Possible to iterate through markers after applying a query in a FusionTablesLayer?

Question

I currently have a filter working on a fusion table rendered as a Map Layer, and I want to zoom to best fit all of the data whenever the filter is changed.

The short answer is no. To me this is one of the shortcomings of dealing with Fusion Tables via the Maps API. E.g. wanting to display a count of the results of my most recent query. But there is a work-around through the "undocumented" JSONP API to Fusion Tables. I've had great success using it but I must credit Robin Kraft with informing me about this API. http://www.reddmetrics.com/2011/08/10/fusion-tables-javascript-query-maps.html.

Here's some code which allows you to re-execute your most recent query via an AJAX JSONP request and do what you want with the results, such as calculating the bounding-box. Note: this example uses Jquery for the AJAX JSONP calls. This example creates a

display but can be modified as needed.

 

// Example call
getFTData(tableid, 'latitude,longitude', example_dataHandler);

Since retrieving the count of recent Fusion Table rows returned is common, I'm adding a snippet of how to do that.
