我通过在历史上下文类中使用 Ext.util.History 类解决了这个问题,该类可以在哈希更改时引发事件:
Ext.define('myApp.context.HistoryContext', {
mixins: {
observable: 'Ext.util.Observable'
},
constructor: function(config) {
var me = this;
if (config == null) {
config = {};
}
this.initConfig(config);
Ext.util.History.add('home');
//init Ext.util.History; if there is a hash in the url,
//controller will fire the event
Ext.util.History.init(function(){
var hash = document.location.hash;
me.fireEvent('tokenChange', hash.replace('#', ''));
});
//add change handler for Ext.util.History; when a change in the token occurs,
//this will fire controller's event to load the appropriate content
Ext.util.History.on('change', function(token){
me.fireEvent('tokenChange', token);
});
this.mixins.observable.constructor.call(this);
this.addEvents('tokenChange');
return this.callParent(arguments);
}
});
然后您可以将此上下文注入您的控制器,并观察令牌更改,并在调度方法中实现操作:
Ext.define('myApp.controller.HomeController', {
extend: 'Deft.mvc.ViewController',
inject: [
'historyContext'
],
control: {
appContainer: {},
home: {
click: 'addHistory'
},
about: {
click: 'addHistory'
}
},
observe: {
historyContext: {
tokenChange: "dispatch"
}
},
init: function() {
return this.callParent(arguments);
},
switchView: function(view) {
//change this to get the cards for your card layout
this.getAppContainer().add(Ext.ComponentMgr.create({
xtype : view,
flex : 1
}));
},
addHistory: function(btn) {
var token = btn.itemId;
Ext.util.History.add(token);
},
dispatch: function(token) {
// switch on token to determine which content to load
switch(token) {
case 'home':
this.switchView('view-home-Index');
break;
case 'about':
this.switchView('view-about-Index');
break;
default:
break;
}
}
});
这对于一级路由(#home、#about)应该没问题,但是您需要实现自己的机制来获取二级和三级路由的令牌。(#home:tab1:subtab1) 您可以创建一个服务类来处理获取哈希并将服务注入每个控制器以进行调度。
