Interlink Hyperlink Modifier

The Interlink Hyperlink Modifier allows websites hosted on multiple top‑level domains (TLDs) to automatically rewrite hyperlinks so they always point to the correct domain. This is ideal for multi‑network environments such as .ca, .com, .us, .cjdns, .ygg, and .akn.

How It Works

Interlink detects the visitor’s current hostname, extracts the domain and TLD, and rewrites any hyperlink marked with the interlink class. This ensures links always point to the correct version of your site — no matter which TLD the visitor is using. 


document.addEventListener("DOMContentLoaded", () => {
    const host = window.location.hostname;
    const parts = host.split(".");
    const detectedTld = parts.pop();
    const domain = parts.join(".");

    document.querySelectorAll(".interlink").forEach(a => {
        const sub = a.dataset.sub;
        const port = a.dataset.port;
        const path = a.dataset.path;
        const overrideTld = a.dataset.tld;

        const tld = overrideTld || detectedTld;

        let url = `http://${sub}.${domain}.${tld}`;

        if (port) {
            url += `:${port}`;
        }

        if (path) {
            url += `/${path.replace(/^\/+/, "")}`;
        }

        a.href = `${url}/`;
    });
});

Using Interlink

Option 1 — External JavaScript File

Add this to your page’s <head>:

<script src="/js/interlink.js"></script>

Option 2 — Inline Script

Place the script directly inside your <head>:


<script>
  // Interlink code goes here
</script>

Inline scripts must be placed in the head so the DOMContentLoaded handler runs correctly.

Attributes

Interlink uses HTML data-* attributes to control link rewriting.

Attribute Description Example
data-sub Subdomain to link to. data-sub="www"
data-port Optional port number for non‑HTTP services. data-port="46631"
data-path Optional folder or file path inside the subdomain. data-path="downloads/game.zip"
data-tld Optional override to force a specific TLD. data-tld="com"
