Rails spinoffs - May 2007 - prototype setStyle (background-image) relative url problem

Hi there,

hope I can explain this one! When I try to use a setStyle call and set
the backgroundImage property of an element, I''m having some problems
using a relative URL.

my directory structure is this:

SERVER_ROOT/context/javascript/tree.js
SERVER_ROOT/context/style/tree/tree.css
SERVER_ROOT/context/images/node_icons/open.png
SERVER_ROOT/context/images/node_icons/closed.png

in my tree.css file i set background image using the relative
url: ../../images/node_icons/open.png

this works fine. However in my tree.js file I use the prototype
setStyle call and use the following:

nodeIconSpan.setStyle({backgroundImage:''url(../images/node_icons/
1nodeopen.gif)''});

this doesn''t work, it appears that the browser attempts to load from
SERVER_ROOT/images/node_icons/1nodeopen.gif

which is wrong (no ''context'').

I thought that maybe the image should be relative to the original css
file but that doesn''t work either. I can get it to work fine using an
absolute url but I''d really rather not do that.

Any ideas??

Many thanks.

Steven Shand

You''re playing with the style DOM property, which means your base URI
is
that of your HTML page.  So you must use URIs relative to the current
HTML page indeed.  Or use absolute.  It''s nominal!

Thanks for that. It seems so obvious now I can''t believe I
didn''t try
that option!

Cheers again
