如何在 IE 和 Firefox 中使用 Google 地图 v3 将点击事件绑定到自定义叠加层
我已经在google文档的指导下对我的overlay对象进行了子类化，我的onAdd()函数如下所示：
MyOverlay.onAdd() {
var div_parent = document.createElement("DIV");
var div_child = document.createElement("DIV");
div_child.innerHTML = "Click Me";
div_parent.appendChild( div_child );
this.getPanes().overlayLayer.appendChild(div_parent);
var this = that;
google.maps.event.addDomListener( div_parent, 'click', function(){
google.maps.event.trigger(that, 'click'); // from [http://stackoverflow.com/questions/3361823/make-custom-overlay-clickable-google-maps-api-v3]
alert("Clicked");
} );
}
我的代码只能在IE中运行良好，但在Firefox和Chrome中，点击事件将不再被触发。
那么如何解决问题呢？
I've already subclass my overlay object under the instruction of google document, and my onAdd() function is listed below:
MyOverlay.onAdd() {
var div_parent = document.createElement("DIV");
var div_child = document.createElement("DIV");
div_child.innerHTML = "Click Me";
div_parent.appendChild( div_child );
this.getPanes().overlayLayer.appendChild(div_parent);
var this = that;
google.maps.event.addDomListener( div_parent, 'click', function(){
google.maps.event.trigger(that, 'click'); // from [http://stackoverflow.com/questions/3361823/make-custom-overlay-clickable-google-maps-api-v3]
alert("Clicked");
} );
}
My code can work well ONLY in IE, but in Firefox and Chrome, the click event will not be triggered anymore.
So how to solve the problem?

您应该使用overlayMouseTarget，而不是使用overlayLayer mapPanes。
参考：http://code.google.com/apis/maps/documentation/javascript/ overlays.html#CustomOverlays
Instead of using overlayLayer mapPanes, you should use overlayMouseTarget.

我知道这是一篇旧文章，但如果您想知道，这里是解决方案：
在上面的代码中，您需要将覆盖函数更改为：
到：
I know this is an old post, but if you were wondering, here is the solution:
In your code above, you need to change the overlay function from:
to:
另请注意，尽管即使您使用覆盖窗格，您的单击事件也会在桌面上捕获，但要使触摸事件起作用，鼠标目标窗格是必要的。
Also note although your click events will be captured on desktop even if you use overlay pane, for touch events to work, mouse target pane is necessary.
