将dojo.declare更改为“本机Javascript类声明”

Question

我有这段代码：

dojo.declare("dh.medview.Viewport", null, {
    someMember: null;
    someFunction: function() {
    }
});

如何转换此代码以获得纯粹的“JS类”decleration？

Answer 1

// create namespace
dh = dh || {};
dh.medview = dh.medview || {};

// constructor:
dh.medview.Viewport = function() {
    // yours is empty
};

// setup properties of the prototype
var proto = dh.medview.Viewport.prototype;
proto.someMember = null;
proto.someFunction = function() {…};
