除了最后一件事外，我已经在这个谷歌地图 V3 上做了所有我想要的事情。现在，如果你加载地图，地图就可以搜索一个地方，然后将一个图标从地图外拖到谷歌地图中。但是，一旦图标在地图内，我就无法拖动它。我一直在无休止地搜索我的代码出错的地方。
以下是我阅读的许多示例：
Link1 , Link2 , Link3 , Link4（Link 4 是我需要的，但在进一步检查后无法连接代码）
我觉得我非常接近，但我相信我只是没有声明正确的变量或没有正确连接它们。下面是代码，这里是一个Fiddle，可以让您了解我的问题。（尝试拖动图标一次，然后在地图内再次拖动）

代码结束
如果你们能告诉我，那就太好了！另外，我注意到它marker被宣布了两次。这是问题之一吗？我尝试声明其他内容，但没有运气。我也遇到过这段代码，但不确定它在这种情况下是否有帮助
var overlay;
overlay = new google.maps.OverlayView();
overlay.draw = function() {};
overlay.setMap(map);
可能认为它与下面的这段代码有关？
function placeMarker(location, icon) {
var marker = new google.maps.Marker({
position: location,
map: map,
draggable:true,
icon: icon
});
}
但是话又说回来，不知道出了什么问题，我是否正确连接了变量？
非常感谢您的帮助，我非常接近完成我想要在这张地图上完成的任务
