I’m trying to get link\_to\_remote to assign a CSS class to the link it  
generates. My code is as follows:

\<%=  
link\_to\_remote “Show Full Info”,  
:update =\> “fullcontact” + reparray.last.to\_s,  
:url =\> “/cm/full\_contact/” + reparray.last.to\_s,  
:classname =\> “contactlink”  
%\>

Which produces this HTML:

Show Full Info

And I would like it to produce this HTML:

Show Full Info

I’ve also tried the code this way:

\<%=  
link\_to\_remote “Show Full Info”,  
{ :update =\> “fullcontact” + reparray.last.to\_s,  
:url =\> “/cm/full\_contact/” + reparray.last.to\_s},  
{ :classname =\> “contactlink” }  
%\>

(The only difference is the addition of the {}'s.) The result is the  
same.  
What am I doing wrong here? I don’t want to statically write the HTML  
into  
the view, which would work fine, but just isn’t as elegant as Ruby on  
Rails  
should be.

Thanks,  
David

Thanks for the help, Daniel. The code you provided produced an error,  
(wrong number of arguments, 4 for 3), but it was your explanation that  
helped me the most. The correct code to do what I was looking for was  
actually:

\<%=  
link\_to\_remote “Show Full Info”,  
{ :update =\> “fullcontact” + reparray.last.to\_s,  
:url =\> “/cm/full\_contact/” + reparray.last.to\_s},  
{ :class =\> “contactlink” }  
%\>

The empty hash you had in the middle of the code was causing the error.  
Thanks for the help, again, Daniel, and I hope this helps anybody else  
who  
has this problem!

If you go to the API page,  
[http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M](http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M)  
000412, you’ll see that the signature for link\_to\_remote is

link\_to\_remote(name, options = {}, html\_options = {})

So, the secong argument is an options hash, and the last is the  
html\_options  
hash - html\_options is where you’d set the class. Your code should look  
like

link\_to\_remote “Show Full Info”,  
{ :update =\> “fullcontact” + reparray.last.to\_s,  
:url =\> “/cm/full\_contact/” + reparray.last.to\_s},

{},  
{ :class =\> “contactlink” }

Also notice that it’s :class, not :classname.

Hope this helps!

Daniel
