在Markdown规范中没有这样的指令，抱歉。

Github会自动从你的标题中解析锚标记。所以你可以这样做:

[Custom foo description](#foo)

# Foo

在上面的例子中，Foo头生成了一个名为Foo的锚标记

注意:所有标题大小只有一个#，#和锚点名称之间没有空格，锚点标签名称必须小写，如果有多个单词，则用破折号分隔。

[click on this link](#my-multi-word-header)

### My Multi Word Header

更新

潘多克也不例外。

pandoc手册解释了如何使用头文件的标识符链接到头文件。我没有检查其他解析器对此的支持，但据报道，它不能在github上工作。

标识符可以手动指定:

## my heading text {#mht}

Some normal text here,
including a [link to the header](#mht).

或者您可以使用自动生成的标识符(在本例中是#my-heading-text)。在pandoc手册中都有详细的解释。

注意:这只适用于转换为HTML, LaTex, ConTeXt, Textile或AsciiDoc。

因为在评论中提到了MultiMarkdown作为一个选项。

在MultiMarkdown中，内部链接的语法很简单。

对于文档中的任何标题，只需以这种格式给出标题名称[heading][]以创建内部链接。

Cross-References An oft-requested feature was the ability to have Markdown automatically handle within-document links as easily as it handled external links. To this aim, I added the ability to interpret [Some Text][] as a cross-link, if a header named “Some Text” exists. As an example, [Metadata][] will take you to # Metadata (or any of ## Metadata, ### Metadata, #### Metadata, ##### Metadata, ###### Metadata). Alternatively, you can include an optional label of your choosing to help disambiguate cases where multiple headers have the same title: ### Overview [MultiMarkdownOverview] ## This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers. If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence. In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.

只需遵循[text](#link)语法并遵循以下指导原则:

把字母和数字原封不动地写下来 用破折号-替换空格 删除其余的字符

举个例子，如果你有这些部分:

# 1. Python

# 2. c++

# 3. c++11

# 4. asp.net-core

您可以使用以下命令添加引用:

[1. Python](#1-python)
[2. c++](#2-c)
[3. c++11](#3-c11)
[4. asp.net-core](#4-aspnet-core)

注意asp.net-core如何变成aspnet-core, 1。Python变成了1-python，等等。

在pandoc中，如果在生成html时使用——toc选项，将生成一个包含到章节的链接的目录，并从章节标题返回到目录。它类似于pandoc编写的其他格式，如LaTeX、rtf、rst等。对于命令

pandoc --toc happiness.txt -o happiness.html

这里有一点降价:

% True Happiness

Introduction
------------

Many have posed the question of true happiness.  In this blog post we propose to
solve it.

First Attempts
--------------

The earliest attempts at attaining true happiness of course aimed at pleasure. 
Soon, though, the downside of pleasure was revealed.

将产生这个作为html的主体:

<h1 class="title">
    True Happiness
</h1>
<div id="TOC">
    <ul>
        <li>
            <a href="#introduction">Introduction</a>
        </li>
        <li>
            <a href="#first-attempts">First Attempts</a>
        </li>
    </ul>
</div>
<div id="introduction">
    <h2>
        <a href="#TOC">Introduction</a>
    </h2>
    <p>
