Google Maps API v3:点击firefox中未触发的自定义标记事件

创建了一张地图,我试图让其功能类似于“我的地图”。我在右侧有两个下拉列表,根据这些ddl中的选择,您可以添加自定义标记/图标。选择标记类型,然后单击地图右上角的“+”按钮,然后单击要添加标记的位置。我的问题是,这在IE,Safari和Chrome中运行良好,但在Firefox中不行。点击事件似乎没有触发。

在右上角添加标记的按钮有一个指向我的'placeMarker()'函数的onclick事件。这是placeMarker(),createMarker()...

的代码
function placeMarker() {

    select("placeMarker");

    var infowindow = new google.maps.InfoWindow({}); 
    var catID = document.getElementById('category');
    var typeID = document.getElementById('ddlType');
    var category = catID.options[catID.selectedIndex].value;
    var markerType = typeID.options[typeID.selectedIndex].value;

    if (!markerType) {
        alert("You must select an icon type.");
    } 
    else {
        var moveListener = google.maps.event.addListener(customMap, 'mousemove', function(event) {
            if (mapMarker) {
                mapMarker.setPosition(event.latLng);
            } else {
                mapMarker = createMarker(event.latLng, "test", markerType, "test");
            }
        });

        var clickListener = google.maps.event.addListener(customMap, 'click', function(event) {
            if (mapMarker) {
                select("hand_b");
                google.maps.event.clearListeners(customMap, 'mousemove');
                google.maps.event.removeListener(listener);
                mapMarker = createMarker(event.latLng, "test2", markerType, "test");

                var htmlInfo = "" +
                    "Category:" + category + "" +
                    "Item:" + markerType + "" +
                    "Notes:" +
                    "Location:" + mapMarker.getPosition().toString() + "" +
                    "" +
                    "";

                //infowindow.setContent(htmlInfo);
                //infowindow.open(customMap, mapMarker);
            }
        });
    }
}

function createMarker(latlng, title, icon, html) {
    var mapMarker = new google.maps.Marker({
        position: latlng,
        map: customMap,
        title: title,
        icon: 'Images/' + icon + '.png'
    });
    return mapMarker;
}

function select(buttonId) {
    document.getElementById("hand_b").className = "unselected";
    document.getElementById("placeMarker").className = "unselected";
    document.getElementById(buttonId).className = "selected";
}

任何帮助或建议都会很棒。这可能是ff中的一个错误吗?

我为开源灾难软件包做了类似的事情。在这种情况下,我们假设我在下拉菜单中选择了“Fire”,这会触发addFire()。标记上的侦听器将删除单击上的点或允许您拖动它。地图一次只能有一个侦听器,但每个标记仍然可以同时拥有自己的侦听器。

以下是适用于Chrome,Firefox和IE8的代码:

//This function sets up the map for adding a fire icon
function addFire() {
 //Kill old listener
 if(listening)
  google.maps.event.removeListener(listenerhandle);

 //Start new listener
 listenerhandle = google.maps.event.addListener(disasterMap, 'click', addFirePoint);
 listening = true;
}//end addFire

//This function adds new fire points to the map and controls dragging and clicking
function addFirePoint(event) {
 //Create the marker
 var fireMarker = new google.maps.Marker({
  icon: "./mapimgs/fire.png", position: event.latLng, map: disasterMap, draggable: true });

 newFireMarkers.push(fireMarker);
 fireMarker.setTitle("Fire");

 //Listen for clicks on the new marker
 google.maps.event.addListener(fireMarker, 'click', function() {
      fireMarker.setMap(null);
   //remove the marker from the array
   for(i=0;i
