Thread: Urgent Help Needed Regardsing Blogspot External Links No-Follow

I have a blog on blogspot and I just wanted to know if I can make all external links No-Follow including Side bar's Friends Links and external links in my Posts? I just post a Java Script to do so but still all my blogs external links are do-follow. following is the java script:

<script type='text/javascript'>
<![CDATA[
jQuery('a').each(function(){var a=jQuery(this).attr('href');if(typeof a!='undefined'&&a!=""&&(a.indexOf('http://')!=-1||a.indexOf('https://')!=-1)&&a.indexOf(window.location.hostname)==-1){jQuery(this).attr("rel","nofollow")}});
]]>
</script>

I need urgent help

Why java, don't you have html option for posts?
