JavaScript Write State mode

Writes the toggle of the state mode, as well as the branch loop. But how to implement sub-state nesting it?

/** * by Jackchen 2016-3-26 11.51.20 * * State mode: * One state to another transition. In fact, the program can be transformed into a complex process of extraction out. * For example, the transformation of state in Level2 is complex and can be completely and externally processed. * By specifying the condition of the toggle state in the state object. Reads the current run condition decision. * While the core class can only manage what they need to do, no external switch *////////////////////////////State class//design your own state name, switch state by name to find var Stateitem = function ( Name) {this._name = name;} Stateitem.prototype = {};        StateItem.prototype.construct = stateitem;//updates its coordinates simultaneously, synchronizes to the external element object.defineproperties (Stateitem.prototype, {Name: {        Get:function () {return this._name;        }, Set:function (v) {this._name = v; }});//The Run function, equivalent to the interface, used to run the current state of the code.
