JavaScript pseudo-protocol – Awful! <a href=”javascript:window.open(‘help.html’)”>contextual help</a>

Pointless link – Bad! <a href=”#” onclick=”window.open(‘help.html’); return false;”>contextual help</a>

Using the DOM – Better. <a href=”help.html” onclick=”window.open(this.getAttribute(‘href’)); return false;”>contextual help</a>

No inline JavaScript – Best! <a href=”help.html” class=”help”>contextual help</a>
