I need to update a series of html tags with the same content.

I’ve tried running the following in my rjs file:

page.select(".some\_class").each do |item|  
item.replace\_html(“Some Content”)  
end

But it won’t work.

However, when I run:

page.select(".some\_class").each do |item|  
item.hide  
end

it does.

I know part of the problem is that replace\_html needs the element id.  
But how, in RJS, would I do that?

Thanks  
Will

something like page.replace\_html item, ‘some\_content’ might work  
(insude the each block)  
However when you get to the point that you’re fighting rjs you might  
as well just write the raw javascript

Fred, that worked, I was just about to write my own method to handle it  
too.

Thanks!
