打字稿/谷歌地图：如何确定点击了哪个标记

Question

我有一组标记对象markers。然后我使用for循环向它们添加事件侦听器。但是，我似乎无法弄清楚如何确定点击标记的WHICH。

以下是我现在的代码：

for(var i = 0; i < this.markers.length; i++) //adds listener to all markers
{
  google.maps.event.addListener(this.markers[i], "click", () =>
  {
    //need to get access to which marker was clicked
    //need to use arrow function to retain proper reference to "this"
  }); 
}

我已尝试将参数传递给箭头函数，但似乎没有任何效果。有什么想法吗？

Answer 1

for each ( var marker in this.markers ) {
    with( { mark: marker } ) { // <- mark will contain the marker, and keep it all the way
        google.maps.event.addListener( mark, 'click', function() {  
            return mark; // <- this will return the actual marker
        } );
    }
}
