Google Maps API v3 - 为什么没有上下文与事件？ [英] Google Maps API v3 - why no context with events?

问题描述

第一次使用Google Maps API v3，并且我有一堆标记的地图。我想要这样做，当你点击一个，一个特定的InfoWindow将显示（特定于您点击的标记）。我真的很惊讶，点击事件并没有告诉你点击的实际标记！

Using Google Maps API v3 for the first time and I've got a map with a bunch of markers. I wanted to make it so when you click one, a specific InfoWindow will display (specific to the marker you clicked). I was really surprised that the click event doesn't tell you the actual marker that was clicked!

我知道有一个解决方案使用单独的方法来创建一个关闭，但是这似乎是对我的一个黑客。有更好的方法吗？或者，有没有办法问地图什么标记存在于这个位置，并从事件参数中传递位置？

I know there is a solution using a separate method to create a closure but that seems like a hack to me. Is there a better way to do it? Or, is there a way to ask the map "what markers exist at this position" and pass in the position from the event argument?

我预计事件将像这样工作：

I expected events to work like this:

google.maps.event.addListener(marker, 'click', function(event, obj)
{
    //Now I can work with "obj" - the thing that was clicked.
});

推荐答案

您应该在事件中引用this监听器。

You should just refer to 'this' in the event listener.

google.maps.event.addListener(marker, 'click', function(e) {
  // this == marker;
  // e == MouseEvent
});
