betajs 1.0.245

BetaJS is a general-purpose JavaScript helper module. It contains a variety of helper functions and classes.

Getting Started

You can use the library in the browser, in your NodeJS project and compile it as well.

Browser

    <script src="betajs/dist/betajs.min.js"></script>

NodeJS

    var BetaJS = require('betajs/dist/beta.js');

Compile

    git clone https://github.com/betajs/betajs.git
    npm install
    grunt

Basic Usage

The BetaJS module contains a variety of low-level helper libraries, particularly:

• Asynchronous behaviour and Promises
• Object Orientation
• Event Handling
• Dynamic Lists and Collections
• Dynamic Properties
• Remote Method Invocation
• String Manipulation and Templating
• Binary Search Trees
• Timers and Time
• Iterators
• Uris
• State Machine and Abstract Routing

Properties

    var properties = new BetaJS.Properties.Properties({foobar: "initial value"});

    properties.set("foobar", "second value");

    var value = properties.get("foobar");
    // value === "second value"

    properties.of('change:foobar', function(newValue, oldValue) {
        console.log('The value of foobar has been changed from', oldValue, 'to', newValue);
    });

Object Orientation

  TestClass = BetaJS.Class.extend(null, {

    y: 0,

    fooBar: function (x) {
      console.log("Test Class Instance", "fooBar", x, y);
    }

  }, {

    staticFooBar: function (x) {
      console.log("Test Class", "staticFooBar", x);
    }

  });

  TestClass.staticFooBar(5);
  var first = new TestClass();
  first.y = 1;
  first.foobar(2);
  var second = new TestClass();
  second.y = 3;
  second.foobar(4);

  Test Class  staticFooBar  5
  Test Class Instance  fooBar  2  1
  Test Class Instance  fooBar  4  3

Events

    var events = new BetaJS.Events.Events();

    events.trigger("event_name", event_data1, event_data2);

    events.on("event_name", function (event_arg1, event_arg2) {
        // Do something
    }, function_context);

    events.off("event_name", null, function_context);
