Putting the following code in a markdown cell works fine for me:<br><br><script type="text/javascript"><br> show=true;<br> function toggle(){<br> if (show){<br> $('div.input').hide();<br> }else{<br> $('div.input').show();<br> }<br> show = !show<br> }<br></script><br><a href="javascript:toggle()" target="_self">toggle input</a><br><br>Johan                                            </div></body>
