Rails - Aug 2006 - <img onclick> vs link_to_remote()

In one of my view , I have an image the user need to click to close a 
<div>selections</div> added by an Ajax call.

if I use  :
<img src ="/images/icon_closeitem.gif", size="16*16", 
border="0",alt="Close Selection", title="Close",
onclick="<%=
remote_function(:url => { :controller => ''property'',
:action =>
''closeSelection'', :id => @property  }) %>" >

then it''s ok, in my property_controller.rn
  def closeSelection
      render :update do |page|
        page.replace_html ''selections'', ""
      end
  end

will reset the content of the ''selections'' div to empty...
fine

but if I try to use
<%= link_to_remote (image_tag("icon_edititem.gif" ,
:size=>"16*16",
:border=>0, :alt=>"Edit this Property", :Title=>"Edit
this Property") "
, { :controller => "property", :action => "delete",:id
=> @property },
:class => "additem") %>

the href is "#" (the onclikc seems to be generated..) the URL is 
''property/#''  and obviously the controller action is not
performed....

I surely miss an important parameter... which one ?

Hi Kad,

please try:

:url => { :controller => "property", :action =>
"delete",:id => @property }

Cheers,

While this is the correct response, I must say that AJAX is way overkill 
for this.  This task is just simply javascript.  You are makign a 
request to the server that doesn''t change the server state in any way 
and return no useful information.

I think this would be a much better solution:

<%= link_to_function image_tag(...),
    render(:update) {|page| page.replace_html ''selections'',
""}
%>

Still uses RJS, and requires no AJAX call to the sever at all.  Plus it 
will be insatnt rather than a short wait for the server to respond.  Why 
query the server if you don''t need to?

Hi Alex,

you''re absolutely right. I haven''t even took a closer look to
what Kad is
doing exactly but just saw that his typo.

Cheers,
Jan
