Markerclusterer-基于连续标记数组中的特定ID触发特定标记的点击事件

Question

Before implementing MarkerClusterer, I've been able to trigger the click event of specific markers (which then brings up a panel specific to that marker) by first loading up the marker array like this:

markers[marker.id] = marker;

(Where marker.id is a property set when drawing the marker from the JSON, that corresponds to a user record in my database)

Then calling:

google.maps.event.trigger(markers[id], 'click');

(Where 'id' is the user's id I want to click the marker for)

Now that I want to use MarkerClusterer however, it won't cluster using the array loading method I use above, I assume because there are then 'gaps' in my marker array as I don't draw markers for all users.

...MarkerClusterer works when I load my marker array like this:

markers.push(marker);

I assume this gives a continuous array without gaps that MarkerClusterer can read... but now I can't trigger the correct marker's click by it's index in the array.

So it seems I need a way of finding the .indexOf a marker in the continuous marker array based on marker.id...

Any help would be much appreciated.

You have at least 2 options:

1. iterate through the "continuous" array of markers looking for the one that has the correct id (inefficient, requires additional processing with large numbers of markers), then trigger the click event on that.
2. create your associative array also, use it for triggering the click event (inefficient, requires memory for an additional array)
