Openlayers 标记移动与地图抓取

我有一个问题，我在地图上单击时定义了一个事件，我在单击的位置移动了我的标记。它可以工作，但当我想通过点击/抓取来移动我的地图时，它也会移动我的标记，听起来很合法，但我不想这样

以下是移动标记的事件代码：

// On créé un nouvel event click afin de déplacer le marker déjà placé sur la map 
map.events.register("click", map , function(e){
    var opx = map.getLayerPxFromViewPortPx(e.xy);
    marker.map = map;
    marker.moveTo(opx);
}

如何在不移动标记的情况下抓取地图并保持在同一水平/水平位置

编辑： 以下是完整的功能代码（如果有帮助）：

function initPageCarto() {
        //niveau de zoom 
        zoom=12;

        var scale= new OpenLayers.Control.ScaleLine({ topInUnits: 'km', bottomInUnits: 'm'});

        // gestion de la carto 
        var options = {

你是说你想让标记保持在相同的像素位置，而不是地理位置？不，我想让它保持在相同的地理位置，但它会移动到我单击以抓取地图的位置。这不是默认行为吗。移动地图时，所有向量都会随之移动。也许我还不明白这个问题。也许您可以发布一个完整的工作示例，JSFIDLE或类似的？这很难解释。我希望我的标记移动到我在地图上单击的位置，但当我想通过左键单击+移动鼠标移动地图时，当我释放左键单击时，它也会将我的标记移动到单击的位置以移动地图，我不希望这样。我会试着发布一个提琴或截图来更好地解释它。那么，当你拖动地图时，你希望标记保持在与地图相同的相对位置吗？
