Instance Method Details

#footnote_html(id, time) ⇒ Object

This is the method that will actually spit out the div that the footnote’s content is in. This will generally be called after all of the paragraph’s text has been spit out so that the footnotes can be appended after. Note that it needs to be passed an id from the caller so that it can be linked to corretly with an anchor tag in the body of the main text.

I’m passing in a time variable here to make links unique. You see, if you parse many of these entries on a single HTML page you’ll end up with multiple #footnote1 divs. To make them unique, we’ll pass down a time variable from above to seed them.

  footnote_label = Build.tag("span", Build.tag("sup", id.to_s), :class => "footnote-number")

  Build.tag("div", footnote_label + footnote_content, :id => "footnote#{id}#{time}", :class => "footnote")
end

#html(id, time) ⇒ Object

This is the method that will place the anchor tag and id of the footnote within the paragraph body itself.
