Question

I am using a simple Jquery script to force target="_blank" on all external links. The problem is that it opens up subdomains in new windows. I want to adapt this code so it allows for subdomains in the same browser session versus forcing a new window.

For instance, if my site was on http://pixeltest.com and I had a link to http://test.pixeltest.com, that would open up in a new window.

The Code:

$("a").filter(function() {
    return this.hostname && this.hostname !== location.hostname;
}).attr('target', '_blank');

Any thoughts on how I can do this?

Answer 1

change

return this.hostname && this.hostname !== location.hostname;

to

return this.hostname && this.hostname.substr(this.hostname.indexOf('.')) !== location.hostname.substr(location.hostname.indexOf('.'));

this should only then compare everything after the first dot.
