使用Prototype将Rel External更改为Target Blank

Posted 2021-02-26

There's been a popular trend to use javascript to add target="_blank" to anchors with rel="external". So in the name of making everything in my site Prototype based I worked out a script to do just that.

<script type="text/javascript">
Event.observe(window, 'load', function() {
    $$('a[rel="external"]').each(function(link){
        if(link.readAttribute('href') != '' && link.readAttribute('href') != '#'){
            link.writeAttribute('target','_blank');
        }
    });
});
</script>
