[jQuery] Re: Change image attribute based on variable

Hi,

instead of doing a complicate string handling you could simply use
window.location.hash:

$finalurl = window.location.hash;

For debugging I would do it step by step and not all in one line:

var el = $($finalurl+" :first");
var src = el.attr("src");
var src_split = src.split(".");
var new_src = src_split.join("_on.");
el.attr("src", new_src);

This way you can use firebug to step through your code and see which
statement produces the error.
