    <p>This is what I came up with. It has only been tested in Google Chrome.</p> <pre><code>function changeobj() { objs = document.getElementsByTagName('object'); for (i in objs) { for (o in objs[i].children) { if (objs[i].children[o].getAttribute('name') == 'movie') { vidid = objs[i].children[o].getAttribute('value').split('/')[4].split('?')[0]; linkurl = 'http://www.youtube.com/watch?v='+vidid; imgurl = 'http://img.youtube.com/vi/'+vidid+'/default.jpg'; link = document.createElement('a'); link.setAttribute('href',linkurl); link.setAttribute('target','_blank'); img = document.createElement('img'); img.src = imgurl; link.appendChild(img); objs[i].innerHTML = ''; objs[i].appendChild(link); } } } } function changeiframe() { objs = document.getElementsByClassName('youtube-player'); for (i in objs) { console.log(objs[i]); vidid = objs[i].src.split('/')[4].split('?')[0]; linkurl = 'http://www.youtube.com/watch?v='+vidid; imgurl = 'http://img.youtube.com/vi/'+vidid+'/default.jpg'; link = document.createElement('a'); link.setAttribute('href',linkurl); link.setAttribute('target','_blank'); img = document.createElement('img'); img.src = imgurl; link.appendChild(img); objs[i].outerHTML = link.outerHTML; } } window.onload = function () { changeobj(); changeiframe(); } </code></pre> <p>Yes, I know. There is a bug in it. That's why it won't finish. I'm working on it.</p> <p><strong>EDIT:</strong></p> <p>I fixed the original bugs: </p> <pre><code>function changeobj() { objs = document.getElementsByTagName('object'); for (i in objs) { for (o in objs[i].children) { if (objs[i].children[o].getAttribute &amp;&amp; objs[i].children[o].getAttribute('name') == 'movie') { vidid = objs[i].children[o].getAttribute('value').split('/')[4].split('?')[0]; linkurl = 'http://www.youtube.com/watch?v='+vidid; imgurl = 'http://img.youtube.com/vi/'+vidid+'/default.jpg'; link = document.createElement('a'); link.setAttribute('href',linkurl); link.setAttribute('target','_blank'); img = document.createElement('img'); img.src = imgurl; link.appendChild(img); objs[i].innerHTML = ''; objs[i].appendChild(link); } } } } function changeiframe() { objs = document.getElementsByClassName('youtube-player'); for (i in objs) { if (objs[i].src) { vidid = objs[i].src.split('/')[4].split('?')[0]; linkurl = 'http://www.youtube.com/watch?v='+vidid; imgurl = 'http://img.youtube.com/vi/'+vidid+'/default.jpg'; link = document.createElement('a'); link.setAttribute('href',linkurl); link.setAttribute('target','_blank'); img = document.createElement('img'); img.src = imgurl; link.appendChild(img); objs[i].outerHTML = link.outerHTML; } } } window.onload = function () { changeobj(); changeiframe(); } </code></pre> <p>There is another bug that won't load any 4th movie, but I'm sure this should give you enough to make your own version.</p> <p><strong>EDIT:</strong> @evel - If you want to put a play button, you can put something like this into your CSS:</p> <pre><code>.YOUTUBE_VID { background-image: play.png; background-repeat: none; background-postion: center; } </code></pre> <p>And than add it the class to the link:</p> <pre><code>link.className += " .YOUTUBE_VID"; </code></pre> <p><strong>EDIT:</strong> Instead of using the for loop, I'm looping the function. This seems to be working:</p> <pre><code>function changeiframe() { objs = document.getElementsByClassName('youtube-player'); if (!objs[0]){return false;}; if (objs[0]) { vidid = objs[0].src.split('/')[4].split('?')[0]; linkurl = 'http://www.youtube.com/watch?v='+vidid; imgurl = 'http://img.youtube.com/vi/'+vidid+'/default.jpg'; link = document.createElement('a'); link.setAttribute('href',linkurl); link.setAttribute('target','_blank'); img = document.createElement('img'); img.src = imgurl; link.appendChild(img); objs[0].outerHTML = link.outerHTML; } changeiframe(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
