    <p>I know there is a lot of similar questions are tons of great answers to this. I tried to look at the classical inheritance methods, or those closure methods etc. Somehow I consider they are more or less "hack" methods to me, as it doesn't really what the javascript is designed to do. (Welcome anybody correct me if I am wrong). OK, as long as it works, I satisfy with the classical inheritance pattern like:</p> <pre><code>PARENTClass = function (basevar) { do something here; }; PARENTClass.prototype = { a: b, c: d}; // prototype is auto gen // Inheritance goes here CHILDClass = function (childvar) { do something; }; CHILDClass.prototype = new PARENTClass(*1); // Actual inheritance to the prototype statement // Instance CHILDInstance = new CHILDClass(whatever); </code></pre> <p>Above is somehow, to my understanding the inheritance of JS. But one scenario I have no idea how to implement, is that what if I want to do some initializing DURING object creation (ie, within constructor), and the new object can be used right away.... My illustration on problem might not be too clear, so let me use the following C# Psuedo to explain what I want to do:</p> <pre><code>class PARENT { public PARENT (basevar) { ... } } class CHILD : PARENT { public CHILD (basevar) : PARENT (basevar) // constructor of child, and call parent constructor during construct. { ... } } </code></pre> <p>For some reason (like init. UI elements), putting them in constructor seems the best way to do. Anyone have idea on how can I do it.</p> <p>PS: in the *1, I have no idea what I should put there. PS2: The above situation I DID found the jquery.inherit library can do, I just wonder if not using library can achieve it. PS3: Or my understanding is wrong. Since javascript is not intended to mimick OOP (that's why i call it hack), what is the "CORRECT" logic to implement this.</p>

    2. COUse Object.create() to inherit the prototype from the base class. That way changes to the base class ripple down to the subclass but not the other way around. More details on my blog: http://ncombo.wordpress.com/2013/07/11/javascript-inheritance-done-right/

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.
