Use footnote multiple times in HTML Quarto


I would like to use a single footnote multiple times in HTML Quarto. The problem is that once I create a footnote and use it twice, it will be shown as two footnotes. Here is a reproducible example:

---
title: "Footnote multiple times"
editor: visual
format: html
---

Some example text for a footnote[^1].

Some example text for same footnote[^1].

[^1]: Example footnote.

Output:

enter image description here

As you can see, the footnote is shown as two separate footnotes (duplicated) while I created one footnote. So I was wondering if anyone knows how to create one footnote and use it multiple times in HTML Quarto?


Solution

  • We can sort of mimic how quarto would have generated the html code creating for footnotes to get similar appearances (that's why I have used r function so that I don't have to write the same thing multiple times).

    ---
    title: "Footnote multiple times"
    format: html
    ---
    
    ```{r}
    #| echo: false
    
    gen_fn <- function(n, id) {
      # n is number of footnote
      # id is a unique id for that footnote
      paste0('<a href="#',id, '" class="footnote-ref" role="doc-noteref" aria-expanded="false"><sup>', n, '</sup></a>')
    }
    ```
    
    Some example text for a footnote`r gen_fn(1, "fn1")`
    
    Some example text for same footnote`r gen_fn(1, "fn1")`
    
    Another text containing different footnotes`r gen_fn(2, "fn2")`
    
    ```{=html}
    <footer>
      <h2>Footnotes</h2>
      <ol  style="padding-left: 1rem;">
        <li id="fn1"><p>Example footnote.</p></li>
        <li id="fn2"><p>More footnote.</p></li>
      </ol>
    </footer>
    ```
    

    multiple references to same footnote
