This code below will display “Search Friends” in the text box IF  
{:select =\> ‘friend’} is not there and the ajax call also does not  
work. Any ideas how to get the text and to disaply and have the ajax  
call work?

\<%= text\_field\_with\_auto\_complete :friend, :name,{:select =\>  
‘friend’}, :value =\> “Search Friends”, :onfocus =\> “if (this.value ==  
‘Search Friends’) {this.value = ‘’;}”,:onblur =\> “if (this.value ==  
‘’) {this.value = ‘Search Friends’;}”,  
:after\_update\_element =\> “function(element,value){” +  
remote\_function(:url =\> { :controller =\> ‘followerranking’, :action  
=\> :ajax\_add\_friend },  
:with =\> “‘friend[name]=’ + element.value”) + “}” %\>

What do you mean by “not work”? Check your rails log and see if a  
request is hitting your app at all.

Did you include something like \<%= javascript\_include\_tag :defaults %\>  
in your layout or view?

No.  
If the “select” statement is in there the ajax :after\_update works with  
the  
:value=\>"". If it is not then the text displays in the text box for  
:value=\>"", but the  
:after\_update does not work.
