Javascript 有没有办法禁用dojox.mobile.switch？

是否有一种方法可以禁用a，使其可见但变灰且不可点击/不可触摸？我在标准API文档中看不到任何内容

编辑：我应该补充一点，我正在使用Dojo 1.7。

我今天不得不这样做。我扩展了开关模块。对我来说效果很好，但我相信它可以改进

define([
    "dojo/_base/declare",
    "dojox/mobile/Switch"
], function(declare, Switch){
    return declare("my.package.Switch", [Switch], {

        disabled: false,
        events: {},

        disableSwitch: function() {
            //remove events (but hold on to them for later).. there may be a better dojo way of doing this
            this.events._onClick = this._onClick;
            this.events.onClick = this.onClick;
            this.events.onTouchStart = this.onTouchStart;
            this.events.onTouchMove = this.onTouchMove;
            this._onClick = function(){};
            this.onClick = function(){};
            this.onTouchStart = function(){};
            this.onTouchMove = function(){};

            //TODO: better styling to make it look disabled?
            // this.domNode.style.opacity = '0.5';
            this.domNode.style['-webkit-filter'] = 'grayscale(1)';

            this.disabled = true;
        },

        enableSwitch: function() {
            //reattach events
            this._onClick = this.events._onClick;
            this.onClick = this.events.onClick;
            this.onTouchStart = this.events.onTouchStart;
            this.onTouchMove = this.events.onTouchMove;

            // this.domNode.style.opacity = '1';
            this.domNode.style['-webkit-filter'] = 'grayscale(0)';

            this.disabled = false;
        }
    });
});

你能找到解决办法吗？我已经通过改变容器的不透明度解决了灰显的问题，但是我没有看到禁用实际控件的方法
