I''m having a hard time figuring out how to handle mouseover events w/ Ruby on Rails (esp. whether Javascript takes over, or the Controller should be used). I''m currently trying to create a simple mouseover info box showing the definition, and some other information, when certain words are moused-over. Say I have an array of Word objects that have 1) word name 2) definition 3) latin origin.>From my controller, I create a list of words by rendering partial (tothe div element "word_list") the collection (using a _word.rhtml partial) In the _word.rhtml partial: How do I set up a trigger for the onmouse over using link_to (assuming that''s the best func to use)? How do I get the Word object definition, etc. into the (currently hidden) info box when someone does mouseover? Is it best done through the controller or though a call to a Javascript function? Finally, where is the positioning of the info box set? (so it appears next to the word it is defining) I hope this is clear enough and thank you so very much in advance! -- Posted via http://www.ruby-forum.com/.

But the data (the definition, or whatever) can come from the server (Rails) if you want it to - that''s up to you. I think the approach I''d take for something like this, would be to load up a bunch of divs: <div id="definition_word1" class="definition"><blah></div> <div id="definition_word2" class="definition"><blah></div> Set up your stylesheet to hide these divs, then use a onmouseover event to turn the on and position them. -- Joshua -------------- next part -------------- An HTML attachment was scrubbed...

My solution to this would be to wrap the relevant words in a
''content_tag'' call
<%= content_tag(''span'',''word'',
"title"=>"definition") %>
This should result in a tooltip with the definition on most browsers.
