hi. i want do call my js method “appear(box1, box2)” with rails created,  
dynamic ids for my div tags --\>

:complete =\> “appear(’\<%= dom\_id(person.id)box %\>’,’\<%=  
dom\_id(person.id) %\>’)” %\>

…unfortunatly, that doesn’t work: syntax error, unexpected $end,  
expecting ‘)’ and so on.

how has the js call to look like? i hope u r able to help me.  
here s the code snippet:

\<% unless person.about == “” %\>

\<%= link\_to\_remote “mehr”,  
:url=\>{:action =\> “showMore”},  
:update =\> dom\_id(person.id),  
:complete =\> “appear(’\<%= dom\_id(person.id)box %\>’,’\<%=  
dom\_id(person.id) %\>’)” %\>

\<% end %\>

that string is just a string (ie it’s not put through erb)  
“appear(’#{dom\_id(person.id)}box’,’#{dom\_id(person.id)’)”

should do the trick

sorry for disturbing again: now the produced html code is ok, but my  
script isn’t called. i use this script on an other site, thus i’m sure  
the script is ok. can u think about a reason for that problem.

Use firebug to see what’s going on (eg set a breakpoint in your appear  
function).
