Is there any way to prevent the default back button behavior in the navigation bar of a navigationview?

I'm trying to use Sencha Touch 2 history and linking abilities with routers, but that requires me to essentially intercept all button taps so that I can update the url.

The back button in a navigation bar creates all kinds of nightmares as far as thats concerned, and I can supply code if someone thinks they have an alternate solution, but preventing the default back button behavior seems best (so as to play nice with browser back button)

如果您想处理后退按钮，您可以使用在导航视图的后退按钮被点击时触发back event的哪个按钮。有关如何操作，请参阅我之前的回答。navigation view

如果您想完全隐藏后退按钮，只需使用：

Ext.select('.x-button-back').hide();

试试这个 Ext.getCmp('navigationview's id').getNavigatorBar().hide()
