History
The first release of JavaScriptMVC was published in May 2008. JavaScriptMVC 2.0 became stable in June 2009 and is based directly on jQuery, mainly to keep the code size small and to focus on its unique features. Version 3.0 was released in December 2010.
Controller
A controller is a list of functions that get called back when the appropriate event happens. The name of the function provides a description of when the function should be called. By naming functions in the correct way, Controller recognizes them as Actions and hook them up in the correct way, for example:
In a controller you can also handle OpenAjax events, for example:
$.Controller.extend('TodosController',{
"main.test subscribe": function(ev, publisherData){
// TODO: do something
},
"other.event subscribe": function(ev, publisherData){
// TODO: do something
}
});
View
JavaScriptMVC uses EJS templates to render HTML data in controllers and inject them into the DOM. The syntax was inspired by ERuby
ERuby
eRuby is a templating system that embeds Ruby into a text document. It is often used to embed Ruby code in an HTML document, similar to ASP, JSP and PHP.-Usage:eRuby allows Ruby code to be embedded within a pair of delimiters...
and is similar to PHP or other server-side template engines.
For example file "test.ejs" ( data = [ "Hello", "World" ] ):
<% for( var i=0, var len = data.length; i < len; i++ ) { %>
<%= data[i] %>
<% } %>
produces the following "output":
Hello
World
Tests
JavaScriptMVC also comes with a comprehensive test plug-in that supports classic unit tests for models, as well as functional test, that are required to deal with event driven architectures. Tests can be run on the command line with Rhino, using Selenium and during development with the integrated test console pop-up window.
