Javascript 开放层点事件

有没有人举过一个关于如何使用开放层事件处理程序的例子

谢谢

    function mapCreate(lon,lat){
        map = new OpenLayers.Map("map1");
        var osm = new OpenLayers.Layer.OSM();
        vectors = new OpenLayers.Layer.Vector("Vector Layer");
        map.addLayer(osm);
        var center = new OpenLayers.LonLat(lon,lat).transform(
            new OpenLayers.Projection("EPSG:4326"),
            map.getProjectionObject()
        );

        point = new OpenLayers.Geometry.Point(center.lon,center.lat);
        vectors.addFeatures([new OpenLayers.Feature.Vector(point)]);
        drag = new OpenLayers.Control.DragFeature(vectors);
        //map.addLayer(vectors);
        map.addControl(drag);
        drag.activate();
        map.setCenter(center, 15);
        map.addLayer(vectors);
        point.events.register('moveend',point, function(evt){
            alert('hello');
        });

    }

这是我尝试过的一个例子，由于某些原因，这部分不起作用

point.events.register('moveend',point, function(evt){
                alert('hello');
            });

下面是一些类似的代码，我过去曾使用它们在页面右侧的div列表上悬停显示一个标记。包括它是因为它展示了我过去是如何处理这些问题的。我认为这不是你想要的

/* Included for per-item hovering from the paginated layer. */
function onFeatureSelected(event) {
    hoveredItem = $(this).attr('lookup');

    /* Do something here to indicate the onhover */
    // find the layer pagination id
    var feature = findFeatureById(hoveredItem);

    if (feature) {

        // use the pagination id to find the event, and then trigger the click for that event to show the popup
        // also, pass a null event, since we don't necessarily have one. 
        feature.marker.events.listeners.click[0].func.call(feature, event)
    }
}
function onFeatureUnselected(event) {
    /* Do something here to indicate the onhover */
    // find the layer pagination id
    var feature = findFeatureById(hoveredItem);

    if (feature) {

        // use the pagination id to find the event, and then trigger the click for that event to show the popup
        // also, pass a null event, since we don't necessarily have one. 
        feature.marker.events.listeners.click[0].func.call(feature, event)
    }

    /* Do something here to stop the indication of the onhover */

    hoveredItem = null;
}

function findFeatureById(featureId) {
    for (var key in map.layers) {
        var layer = map.layers[key];
        if (layer.hasOwnProperty('features')) {
            for (var key1 in layer.features) {
                var feature = layer.features[key1];
                if (feature.hasOwnProperty('id') && feature.id == featureId) {
                    return feature;
                }
            }
        }
    }
    return null;
}

如果你想在它被创建的时候把它添加到这一点上，我将不得不重新回忆过去是如何做到的。或者，GIS SE应该会对您有所帮助。

谢谢您的代码更新，我不区分标记和点，您怎么办？标记是人们用来识别给定点的东西，不是吗？我区分这两个点是因为点属于向量，而标记不属于向量。我想。从标记的api来看，有一个事件属性可以解决我的问题。啊，很好，我明白你的意思了。另外，希望你现在能解决这个问题。
