现在使用下面的 javascript，我得到了鼠标指针上的经纬度值。我怎样才能让它像在谷歌地球中一样出现在铯屏幕的底部。

viewer.entities.add({
    id: 'mou',
    label: {
        // position : Cesium.Cartesian2.ZERO, 
        show: true;
    }
});
viewer.scene.canvas.addEventListener('mousemove', function(e) {
    var entity = viewer.entities.getById('mou');
    var ellipsoid = viewer.scene.globe.ellipsoid;
    // Mouse over the globe to see the cartographic position 
    var cartesian = viewer.camera.pickEllipsoid(new Cesium.Cartesian3(e.clientX, e.clientY), ellipsoid);
    if (cartesian) {
        var cartographic = ellipsoid.cartesianToCartographic(cartesian);
        var longitudeString = Cesium.Math.toDegrees(cartographic.longitude).toFixed(10);
        var latitudeString = Cesium.Math.toDegrees(cartographic.latitude).toFixed(10);
        entity.position = cartesian;
        entity.label.show = true;
        entity.label.font_style = 84;
        //entity.position= Cesium.Cartesian2.ZERO; 
        entity.label.text = '(' + longitudeString + ', ' + latitudeString + …
