    <p>I'm trying to wrap my head around using bind/trigger in an inheritance scenario. Here is what I got:</p> <pre><code> var MyApp = {}; MyApp.GrandParent = function (){ var self = Object.create({}), $self = $(self); self.doFoo = function(){ console.log('Just to asure we can call from child to grandparent'); $(this).trigger('Happened'); //$self.trigger('Happened'); //Why doesn't it work this way }; return self; } MyApp.Parent = function(){ var self = Object.create(MyApp.GrandParent()), $self = $(self); self.doSomething = function(){ console.log('Just to asure we can call from child to parent'); $(this).trigger('SomethingHappened'); //$self.trigger('SomethingHappened'); //Why doesn't it work this way }; return self; } MyApp.Child = function(){ var self = Object.create(MyApp.Parent()), $self = $(self); $self.bind('SomethingHappened', function(){ console.log('Client logs: SomethingHappened'); }); $self.bind('Happened', function(){ console.log('Client logs: Happened'); }); return self; } var foo = new MyApp.Child(); foo.doSomething(); foo.doFoo(); </code></pre> <p>Working Example: <a href="http://jsfiddle.net/cburgdorf/8fWta/12/" rel="nofollow">http://jsfiddle.net/cburgdorf/8fWta/12/</a></p> <p>As you can see, we have an inheritance chain starting by the grandparent, over the parent to the child. It works. However, I just don't understand why I can't trigger the events on the $self object. It feels wrong to fire them on $(this).</p> <p>What I want to archieve is to keep the prototype chain working and fire the events on the $self object. I guess I need to use something like $.proxy maybe but I really don't have a clue.</p> <p>I know I could also do it like this <a href="http://jsfiddle.net/cburgdorf/8fWta/11/" rel="nofollow">http://jsfiddle.net/cburgdorf/8fWta/11/</a> but I would rather keep the prototype chain working...</p>

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.
