通过 javascript 对 CD-Rom 上的静态 HTML 文件进行全文

问题描述

我将在 CD-Rom 上提供一组静态 HTML 页面；这些页面需要在没有任何 Internet 访问权限的情况下完全可见.

I will be delivering a set of static HTML pages on CD-Rom; these pages need to be fully viewable with no Internet access whatsoever.

我想为这些页面的内容提供全文搜索(类似 Lucene)，它应该可以从 CD-Rom 中正常工作"，而无需在客户端计算机上安装软件.

I'd like to provide a full-text search (Lucene-like) for the content of those pages, which should "just work" from the CD-Rom with no software installation on the client machine.

在 javascript 中实现搜索引擎将是完美的解决方案，但我很难找到任何看起来可靠/当前/流行的...?

A search engine implementation in javascript would be the perfect solution, but I have trouble finding any that looks solid / current / popular...?

我确实找到了这些:+ jsFind+ js-search

I did find these: + jsFind + js-search

但这两个项目似乎都相当不活跃?

but both projects seem rather inactive?

除了特定的 javascript 搜索引擎之外，另一种解决方案是能够从 javascript 访问本地 Lucene 索引:索引本身将使用 Lucene 构建并与 HTML 文件一起复制到 CD-Rom.

Another solution, besides a specific search engine in javascript, would be the ability to access local Lucene indices from javascript: the indices themselves would be built with Lucene and copied to the CD-Rom along with the HTML files.

编辑:自己构建(见下文).

Edit: built it myself (see below).

推荐答案

其实我自己做的.

现有的解决方案(我能找到)没有说服力.

The existing solutions (that I could find) were unconvincing.

我希望能够搜索显示为一页的很长的树(ul/li/ul...)；它包含 5000 多个项目.

I wanted to be able to search a very long tree (ul/li/ul...) that is displayed as one page; it contains 5000+ items.

在一个页面上显示这么长的树听起来有点奇怪，但实际上折叠/展开它比单独的页面更直观，而且由于我们离线，下载时间不是问题(解析时间是，不过，Chrome 很棒 ;-)

It sounds a little weird to display such a long tree on one page but in fact with collapse / expand it's much more intuitive than separate pages, and since we're offline, download times are not a problem (parsing times are, though, but Chrome is amazing ;-)

现代浏览器(无论如何都是FF和Chrome)提供的搜索"功能有两个大问题:它们只搜索页面上的可见项，并且无法搜索不连续的单词.

The "search" function provided with modern browsers (FF and Chrome anyway) have two big problems: they only search visible items on the page, and they can't search non-consecutive words.

我希望能够搜索折叠的项目(在屏幕上不可见)；我想在搜索一三"时找到一二三"(就像谷歌/Lucene)；我只想打开包含找到的项目的树的分支.

I want to be able to search collapsed items (not visible on the screen); I want to find "one two three" when searching "one three" (just like with Google / Lucene); and I want to open just the branches of the tree containing found items.

所以，我所做的是:

1. 创建单词的倒排索引 <-> 列表中项目的 ID(通过 xslt)(文档中大约 4500 个唯一单词)
2. 将此索引转换为一堆 javascript 数组(一个单词 = 一个数组，包含 id)
3. 搜索时，与搜索词表示的数组相交
4. 第 3 步返回一个 ID 数组，然后我可以打开/突出显示该数组

它完全符合我的需要，而且速度非常快.更好的是，因为它从独立的索引"(id 数组)中搜索，所以它甚至可以在浏览器中没有加载列表时进行搜索！

It does exactly what I needed and it's really fast. Better yet, since it searches from an independant "index" (arrays of ids) it can search when the list is not even loaded in the browser!
