javascript - OpenLayers 弹出窗口不响应事件

Question

我有一个带有标记的 OpenLayers map 和一个当我点击标记时应该出现的弹出窗口。这在 IE8 中工作正常，但在 Firefox 3.6 中不工作。任何想法为什么？据我所知，mousedown 事件没有被触发，因为我的日志消息没有出现。 map 在http://ndinfo.heroku.com/test.html我用来创建标记和弹出窗口的代码是:

function addMarker() {
    var map = g_waze_map.map;

    var markers1 = new OpenLayers.Layer.Markers( "Markers1" );
    g_waze_map.map.addLayer(markers1);
    var size = new OpenLayers.Size(21,25);
    var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
    var icon = new OpenLayers.Icon('http://www.openlayers.org/dev/img/marker.png',size,offset);
    var marker = new OpenLayers.Marker(new OpenLayers.LonLat(34.7934759272249, 32.0835554760902),icon);

 markers1.addMarker(marker);
            marker.events.register('mousedown', marker, function(evt) {
                    console.log('hi');
                    var popup = new OpenLayers.Popup.FramedCloud(null,
                                       marker.lonlat,
                                       null,
                                       "<div style='background-color:red; width:150;height:100'>hi</div>",

 null,true,null);

                    map.addPopup(popup);

                    OpenLayers.Event.stop(evt);

                });
}

来自 here 的回答.关键是覆盖 OpenLayers.Control.ModifyFeature 中的 activate() 函数。我没有意识到在创建标记之前拥有控件会以任何方式影响标记，但事实证明确实如此。

var shapes = new OpenLayers.Layer.Vector( "Shapes" );
map.addLayer(shapes);
var modifyControl =  new OpenLayers.Control.ModifyFeature(shapes, {
        activate: function() {
            var activated = false;
            if(OpenLayers.Handler.prototype.activate.apply(this, arguments)) {

                this.map.events.on({
                    "removelayer": this.handleMapEvents,
                    "changelayer": this.handleMapEvents,
                    scope: this
                });
                activated = true;
            }
            return activated;
        }
    });
