For quick desktop-&gt;mobile I banged out this bookmarklet to gen a qr code. Caveats: this was a quick hack and probably doesn&#x27;t work on everything. super long urls could be a problem.<p><pre><code>  javascript:(function(){if(document.getElementById){var x=document.body;var o=document.createElement(&#x27;script&#x27;);if(typeof(o)!=&#x27;object&#x27;) o=document.standardCreateElement(&#x27;script&#x27;);o.setAttribute(&#x27;src&#x27;,&#x27;https:&#x2F;&#x2F;qrbookmarklet.googlecode.com&#x2F;svn&#x2F;trunk&#x2F;qr.js&#x27;);o.setAttribute(&#x27;type&#x27;,&#x27;text&#x2F;javascript&#x27;);x.appendChild(o);}})();</code></pre>
