Need a hint for opening every pdf in a new window

hi there,

because i’m new here, in a few words…
i’m managing the websites for two associations working
in the youth welfare. i do this in my free time, on free base…

so now the problem:

because there’s is much info-material in pdf format, i have to get wordpress to open every pdf-link in a new window.

i couldnt find a plugin doing this, only for external links.

with google i found this snippet for jquery

$(“a[href*=.pdf]”).click(function(){
window.open(this.href);
return false;
});

i searched, read and tried for hours – but still don’t get it ??
…cause i’m just a html-css-guy ??

where do i have to put this code to make it work?

tried to put it in /wp-includes/js/jquery/jquery.js – …nothing

tried to put it in a seperate js-file (/my.js) and run the script
with <script src=”/my.js” type=”text/javascript”></script>
from the header.php of the theme. placed it right before the </head>-tag.
– still nothing…

would be nice, if someone can give me some help.

bye,
binxy
