ExtJs：如何将记录传递给创建的元素？

Question

也许任何人都可以帮我解决我的简单问题：使用itemtap我创建一个模态面板。此模态面板具有文本字段。我想将点击的项目绑定到新面板的文本字段。我在监听器函数中使用'Ext.create ...'来创建面板。如何将记录现在传递到我希望在viewModel中使用它的面板？

注意评论！ :-)

这是我的Main.js，带有一个网格和一个itemtap监听器。这里的记录来自：

Ext.define('QuickApp.view.main.Main', {
    extend: 'Ext.tab.Panel',

    xtype: 'tabpanel',
    items: [{
        title: 'Employee Directory',
        xtype: 'grid',
        iconCls: 'x-fa fa-users',
        listeners: {
            itemtap: function(view, index, item, record) { //record is coming from here
                Ext.create('QuickApp.view.main.Formdialog'); //I want to create the dialog here WITH the record
            }
        },
        store: Ext.create('QuickApp.store.Employee'),
        columns: [{
            text: 'First Name',
            dataIndex: 'firstName',
            flex: 1
        }, {
            text: 'Last Name',
            dataIndex: 'lastName',
            flex: 1
        }, {
            text: 'Phone Number',
            dataIndex: 'phoneNumber',
            flex: 1
        }],
    },{
        title: 'About Sencha',
        iconCls: 'x-fa fa-info-circle'
    }]
});

在我的FormDialog.js中，我想收到并使用该记录：

Ext.define('QuickApp.view.main.Formdialog', {
    extend: 'Ext.form.Panel',

    renderTo: Ext.getBody(),

    xtype: 'formpanel',
    title: 'Update Record',
    floating: true,
    centered: true,
    width:300,
    modal: true,
    draggable: true,

    record: record, //At least here I need the record from before
    viewModel : {
        data: {
            employee: record
        }
    },

    items: [{
        xtype: 'textfield',
        name: 'firstname',
        label: 'First Name'
    }, {
        xtype: 'toolbar',
        docked: 'bottom',
        items: ['->', {
            xtype: 'button',
            text: 'Submit',
            iconCls: 'x-fa fa-check',
            handler: function() {
                this.up('formpanel').destroy();
            }
        }, {
            xtype: 'button',
            text: 'Cancel',
            iconCls: 'x-fa fa-close',
            handler: function() {
                this.up('formpanel').destroy();
            }
        }]
    }]
});

谢谢！

当您像这样创建viewmodel时，您可以直接在Formdialog中传递记录

Ext.create({
    xtype: 'formdialog',
    viewModel: {
        data: {
            employee: record
        }
    }
})

或者您也可以使用ViewModel.set()方法在viewmodel中设置您的记录

form.getViewModel().set('employee', record);

你可以在这里查看工作fiddle。
