extjs - 如何从sencha touch中的导航堆栈中删除特定 View ？

Question

我正在插入这样的观点 this.up('navView').push({xtype: 'myView'})
如何删除位于导航堆栈中间的特定 View ？

至少我应该摆脱这个警告

[WARN][Ext.Component#constructor] Registering a component with a id (listxyz) which has already been used. Please ensure the existing component has been destroyed (Ext.Component#destroy().

Answer 1

在推送 View 检查天气之前， View 已经存在，如果它已经存在，则将其销毁，因此您不会收到这些警告并且可以轻松导航。

if(Ext.getCmp('myView')){
                Ext.getCmp('myView').destroy();
}

//Push myView

where  myView should be the id of that view declared in config of that view


    config: {

        id:'myView',

    }
