None of the above worked for me. I am on 4.9.5.

This worked: http://www.dotnetnuke.com/Community/Blogs/tabid/825/EntryId/1949/New-windows-from-your-menu-item.aspx

java script:void(window.open('http://www.site.com'))

but remove the space from javascript

thanks, Will

I know this is a bit of an old thread... but found it useful and hopefully someone who searches later will be able to use this:

hey, if you are like our organization, we have many users who are not going to type that in each time they have to open a link in a new window... they will either forget, type it wrong, etc as they are not techy. For those who want a pretty easy way to do this and have access to your DNN installation... then open up the skin you are usoing ... and at the bottom put this block of code:

<script type="text/javascript">

$(function () {
      $('a:not([href=""])').each(function () {
          if (this.hostname !== location.hostname) {
              $(this).addClass('externalLink').attr('target', "_blank");
          }
      });
});

</script>

what this does is any EXTERNAL link it will add the target="_blank" into any links on your page ... and as well a class called externalLink so you can make a CSS entry and change stuff around. give it a shot...

I am using 5.6.2 and have had success with void(window.open('...')). The issue I am having though is that two new windows open, instead of one.

Please let me know if you have any insight into this.

Thanks so much,
Jenny
