Hi guys,
I was wondering if you are able to have a link_to_remote, having an
image_tag and the link_to_remote has a mouseover event that updates a
div. Does the image_tag need the mouseover event? I currently have:
<%= link_to_remote(image_tag(@p_image.public_filename(:thumb)), :update
=> "big_pic", :onmouseover => {:action => :color_change, :id
=>
@p_image.id})%>
I get this error on loading my page:
You have a nil object when you didn''t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
I also have this in attempts to solve my problem :
<%=image_tag @p_image.public_filename(:thumb), :mouseover=>
remote_function(:update => "big_pic", :url => {:action =>
:color_change,
:id => @p_image.id})%>
The page loads but I get an error using firefox, missing ; before
statement. Here is the html that is generated:
<img src="/system/0000/0022/yellow_thumb.gif?1211334531"
onmouseover="this.src=''/images/new
Ajax.Updater(''big_pic'',
''/store/color_change/22'', {asynchronous:true,
evalScripts:true})''"
onmouseout="this.src=''/system/0000/0022/yellow_thumb.gif?1211334531''"
alt="Yellow_thumb"/>
I just want to have an image that fires a mouseover event that updates a
larger image. Is there a better way? I hope someone can help me this.

Re: link_to_remote, image_tag, mouseover is this possible?
You could try something like:
<div class="buttons-get-started">
<%= link_to(image_tag("/images/
get_started_normal.png", :mouseover => ''/images/
get_started_hover.png''), { :controller => ''user'',
:action =>
''register'' }) %>
</div>
