我的事件监听器有问题。我在“地图”中创建了“点击”事件侦听器，每次用户点击地图时都会创建一个新标记。每个标记都有自己的信息框，其中包含删除标记的链接。

问题是当我单击信息框中的删除链接时，总是会触发地图的单击事件。标记已成功删除，但它会创建一个新标记。我怎样才能解决这个问题？我只想删除标记。

这是代码：

<style type="text/css">
  html { height: 100% }
  body { height: 100%; margin: 0; padding: 0 }
  #map_canvas { height: 100% }

将点击事件作为参数传递给 removeMarker()

    marker = new google.maps.Marker({
        map:map,
        draggable:true,
        animation: google.maps.Animation.DROP,
        position: location,
        html: '<a href="#" onclick="removeMarker('+ (markers.length) +',event)">\
                delete marker</a> <br/> '+ location
     });

然后您将能够停止事件的传播：

function removeMarker(index,event)
{   
    try{event.cancelBubble=true;}//IE
    catch(e){event.stopPropagation();}//others

    markers[index].setMap(null);
    infowindow.close(map, markers[index]);
    return false;
}

谢谢回复。我已经解决了这个问题。我通过删除“onclick”并将javascript放置到href来修复它 <a href='javascript: removeMarker(index)'> remove </a>
