某些东西干扰了通常的转义机制，它也应该可以工作，并且它允许在点
\myindexer< 处扩展\href使用/代码>。You can swap the catcode of # and %:
Then use % to mark parameters:
\newcommand{\myindexer}[3] {\index{myindex}{%1 : %2.%3!\href{\doctitle.pdf#page.\thepage}}}After that, restore the usual catcodes:
This is kind of clumsy, but it should work even if something interferes with usual escaping mechanisms, and it allows
\hrefto be exanded at the point\myindexeris used.
