Accessing current latitude and longitude? about google-map

[bestguy]

Note I do not want a marker - I want the current map center

[robdodson]

Can you grab them from the map?

document.querySelector('google-map').map.getCenter()

[bestguy]

Thanks, partly, though how do I know when they have changed?

You should be able to access map.latitude and map.longitude to get the current points. Likewise for zoom.

var mapEl =  document.querySelector('google-map');
console.log(mapEl.latitude, mapEl.longitude);

We haven't exposed an event for when the center changes, but you can get at it two ways:

1. data binding to the latitude/longitude attribute of the map element.

2. add a listerner directly on the maps api object:

   google.maps.event.addListener(mapEl.map, 'center_changed', function() {...});

Thanks, is this by design, or would you be open to a pull request to add this?

It's one of those things that's fairly easily to setup without the element adding additional features. This is one reason we expose the maps api object on the element. People can do whatever they want with it and we don't need to cover 100% of the API feature set. That said, and updated center is fairly common and a 1 line addition. PR welcome :)

Thanks, will do
