Sample text

Finally, we just replace the view's present address DOM element with the latest one. The same functionality can be achieved with a subview or child view as well, and this would be a better solution indeed. However, there can be situations when creating a new subview for such a small change is redundant and the previous solution might pay off. In the following section, we will understand the real scenarios in which (and how) we should use a subview. Understanding nested views A nested view or subview is basically a child view.

The event listeners are now subview-specific and the subview methods can directly access the model attached to it. This makes the application flow cleaner and also eliminates the extra time that, though small, is required to look up the collection for a particular model through its ID. If your view has multiple similar child items, and each child item needs its own set of events, subviews are the right approach. In the final section of this chapter, we will look at an awesome library, MarionetteJS, which provides some useful readymade BackboneJS extensions.

Nested views or subviews simplify event-handling and layout management to a great extent. We will explore the following topics: °° When we need to use subviews °° How to initialize and render nested views Working with Views °° How to avoid DOM reflow in the case of a large collection of nested views and a complex view DOM structure °° How to clean up resources (child views, events) when you delete a parent view • Templates: Templates are an essential part of Backbone and are used in combination with views to create reusable copies of HTML markup.
