javascript - dojo 中 this.own() 方法的使用

Question

我想知道 dojo 小部件中“this.own()”方法的意图。 Dojo Api 1.8 文档中提到了此方法，例如在 diijit/form/button 下。我在谷歌上没有找到任何对我有意义的东西。这就是提到该方法的方式:

connect(obj, event, method)

Deprecated, will be removed in 2.0, use this.own(on(...)) or this.own(aspect.after(...)) instead.

Answer 1

own函数定义在 dijit/Destroyable ，它是 dijit/_WidgetBase 的基数因此大多数小部件。

dijit/Destroyable is used to track handles of an instance, and then destroy them when the instance is destroyed. The application must call destroy() on the instance in order to release the handles
