    <p>I have a class-like function</p> <pre><code>var myapp = function() { this.method = function() { //Do something... } } </code></pre> <p>To reference <code>myapp</code> from within methods, the first line in the <code>myapp</code> function is</p> <pre><code>var self = this; </code></pre> <p>So a method in <code>myapp</code> can reference the "class" safely</p> <pre><code>this.anothermethod = function() { self.method(); } </code></pre> <p>The full code:</p> <pre><code>var myapp = function() { var self = this; this.dosomething = function(Callback) { Callback(); } this.anothermethod = function() { //Pass a callback ("self" is required here)... this.dosomething(function() { self.complete(); )}; } this.complete = function() { console.log('All done!'); } } </code></pre> <p><strong>My question is</strong>: can I assign <code>var self = this;</code> from <em>outside</em> the declaration of <code>myapp</code>? I don't want to set <code>self</code> every single time I write a "class".</p> <p>Kind of like this:</p> <pre><code>var library = function() { this.loadclass = function(Name) { var tempclass = window[Name]; library[Name] = new tempclass(); library[Name].self = library[Name]; } } var myapp = new library(); myapp.loadclass('myapp'); myapp.myapp.dosomething(); </code></pre> <p>It doesn't work as expected. <code>self</code> equals <code>window</code> for some reason.</p> <p>I know it's a little abnormal programming, but can it be done?</p> <hr> <p>Note about using <code>self</code>: I remember why I started using it. I wanted to reference the base class (<code>this</code>) from within callbacks inside methods. As soon as you try to use <code>this</code> within a function within a method, it then references the method, not the base class.</p>

    1. COWhy are you assigning methods on `this` in the constructor instead of setting them on the prototype?

    3. CONot even necessary. It depends on how `anothermethod` is called. If called as `myapp_instance.anothermethod();` then you can omit the whole `self` stuff.

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.
