煎茶触摸检查登录之前，每种方法

Question

在sencha touch中，我需要在控制器中的每个操作之前检查用户登录。 配置“方法”不好，因为它要求从路由中调用操作。 但是我习惯从函数this.fireEvent（）调用动作。

更新：

我想在onNewNoteCommand（），onSaveNoteCommand（），onDeleteNoteCommand（）之前调用checkLogin（），但是我不想将checkLogin（）放在这些函数中，因为我必须从许多其他函数中调用checkLogin（）。 我该怎么做？ 谢谢。

Ext.define('note.controller.Note',{
extend:'note.controller.BaseController',
config:{    
    refs:{
        noteListContainer:'notesListContainer',
        noteEditor:'noteEditor'
    },
    control:{
        notesListContainer:{
            newNoteCommand:'onNewNoteCommand',
            editNoteCommand:'onEditNoteCommand',                
            onNodeListDisclose:'onEditNoteCommand'
        },
        noteEditor:{
            saveNoteCommand:'onSaveNoteCommand',
            deleteNoteCommand:'onDeleteNoteCommand',
            homeCommand:'onHomeCommand'
        }
    }
},
checkLogin:function(){
    console.log('CheckLogin function');
},
logHomeCommand:function(action){
    console.log('logHomeCommand');
    action.resume();

},    
onDeleteNoteCommand:function(){
    var noteEditor = this.getNoteEditor();
    var currentNote = noteEditor.getRecord();        
    notesStore = Ext.getStore('Notes');
    notesStore.remove(currentNote);
    notesStore.sync();
    this.activeNotesList();
},
onSaveNoteCommand:function(){
    console.log('onSaveNoteCommand');
    var noteEditor = this.getNoteEditor();
    var currentNote = noteEditor.getRecord();
    var newValues= noteEditor.getValues();
    currentNote.set('title',newValues.title);
    currentNote.set('narrative',newValues.narrative);
    var errors = currentNote.validate();
    console.log(errors);
    if(! errors.isValid()){
        Ext.Msg.alert('Wait!','Please check for error');
        currentNote.reject();
        return;
    }
    notesStore = Ext.getStore('Notes');
    if( null == notesStore.findRecord('id',currentNote.data.id)){
        notesStore.add(currentNote);
    }
    notesStore.sync();
    this.activeNotesList();
},
activeNotesList:function(){
    Ext.Viewport.animateActiveItem(this.getNoteListContainer(),{
        type:'slide',
        direction:'right'
    });
},
activeNoteEditor:function(model){
    var noteEditor = this.getNoteEditor();
    console.log(noteEditor);
    noteEditor.setRecord(model);
    Ext.Viewport.animateActiveItem(noteEditor,{
        type:'slide',
        direction:'left'
    });
},
onNewNoteCommand:function(){
    console.log('onNewNoteCommand');
    var now = new Date();
    var noteId = (now.getTime()).toString() + (this.getRandomInt(0,100)).toString();
    var noteModel = Ext.create('note.model.Note',{
        id:noteId,
        dateCreated:now,
        title:'',
        narrative:''
    });
    this.activeNoteEditor(noteModel);
},
getRandomInt: function (min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
},
onEditNoteCommand:function(list,record){
    console.log('onEditNoteCommand');
    this.activeNoteEditor(record);
},
launch:function(){
    this.callParent(arguments);   
    console.log('launch');
},
init:function(){
    this.callParent(arguments);
    console.log('init');
}
