extJS:如何在MVC中动态创建grid.Panel中注册事件?

当我双击动态创建的网格时,我正在尝试打开表单。这对于静态网格来说不是问题,但是当我创建动态网格时,我无法捕获双击事件。

我的导航控制器(创建面板并添加它们的导航控制器)如下所示:

//Housekeeping and helper functions removed
onNavigationSelection: function(view, record, item, index, eventobj, obj) {
    var groupsstore = this.getGroupsStore();

    groupsstore.load({
        callback: this.createPanels,
        params: {},
        scope:this
    });
},
createPanels: function() {
for (var i = 0; i < groupArrayCounter.length; i++) {
        var storeName = 'store' + groupArrayCounter[i];
        var panelName = 'panel' + groupArrayCounter[i];
        var newstore = createStore(storeName, GroupArrays[groupArrayCounter[i]]);
        var panel = createPanel(panelName, newstore);
        this.getGroupPanel().add(panel);
}

    function createStore(name, data) {
        var createstore = Ext.create('Ext.data.ArrayStore', {
            extend: 'Ext.data.ArrayStore',
            requires: 'NG.model.Person',
            model: 'NG.model.Person',
            data: data,
            fields: ['id', 'auc', 'dateAdmitted', 'name', 'cpr', 'department', 'group' , 'active', 'dateBooked', 'dateStart', 'dateEndCalculated', 'dateEndActual', 'comments']
        });

        return createstore;
}

    function createPanel(name, store) {
        var createpanel = Ext.create('Ext.grid.Panel', {
            store: store,
            title: " Muh ",
            alias: 'widget.'+name,
            columns: [
                {header: 'Navn', dataIndex: 'name', flex: 1}
            ]});

        return createpanel;
}

我的ChangePerson控制器(你应该能够双击一个人的那个):

init: function() {
    this.control({
        'activepersons': {
            itemdblclick: this.onActivepersonsClick
        },
        'waitingpersons': {
            itemdblclick: this.onWaitingpersonsClick
        },
        'group': {
            itemdblclick: this.onGroupClick
        },
        //This is what I want, but it does not work
        'panel17': {
            itemdblclick: this.onGroupClick
        },
        //This is what I want, but it does not work
        'panel19': {
            itemdblclick: this.onGroupClick
        }

    });
},
onActivePersonsClick: function(view, record, item, index, eventobj, obj) {
    var view = Ext.widget('personform');
    view.down('form').loadRecord(record);
},
onWaitingPersonsClick: function(view, record, item, index, eventobj, obj) {
    var view = Ext.widget('personform');
    view.down('form').loadRecord(record);
},
// Is never called
onGroupClick: function(view, record, item, index, eventobj, obj) {
    var view = Ext.widget('personform');
    view.down('form').loadRecord(record);
}

从调试中我知道有一个grid.Panel创建了别名panel17和panel19,但是因为稍后添加它们,上面当然不起作用。我想要完成的是将我的ChangePerson控制器中的onGroupClick事件连接到我动态创建的网格,但我不知道如何执行此操作,因为我似乎无法访问导航中的ChangePerson控制器控制器。

致以最诚挚的问候,谢谢你的进步!

this.control将侦听器添加到创建控制器时存在的类。 一个简单的解决方案是使用函数on在创建面板后附加事件,如:

 function createPanel(name, store) {
        var createpanel = Ext.create('Ext.grid.Panel', {
            store: store,
            title: " Muh ",
            alias: 'widget.'+name,
            columns: [
                {header: 'Navn', dataIndex: 'name', flex: 1}
            ]});
        createdPanel.on('itemdblclick', function(view, record, item, index, eventobj, obj) {
                      var view = Ext.widget('personform');
                      view.down('form').loadRecord(record);
                   });
        return createpanel;
}
