Improve your documentation with JavaScript
使用 JavaScript 增强您的文档
======
Open source software projects often have a very diverse user group. Some users might be very adept at using the system and need very little documentation. For these power users, documentation might only need to be reminders and hints, and can include more technical information such as commands to run at the shell. But other users may be beginners. These users need more help in setting up the system and learning how to use it.
开源软件项目通常拥有非常多样化的用户人群。有些用户非常擅长使用该系统，并且只需要很少的文档。对于这些实力派的用户。文档只需要提供必要的提示，并且可以包含更多的技术信息，比如说在 shell 中运行的命令行。有些用户可能只是初学者。这些用户需要更多的帮助来设置系统并学习如何使用它。
Writing documentation that suits both user groups can be daunting. The website's documentation needs to somehow balance "detailed technical information" with "providing more overview and guidance." This is a difficult balance to find. If your documentation can't meet both user groups, consider a third option — dynamic documentation.
写一个同时适合这两个用户群体的文档是令人生畏的。网站文档需要在 “提供详细的技术信息” 和 “提供更多的概述和指导” 之间寻求一个平衡。这是一个很难找到的平衡。如果你的文档不能同时满足这两个用户人群，那么考虑一下另外一个选择 —— 动态文档。

You can use the example where documentation needs to suit both expert and novice users. In the simplest case, you can use a made-up music player called AwesomeProject.
你可以把例程添加的你的文档中需要同时满足 <ruby>专家<rt>expert</rt></ruby> 和 <ruby>初学者<rt>novice</rt></ruby> 的地方。在这个例程中，你可以使用一个叫做 AwesmeProject 的虚构的音乐播放器。
You can write a short installation document in HTML that provides instructions for both experts and novices by using the class feature in HTML. For example, you can define a paragraph intended for experts by using:
你可以用 HTML 编写一个简短的安装文档，通过 HTML 的 <ruby>类<rt>class</rt></ruby> 功能同时为专家和初学者提供操作指南。例如，你可以用下面的代码来为专家定义一个段落：
```
<p class="expert reader">
```
This assigns both the expert class and the reader class. You can create a parallel set of instructions for novices using:
这就同时指派了专家类 和读者类。 你可以用下面的代码来为初学者创建一个相同的段落。
```
<p class="novice reader">
```
The complete HTML file includes both paragraphs for novice readers and experts:

We can apply some basic styling to the document to highlight any element with the reader, expert, or novice classes. To make the different text classes easier to differentiate, let's set the reader class to an off-white background color, expert to a dark red text color, and novice to a dark blue text color:
我们可在文档中添加一些简单的样式来为 <ruby>读者<rt>reader</rt></ruby>，<ruby>专家<rt>expert</rt></ruby> 或者 <ruby>初学者<rt>novice</rt></ruby> 突出任何元素。为了使不同的文本更容易区分，让我们把读者类的背景颜色设置成米白色，专家类的字体颜色设置为深红色，初学者的字体颜色则设置为深蓝色。

These styles help the two sections stand out when you view the page in a web browser. Both paragraphs with the installation instructions have an off-white background color because they both have the reader class. The first paragraph uses dark red text, as defined by the expert class. The second installation paragraph is in dark blue text, from the novice class:

### Add JavaScript controls
### 添加 JavaScript 控件
With these classes applied, you can add a short JavaScript function that shows just one of the content blocks. One way to write this function is to first set `display:none` to all of the elements with the reader class. This hides the content so it won't display on the page. Then the function should set `display:block` to each of the elements with the class you want to display:
这些类的应用，使你可以添加一些简单的 JavaScript 函数，只显示其中一个内容块。一个方法是，首先给所有的读者类元素设置 `display:none` 。这会将内容隐藏，使其不会在页面上显示。然后，用函数将你想显示的类元素设置为 `display:block` :

To use this JavaScript in the HTML document, you can attach the function to a button. Since the `readerview`function takes an audience as its parameter, you can call the function with the audience class that you want to view, either novice or expert:
要在 HTML 文档中使用这个 JavaScript，你可以吧这个功能附加到一个按钮上。由于 `readerview` 函数需要一个<ruby>听众<rt>audience</rt></ruby>（这应该是相对那个虚拟音乐播放器来说的）作为参数，你可以使用你想查看的听众类别来调用这个函数，可以是<ruby>读者<rt>reader</rt></ruby>，<ruby>专家<rt>expert</rt></ruby> 或者 <ruby>初学者<rt>novice</rt></ruby> 。

点击任何一个按钮都将只显示用户想要阅读的文本。例如，如果你点击了 “<ruby>阅读初学者内容<rt>view novice text</rt></ruby>” 按钮，你就只会看到蓝色段落。

Clicking the “view expert text” button hides the novice text and shows only the expert text in red:
点击 “<ruby>阅读专家内容<rt>view expert text</rt></ruby>” 按钮，就会隐藏初学者文本，只显示红色的专家文本。

### Extend this to your documentation
### 将此扩展到你的文档
If your project requires you to write multiple how-to documents for different audiences, consider using this method to publish once and read twice. Writing a single document for all your users makes it easy for everyone to find and share the documentation for your project. And you won't have to maintain parallel documentation that varies in just the details.
如果你的项目需要你为不同的听众编写多个操作文档，你可以考虑使用这种方法，一次发布，多次阅读。为所有的用户编写一个文档，是每个人都能很容易的发现和分享你项目的文档。而你也不必同时维护尽在细节上有所不同的多个文档。
