当用户单击按钮时，我需要将 WidgetB 添加到 WidgetA (我想使用 WidgetA containerNode )。
我在按钮事件监听器中尝试了以下操作，但没有成功:
var item = registry.byId('wA');
item.containerNode.innerHTML = '<span id="wB" data-dojo-type="WidgetB"></span>'
parser.instantiate(['wB']);
我需要一个工作示例，谢谢。

最佳答案
我能够使用以下代码找到解决方案:
使用:
parser.instantiate() http://jsbin.com/vetizefehe/1/
parser.parser() http://jsbin.com/rupejizizi/1/
基本上，我使用包含 dojo-type 数据属性的新 HTML 修改 DOM 元素 containerNode 到我的自定义小部件 (WigetB)。
在我使用 parse.initiate() 根据新添加的 Widget 选择性地允许 DOJO 解析之后或 parser.parser() 。
我仍然很想知道是否有更好的方法来达到相同的结果，因为我不确定选择性解析是否是最佳选择。
注释:
解析器.解析器() 如果 HTML 包含多个嵌套级别的小部件，也可以很好地工作。 解析器.initiate() 仅适用于 1 级嵌套。
