When your visitors stumble upon your site, they have a toolbar on the top of the page that basically loads your Tumblr Blog through an iframe. If you have links in your post captions, they won’t work unless you have your target set to “_blank”. You are able to do this in the post editor, but this can be cumbersome if you have lots of links, or if you simply forget.
It’s much easier to add a few lines of jQuery to the bottom of your theme that loops through all the post links and dynamically adds the ‘target=”_blank” to all the <a> tags.
<script>
$(“.caption a”).each(function(){
$(this).attr(‘target’,”_blank”);
});
</script>
This is a simple, efficient way to update all your links on page load, that will work seamlessly with the stumble upon toolbar.
