ExtJS查找注册对象的事件处理程序 [英] ExtJS find events handlers registered with an object

问题描述

我想找到哪些事件处理程序在一个对象上注册（在具体情况下，它是TYPO3 CMS后端的pagetree）。

I would like to find which event handlers are registered over an object (in my concrete case it's the pagetree in the TYPO3 CMS backend).

是否有一种方法获取所有事件处理程序？

Is there a method to get all event handlers ?

推荐答案

您可以简单地浏览其事件财产。大多数成员将只是 true ，但实际表示附加事件的成员将是对象。类型如下：

You can simply walk through its events property. Most of the members will be just true, but those actually representing attached events will be objects. Type something like:

var es = Ext.getCmp('my-tree-id').events;
for (var k in es) {
    if (Ext.isObject(es[k])) {
        console.log(es[k]);
    }
}

如果您的对象是Ext.dom.Element，您将检查 Ext.cache ['elementId']。events 。

If your object is a Ext.dom.Element, you would check Ext.cache['elementId'].events instead.
