推荐答案
您可以使用Ext.navigation.View来实现。下面是一个非常简单的应用程序,演示了这一点:
Ext.setup({
// onReady is when we can start building our application
onReady: function() {
// Create the view by just adding a config block into Ext.Viewport.
// We give it a reference of `view` so we can use it later
var view = Ext.Viewport.add({
// Give it an xtype of `navigationview` so it knows to create a NavigaitonView
xtype: 'navigationview',
// Define the list as its only item
items: [
{
xtype: 'list',
// Give it a title so the navigation view will show it
title: 'List',
// `itemTpl` is the template for each item in the list. We are going to create a store
// with a bunch of records, which each have a field called `name`, so we use that in our
// template
itemTpl: '{name}',
// Define our store
store: {
// Define the fields that our store will have
fields: ['name'],
// And give it some data for each record.
data: [
{ name: 'one' },
{ name: 'two' },
{ name: 'three' }
]
},
// Now we add a listener for the `itemtap` event, which is fired when a user taps on an item
// in this list. This event is passed various arguments in the signature, but we only need the
// record
listeners: {
itemtap: function(list, index, target, record) {
// now we have the record from the store, which was tapped. we now want to push a new view into
// the navigaitonview
view.push({
// Give it an xtype of panel
xtype: 'panel',
// Set the title to the name field of the record
title: record.get('name'),
// And add some random html
html: 'This is my pushed view!'
})
}
}
}
]
});
}
});
