代码：

import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.4
import QuickOSGEarth 1.0

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    Button{
        id: createCylinderManipulatorButton
        text: qsTr("Load")
        z:10
        Component.onCompleted: {
            var keys = Object.keys(createCylinderManipulatorButton);//对象的所有属性
            for(var i = 0; i < keys.length; i++) {
                var key = keys[i];
                // prints all properties, signals, functions from object
                console.log(key + ' : ' + createCylinderManipulatorButton[key]);
                if (key === "x") {
                    createCylinderManipulatorButton[key] = 100;
                }
            }
        }
    }
}

结果：
