If either is true, the key control, shift, or meta (Apple's command) key is being held and you should allow the default link action to proceed. Otherwise, you use <code>preventDefault</code> to stop the link action and handle it with javascript instead.</p> <p>Add <code>target="_blank"</code> to your anchor markup, so the default link behavior is opening a new tab. Otherwise it will open on top of the current page (that may be desired).</p> <p>Here's the javascript, either way:</p> <pre><code>document.getElementById("mylink").onclick = function(evnt) { if ( evnt.ctrlKey || evnt.shiftKey || evnt.metaKey || // apple (evnt.button && evnt.button == 1) // middle click, >IE9 + everyone else ){ return; } evnt.preventDefault(); alert("clicked"); return false; } </code></pre> <p>Fiddle: <a href="http://jsfiddle.net/6byrt0wu/">http://jsfiddle.net/6byrt0wu/</a></p> <p><strong>Documentation</strong></p> <ul> <li>MDN Events - <a href="https://developer.mozilla.org/en-US/docs/Web/API/Event">https://developer.mozilla.org/en-US/docs/Web/API/Event</a></li> <li><code>Event.ctrlKey</code> - <a href="https://developer.mozilla.org/en-US/docs/Web/API/event.ctrlKey">https://developer.mozilla.org/en-US/docs/Web/API/event.ctrlKey</a></li> <li><code>Event.shiftKey</code> - <a href="https://developer.mozilla.org/en-US/docs/Web/API/event.shiftKey">https://developer.mozilla.org/en-US/docs/Web/API/event.shiftKey</a></li> <li><code>Event.metaKey</code> - <a href="https://developer.mozilla.org/en-US/docs/Web/API/event.metaKey">https://developer.mozilla.org/en-US/docs/Web/API/event.metaKey</a></li> <li><code>a</code> tag - <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a">https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a</a></li> </ul>
