Extjs如何在beforeremove事件中得到tabId

Question

   Extjs如何在beforeremove事件中得到当前将要关闭的tabId，我试过了。事件参数是为TabPanel的对象，而不是将要关闭Tab的对象.我想知道怎么获取

Answer 1

beforeremove : ( Ext.Container this, [color=red]Ext.Component component[/color] )
Fires before any Ext.Component is removed from the container. A handler can return false to cancel the remove.

Listeners will be called with the following arguments:

* this : Ext.Container

[color=red] * component : Ext.Component 这就是你所要的 将要关闭Tab的对象[/color]
The component being removed
