XenForo Open Specific Domains in a New Tab (XenForo)

[Thirtynader]

Sometimes you may want only certain links to open in a new browser tab, while leaving all other links unchanged.

For example, this is useful if you have:

• A download server on a separate domain
• A URL shortener
• A resume builder or external tools
• Any trusted external service that belongs to your community

The following JavaScript automatically adds target="_blank" only to the domains you specify.

<script>document.addEventListener("DOMContentLoaded", function() { 
// Add the domains that should open in a new tab 
const externalDomains = [     
"example.com",     
"downloads.example.com",     
"tools.example.com",    
 "go.example.com"  
]; 
document.querySelectorAll('a[href^="http"]').forEach(link => {     
try {         
const linkHost = new URL(link.href).hostname.replace('www.', '');         

if (externalDomains.includes(linkHost)) {             
link.setAttribute('target', '_blank');             
link.setAttribute('rel', 'noopener noreferrer');         
}    
 } catch (e) {        
 // Ignore invalid URLs     
} 
});
});
</script>

Customisation​

Simply edit the externalDomains array to include your own domains:

const externalDomains = [
  "example.com",
  "downloads.example.com",
  "tools.example.com",
  "another-domain.com"
];

Installation​

Place the script in any location where custom JavaScript is loaded, such as your XenForo footer template or another global (PAGE_CONTAINER) template that executes JavaScript.

Notes​

• No CSS is required.
• No additional XenForo add-ons are required.
• The script uses rel="noopener noreferrer" for improved security when opening links in a new tab.
• Each subdomain must be added individually if you want it to be included.
