Hello there,

I have what I think is a simple problem that I was hoping someone could  
help me with. I have an application that keeps track of many  
restaurants. Each restaurant has many user reviews associated with it.  
When a user does a search it will return a list of restaurants. I would  
like to have a “see reviews” link with each restaurant listing.

Now when someone clicks on the “see reviews” link I would like to have  
the reviews appear instantly below the restaurant listing without a page  
refresh.

Now the way I am doing it is by pre-loading and hiding the reviews. My  
partial for displaying each restaurant looks like this:

\<a href="#" onClick=“toggleReviews()”;\>See Reviews

\<% if !listing.reviews.blank? %\>  
\<%= render :partial =\> ‘review’, :collection =\> listing.reviews %\>  
\<% end %\>

Now the problem is in my toggleReviews function I need the div id of  
the element to toggle. If I use “review” it will show the reviews for  
all restaurants. Any ideas how I can dynamically set the div id to  
something like:

“review” + listing.review.id so that I can toogle the correct one? Or is  
there a better way to accomplish what I am trying to do.

Thanks,  
steve

Assuming each restaurant has a unique ID, I would do the following:

\<a href=“#” onClick=“toggleReviews(‘review\_for\<%= restaurant.id %\>’,  
…)”;\>See Reviews

Thanks for the help - I think were on the right track. I was actually  
trying to use the following:

\<%= link\_to\_function “See Reviews”, “Element.toggle(‘review\_for’)” %\>

but don’t know how to get the restaurant ID in the toggle name. I tried  
this

\<%= link\_to\_function “See Reviews”, “Element.toggle(‘review\_for’ +  
restaurant.id)” %\>

and it didn’t work. Any suggestions?

thanks again,  
steve

Good suggestion Rob! That should work if the DIV id is set accordingly.
