我在ExtJs-in-action中阅读了以下评论 -
'Do not dismiss the destruction portion of a Component’s lifecycle if you plan on developing your own custom
Components. Many developers have gotten into trouble when they’ve ignored this crucial step and have code that
has left artifacts such as data Stores that continuously poll web servers...'
在3.4.x中,我从来没有在我的容器/组件上调用显式的析构函数/ destroy 虽然事情看似很好 - 我很好奇 1.在哪些情况下,实施析构函数变得至关重要 2.在关闭浏览器实例时处理组件破坏的正确约定是什么。
