问题描述

是否有简单的方法来解析HTML页面以查找所使用的所有字体(或使用的所有字体堆栈)?

Is there easy way to parse a HTML page to find all the fonts used (or all the font stacks used)?

或者类似地,是否有一个脚本解析一个页面并返回包含和使用或包含哪些CSS规则但未使用?

Or similarly, is there a script that parses a page and returns which CSS rules are included and used or included and are not used?

示例:

如果我解析索引。 html ,我想知道使用了2个字体堆栈: font-family:Georgia,serif font-family :Arial,sans-serif

If I parse index.html, I want to know that 2 font stacks are used: font-family: Georgia, serif and font-family: Arial, sans-serif.

或者,如果我解析 index.html ,我想知道使用 style.css 的第10,12和15行。

Or, if I parse index.html, I want to know that lines 10, 12, and 15 of style.css are used.

我想象有人为此创建了一个应用程序?有人知道吗?

I imagine somewhere someone has created an app for this? Anyone know of anything?

推荐答案

感谢上面的一些回复,我把一个工具列出所有独特的字体堆栈,然后根据需要使用特定的字体堆栈突出显示所有DOM元素。

Thanks to some of the responses above, I put together a tool to list all unique font stacks and then highlight all DOM elements using a specific font stack, if desired.

这是文件;顶部有几个示例显示了使用它的不同方法: https://gist.github.com / macbookandrew / f33dbbc0aa582d0515919dc5fb95c00a

Here’s the file; there are a couple of examples at the top showing different ways to use it: https://gist.github.com/macbookandrew/f33dbbc0aa582d0515919dc5fb95c00a

简而言之,下载并在源代码中包含该文件,或将其复制/粘贴到您的JS控制台中,然后运行 console.log(styleInPage('fontFamily')); 获取所有唯一字体堆栈的数组。

In short, download and include the file in your source code, or copy/paste it into your JS console, then run console.log(styleInPage('fontFamily')); to get an array of all unique font stacks.

示例输出在stackoverflow.com上:

Example output on stackoverflow.com:

Array[3]
    0: "Arial, "Helvetica Neue", Helvetica, sans-serif"
    1: "BlinkMacSystemFont"
    2: "Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif"

然后突出显示具有特定字体堆栈的所有元素,运行 highlightInPage(4)(从数组abo传入基于0的数组键阳离子)。要清除所有亮点,请运行 clearHighlights()

Then to highlight all elements with a specific font stack, run highlightInPage(4) (pass in the 0-based array key from the array above). To clear all highlights, run clearHighlights().
