    <p>The <code>element</code> in the script is the id of the tag you pass to the function.<br> So <code>countdown('div1')</code> will show a timer in a tag with id="div1"</p> <p>However your particular timer does not allow multiple instances and uses a global var called interval. </p> <p>Generate the JSON on the server and the rest takes care of itself</p> <p>HERE is an OO version that is more precise since it is only calculating the end time instead of relying on interval which will block if the browser is busy: <a href="http://jsbin.com/ujuzo5/edit" rel="nofollow noreferrer">http://jsbin.com/ujuzo5/edit</a></p> <p>And here is my original solution with the help of the good folks at SO here: <a href="https://stackoverflow.com/questions/4584845/broken-closure-please-help-me-fix-it">Broken closure - please help me fix it</a></p> <pre><code>&lt;script type="text/javascript"&gt; // generate this on the server and note there is no comma after the last item var counters = { "shoes":{"id":"shoe1","minutes":1,"seconds":5}, "trousers":{"id":"trouser1","minutes":10,"seconds":0} }; var intervals = {}; window.onload = function() { for (var el in counters) { countdown(counters[el]) }; } function countdown(element) { var minutes = element.minutes; var seconds = element.seconds; intervals[element.id] = setInterval(function() { var el = document.getElementById(element.id); if(seconds == 0) { if(minutes == 0) { el.innerHTML = "countdown's over!"; clearInterval(intervals[element.id]); return; } else { minutes--; seconds = 60; } } if(minutes &gt; 0) { var minute_text = minutes + (minutes &gt; 1 ?

    2. COThat is what this code is needed for: `var counters = { "shoes":{"id":"shoe1","minutes":1,"seconds":5}, "trousers":{"id":"trouser1","minutes":10,"seconds":0} };` You just generate that on the server

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).
