The set up is this: Throughout the page I have a certain drop-down  
repeated many times. It is given class=“owner\_column” It’s possible I  
could generate a unique ID for each of these, but it may prove to be  
difficult – although I’ll manage if it turns out to be necessary.

My problem is adding a new “owner” to all of these drop downs  
dynamically. I’ve been experimenting with variations on the  
following:

page.select(‘select.owner\_column’).each do |foo|  
foo.replace\_html ‘blah’  
end

Where “blah” will probably end up being a partial or an explicit  
 statement. But for the time being even inserting the word  
“blah” isn’t working.

This produces an error saying that “replaceHtml” is not a valid  
function. Notice that at some point my “replace\_html” got changed to  
“replaceHtml” (I’m not sure why or how this happened)

Some points to consider:

If instead I do foo.hide all of the select statements disappear as  
expected. This leads me to believe my select statement is accurately  
grabbing the correct objects.

replace\_html takes an id argument. Is it mandatory, if so, what do  
send in its placesince I dynamically grabbed the objects I want to  
modify?

Thanx for your help!!
