    <p>You prototype a method so you never have to do this irritating task again:</p> <pre><code>Date.prototype.toFormattedString = function (f) { var nm = this.getMonthName(); var nd = this.getDayName(); f = f.replace(/yyyy/g, this.getFullYear()); f = f.replace(/yy/g, String(this.getFullYear()).substr(2,2)); f = f.replace(/MMM/g, nm.substr(0,3).toUpperCase()); f = f.replace(/Mmm/g, nm.substr(0,3)); f = f.replace(/MM\*/g, nm.toUpperCase()); f = f.replace(/Mm\*/g, nm); f = f.replace(/mm/g, String(this.getMonth()+1).padLeft('0',2)); f = f.replace(/DDD/g, nd.substr(0,3).toUpperCase()); f = f.replace(/Ddd/g, nd.substr(0,3)); f = f.replace(/DD\*/g, nd.toUpperCase()); f = f.replace(/Dd\*/g, nd); f = f.replace(/dd/g, String(this.getDate()).padLeft('0',2)); f = f.replace(/d\*/g, this.getDate()); return f; }; </code></pre> <p><em>(and yes you could chain those replaces, but it's not here for readability before anyone asks)</em></p> <hr> <p>As requested, additional prototypes to support the above snippet.</p> <pre><code>Date.prototype.getMonthName = function () { return this.toLocaleString().replace(/[^a-z]/gi,''); }; //n.b. this is sooo not i18n safe :) Date.prototype.getDayName = function () { switch(this.getDay()) { case 0: return 'Sunday'; case 1: return 'Monday'; case 2: return 'Tuesday'; case 3: return 'Wednesday'; case 4: return 'Thursday'; case 5: return 'Friday'; case 6: return 'Saturday'; } }; String.prototype.padLeft = function (value, size) { var x = this; while (x.length &lt; size) {x = value + x;} return x; }; </code></pre> <p>and usage example:</p> <pre><code>alert((new Date()).toFormattedString('dd Mmm, yyyy')); </code></pre>

    2. COThis code depends on having prototypes for Date.getMonthName(), Date.getDayName(), and String.padLeft(). This snippet may be more useful to people if you also provided those implementations.

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.

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