Question

我有一个文本字段和一个显示字段。我希望文本字段的用户值显示在显示字段中。我该怎么做？

我的代码如下：

最快的实现将是文本字段上的监听器：

listeners: {
    change: function(field, newValue) {
        field.nextSibling().setValue(newValue)
    }
}

或者您在父容器上使用viewModel并绑定该值，这样可以提高可重用性：

xtype:'panel',
viewModel:{
},
items:[{
    xtype: 'textfield',
    fieldLabel: 'Textfield',
    allowBlank: false,
    bind: {
        value: '{value}'
    }
},{
    xtype: 'displayfield',
    fieldLabel: 'Textfield Value',
    bind: {
        value: '{value}'
    }
}]
