|
* Whisper.View
|
|
*
|
|
* This is the base for most of our views. The Backbone view is extended
|
|
* with some conveniences:
|
|
*
|
|
* 1. Pre-parses all our mustache templates for performance.
|
|
* https://github.com/janl/mustache.js#pre-parsing-and-caching-templates
|
|
*
|
|
* 2. Defines a default definition for render() which allows sub-classes
|
|
* to simply specify a templateName and renderAttributes which are plugged
|
|
* into Mustache.render
|
|
*
|
|
* 3. Makes all the templates available for rendering as partials.
|
|
* https://github.com/janl/mustache.js#partials
|
|
*
|
|
* 4. Provides some common functionality, e.g. confirmation dialog
|
