Add support for using hover tips module... not?

Of course. I didn't look at the hover tips module yet, but that is something that of course we would expect from it.

(But good that you brought it up, in case someone reads this and starts doing something.)

I've now had a look at the hovertip module at http://drupal.org/project/hovertip

On a quick glance, it seems it depends on sending invalid html to the browser. The functionality is based on JavaScript that uses custom html element attributes:

This is an example of a <span hovertip=htdef>hovertip</span> (seen in a page that uses hovertip)

As such, I will not integrate this into Footnotes. (It should be noted, that there definitively is a way to implement the exact same hovertip functionality without relying on invalid html. Not to mention that the author even seems to be sloppy with remembering the quotes around attribute values in his own examples...)

Hi Wayland

The example link from hovertip project page http://drupal.org/project/hovertip leads to http://www.dave-cohen.com/node/1186

From there:

<p>The text shown in <span hovertip="italic">italics</span> are examples of <span hovertip="htdef">hovertips</span>.  Move your mouse over the <span hovertip=italic>italic</span> text to see what happens.
<div class=hovertip id=italic>
Text like this appears when you hover.
And disappears after you move your mouse away.
</p>

There are several problems with incorrect html here

1. span element has "hovertip" as attribute name! You cannot invent your own attributes in html.
2. There is a div tag inside a p tag, this is not allowed in html.
3. A minor problem is that some of the attribute values lack quotes (I believe this is what you're asking). That is of course easily fixed by adding the quotes back.

When I had a brief look it seemed like the javascript code in hovertip depends on these erroneous uses of html, so one would have to make some changes to the code to get away from these problems. But it is certainly possible to do the same thing the right way, in case you are interested to try.

Wayland,

for #1, consider using <span class="hovertip"> and then searching for that from javascript. You should be able to get all the same results as now, but with valid html.

Then to get the italics (or whatever formatting you want), use css:

.hovertip {
  font-style: italic;
}

Btw, are you the author of Hovertip?

I'm open to including it, yes.
