How to move from one view to another view using vi

问题:

In my application I have a one view with topbar and some fields. In this button when I am click the login button I want to move to another view (Dashboard) which is a tabview. So for this I am using viewport. But I am unable to move from one view to another. Here is my code:

app.js

Ext.Loader.setConfig({
    enabled : true
});

Ext.application({
    views : ['TitlePanel', 'dashboardpanel'],
    models : [ 'MyModel', 'wishlistmodel' ],
    stores : [ 'name', 'wishlistsummarystore' ],
    name : 'MyApp',
    controllers : [ 'MyController' ],

    launch : function() {

        var Login = {
                xtype: 'login'
        }
        var Dashboard = {
                xtype: 'dashboard'
        }
        Ext.Viewport.add([Login, Dashboard]);
    }

});

Titlepanel.js

   Ext.define('MyApp.view.TitlePanel', {
extend: 'Ext.Panel',
alias: 'widget.login',
    config: {
        ui: 'light',
        items: [
            {
                xtype: 'panel',
                id: 'LoginScreen',
                items: [
                    {
                        xtype: 'image',
                        docked: 'left',
                        height: 130,
                        id: 'Logoimage',
                        ui: '',
                        width: 170,
                        src: 'app/images/logo.png'
                    },
                    {
                        xtype: 'titlebar',
                        cls: 'mytitlebar',
                        docked: 'top',
                        height: 100,
                        ui: 'blue',
                        items: [
                            {
                                xtype: 'label',
                                height: 36,
                                html: 'Teritree Business Portal',

Hey i am able to solve this problem finally. Because iwas giving wrong references in controller..here is the controller code:

Ext.define('MyApp.controller.MyController', {
extend : 'Ext.app.Controller',
config : {
    refs : {
        TitlePanel : 'login',
        dashboardpanel : 'dashboard'
    },

    views : [
             'TitlePanel',
             'dashboardpanel'
         ],

    control : {
        "#LoginBtn" : {
            tap : 'onLoginButtonTap'
        }
    }
},

slideLeftTransition: { type: 'slide', direction: 'left' },

onLoginButtonTap : function(button, e, options) {

    Ext.Viewport.setActiveItem(this.getDashboardpanel(), this.slideLeftTransition);
}

});

回答2:

Ext.Viewport.setActiveItem(1);

PS: Please notice the viewport case.

Hey @Arindam just put into your MyController file like this,

Ext.define('myapp.controller.MyController', {
    extend : 'Ext.app.Controller',

    config : {
       refs : {
           LoginScreen: '#Login',
           dashboardscreen : '#Dashboard'
       },

       control : {
            "#LoginBtn": {
                tap : 'onLoginButtonTap'
            }
       }
    },

    onLoginButtonTap: function(button, e, options) {
         Ext.getCmp('dashboardpanel').show('slide', true)
         Ext.getCmp('loginpanel').hide()
    }
});

And you have some bugs into dashboardpanel.js file.

I hope this helps :)

I would suggest you to use Ext.navigation.View for this. You can just add viewport in app.js, then in viewport add navigation view, on that navigation view you can push you TitlePanel, and then form button click in the TitlePanel, just push your dashboardpanel.
