Inherit classes

This example shows how to inherit Classes. Every master-class should be defined using ITSA.Classes.createClass(). From that point out, Classes can be inherited by using subClass of the parent-Class.

Code-example:

<body>
    <button id="btnMaster">Print Master values</button>
    <button id="btnSub">Print Sub values</button>
    <button id="btnSubSub">Print SubSub values</button>
    <div id="cont"></div>
</body>

<script src="itsabuild-min.js"></script>
<script>
    var container = document.getElement('#cont'),
        MasterClass, SubClass, SubSubClass, master, sub, subsub;

    MasterClass = ITSA.Classes.createClass(
        function(x) {
            this.x = x;
        },
        {
            printValues: function() {
                container.setHTML('values of MasterClass-instance --> x: '+this.x);
            }
        }
    );

    SubClass = MasterClass.subClass(
        function(x, y) {
            // the constructor automaticly invoke its superclass!
            this.y = y;
        },
        {
            printValues: function() {
                container.setHTML('values of SubClass-instance --> x: '+this.x+', y: '+this.y);
            }
        }
    );

    SubSubClass = SubClass.subClass(
        function(x, y, z) {
            // the constructor automaticly invoke its superclass!
            this.z = z;
        },
        {
            printValues: function() {
                container.setHTML('values of SubSubClass-instance --> x: '+this.x+', y: '+this.y+', z: '+this.z);
            }
        }
    );

    master = new MasterClass(1);
    sub = new SubClass(10, 20);
    subsub = new SubSubClass(100, 200, 300);

    ITSA.Event.after('tap', function(e) {
        master.printValues();
    }, '#btnMaster');

    ITSA.Event.after('tap', function(e) {
        sub.printValues();
    }, '#btnSub');

    ITSA.Event.after('tap', function(e) {
        subsub.printValues();
    }, '#btnSubSub');
