study note for dojo

1."dojo/query" is very important when you want to get elements'attributes from your document, and it's often faster.

2.The codes below are necessary for us to build modular viewer and controller code for mvc applications：

    var dojoConfig = {
        async: true,
        // This code registers the correct location of the "demo"
        // package so we can load Dojo from the CDN whilst still
        // being able to load local modules
        packages: [{
            name: "demo",
            location: location.pathname.replace(/\/[^/]*$/, '') + '/demo'
        }]
    };

• data-dojo-config：取代了原来的dojoConfig，用以配置dojo库的各项参数
• data-dojo-type：取代了原来的dojoType属性，用以指定所用的dojo对象类型
• data-dojo-props：取代了原来所有初始化dojo控件的自定义属性。
