</div>

Hello,

I have a partial that I would like to allow users to either display or  
not display a partial, by clicking a gif.

I want it so that when they click an “x”, the partial is hidden, and  
the “x” becomes a check mark. Then, when they click the check mark,  
the partial is displayed, and the check mark becomes an “x” again.  
Here is my strategy:

– make a helper that toggles a style=“display: none” inside the div  
that contains my partial, depending on whether show / hide is set to 1  
or 0 in my database for a given user  
– hook up my check marks to a link\_to\_remote action in my controller,  
that toggles show / hide in the database, and does a page.replace\_html  
for my partial

(Code is below)

When I click once on my gif, my partial disappears. When I look at  
the html source, the style=“display: none” is not in the source – I  
have to refresh the entire page to see style=“display: none”

When I click my gif again, my partial does not reappear. When I check  
the source, I can see the partial – but i have to do a page refresh  
in order to see the partial in my browser.

Help very very much appreciated.

Charlie

How would it? your code isn’t replacing content\_box\_5, just the html  
inside it.

I suspect the same is happening. You’ll need stuff to hide/show divs  
in your rjs (Element.hide & Element.show for example).

Ok, that did the trick; I thought the entire div was being replaced,  
not just the html inside it.

All I had to do to make it work was to put the html I wanted replaced  
inside that div, and everything works fine.

Thanks,
