Thanks for the help. Your explanation helped a lot, Brian. I did eliminate the parens, which eliminated the browser being hung, but it's still not doing what I want.
I've put the whole script below. It acts on the page https://blogs.secondlife.com/main-threads.jspa (if you go there, you should collapse the upper box, which is called "Channels" or "Communities", depending on your language setting). The page is a list of thread titles on a not-very-functional web forum. What my script does it to fetch the first post in each thread and stick it into a hover tip for each thread link. That much works fine, but only on the first page of links. What happens is that if someone goes to the next page, or any other page, they click on one of the links in this block: <!-- BEGIN pagination--> <span class="jive-pagination"> <span class="jive-pagination-numbers"> <a href="#" onclick="jiveviewthreads.setStart(0); return false;" class="jive-pagination-current" >1</a> <a href="#" onclick="jiveviewthreads.setStart(30); return false;" >2</a> </span> <span class="jive-pagination-prevnext"> <span class="jive-pagination-prev- none">Previous</span> <a href="#" onclick="jiveviewthreads.setStart(30); return false;" class="jive- pagination-next">Next</a> </span> </span> <!-- END pagination --> and then the page is rewritten. What I need is a way to run my script again at this point so that all the hovertips will be inserted. You can see below that I tried to add the click listener to the spans that enclose the pagination links. I put a "console.log" call in that loop so I can see in Firebug whether it's finding the spans. It does, and I see those messages when I call the second and third page, but then they stop. And still, I only get the hover tips on the very first page. I don't see any errors in the Error Console.
