</div>

using link\_to\_remote I can do the following :

\<%= link\_to\_remote “Localisation GoogleMap”, :url =\> {:controller =\>  
‘profils’, :action =\> ‘locate\_me’, :id =\> current\_user}, :with =\>  
“‘lat=’+encodeURIComponent($F(‘latitude’))+’&lng=’+encodeURIComponent($F(‘longitude’))”,  
:method =\> :get %\>

where latitude and longitude are hidden fields in my form.

but I must use a link\_to (to display the map), and I don’t know how to  
rewrite that

\<%= link\_to “Localisation GoogleMap”, :controller =\> ‘profils’, :action  
=\> ‘locate\_me’, :id =\> current\_user, :lat =\> ???, , :lng =\> ???

thanks for your help

This a possible approach:

\<%= link\_to(  
name,  
options,  
:onclick =\> “this.href += ‘?lat=’ + encodeURIComponent($F  
(‘latitude’))”  
)  
%\>
