视图控制器将处于活动状态,但它将控制许多其他视图的一个子视图,因此我认为还有其他主动视图控制器。
The view controller will be active, but it will be controlling one sub-view of many other views, so I think there will be other active view controllers.
基本上,该表单由完全不同的调度程序创建,组件和处理程序等,视图控制器和表单之间没有直接的连接。
By on-the-fly basically the form is created by a completely different dispatcher, with components and handlers, etc. with no direct connection between the view controller and the form.
视图控制器有几个功能,我需要从以下内容获取结果:
The view controller has several functions I need to get results from:
canContinue: function (arg1) {var result = true; /*...*/ return result;} getStatus: function (arg1, arg2) {var result = 0; /* ... */ return result;}/ * .. 。* / 表示代码省略。所以我想访问视图控制器和这些功能。以下这些线条:
/*...*/ means code omitted. So I want access to the view controller and these functions. Something along these lines:
var controller = /* how to get it? */; if (!controller.canContinue(p)) alert(controller.status(q, r));我看到不建议以这种方式直接访问函数,所以尝试触发事件,但我似乎没有得到结果,我需要。
I read it is not recommended to access functions directly in this manner, so tried firing events, but I can't seem to get results back, which I need.
我以为我可以给视图控制器一个 itemId ,然后执行 Ext.ComponentQuery.query('#itemId'),但它似乎不起作用。我想一个视图控制器不是一个组件,是有道理的。
I thought I could give the view controller an itemId, and do Ext.ComponentQuery.query('#itemId'), but it doesn't seem to work. I guess a view controller isn't a component, makes sense.
视图控制器有一个唯一的类和别名,只有一个这些视图控制器有效一时间,如果这有帮助。
The view controller has a unique class and alias, and there will be only one of these view controllers active at a time, if that helps.
我可能错过了一些非常简单的事情。欢迎任何帮助。
I'm probably missing something really easy. Any assistance would be welcome.
推荐答案我不太确定你的问题。这是我的理解:你有不同的看法,他们之间没有直接的关系。但是你想要达到对方视图的控制器。如果是,请检查这个小提琴: fiddle.sencha/#fiddle/urg
I am not quite sure about your question. Here is what I understand: You have different views and there is no direct relation between them. But you want to reach each other view's controller. If so, please check this fiddle: fiddle.sencha/#fiddle/urg
否则,我宁愿准备一个小提琴,显示你的问题。
Otherwise, I'd prefer you prepare a fiddle, which show your problem.
Ext.define('FirstPanel', { extend: 'Ext.panel.Panel', controller: 'FirstPanelController', layout: 'fit', itemId: 'firstPanel', items: [{ xtype: 'button', text: 'FirstPanel Button', handler: 'FirstButtonClick' }] }); Ext.define('FirstPanelController', { extend: 'Ext.app.ViewController', alias: 'controller.FirstPanelController', FirstButtonClick: function(button) { var me = this; var SecondPanelController = me.getView().mainView.down('#secondPanel').getController(); SecondPanelController.FirstButtonClick(); console.log('FirstButton Click'); }, SecondButtonClick: function() { alert('You are in FirstPanelController'); }, init: function() { var me = this; } }); Ext.define('SecondPanelController', { extend: 'Ext.app.ViewController', alias: 'controller.SecondPanelController', SecondButtonClick: function(button) { var me = this; var FirstPanelController = me.getView().up().down('#firstPanel').getController(); FirstPanelController.SecondButtonClick(); console.log('SecondPanelController'); }, FirstButtonClick: function() { alert('You are in SecondPanelController'); }, init: function() { var me = this; } }); Ext.define('SecondPanel', { extend: 'Ext.panel.Panel', controller: 'SecondPanelController', layout: 'fit', itemId: 'secondPanel', items: [{ xtype: 'button', text: 'SecondPanel Button', handler: 'SecondButtonClick' }] }); Ext.define('MainPanel', { extend: 'Ext.panel.Panel', initComponent: function() { var me = this; me.items = [ Ext.create('FirstPanel', { mainView: me }), Ext.create('SecondPanel') ] me.callParent(); } });更多推荐
从FormController中访问功能,即可快速创建
