Push Lat Lng from another function into Street View Image API

Question

I'm using the Google Maps JavaScript API and this solution for getting closest points on the map and displaying them.

"pt" value example:

38.5803844,-121.50024189999999

Here is the code:

function findClosestN(pt,numberOfResults) {

    var closest = [];

    for (var i=0; i<gmarkers.length;i++) {
         gmarkers[i].distance = google.maps.geometry.spherical.computeDistanceBetween(pt,gmarkers[i].getPosition());
         gmarkers[i].setMap(null);
         closest.push(gmarkers[i]);
       }
       closest.sort(sortByDist);
       return closest;
    }

    function sortByDist(a,b) {
       return (a.distance- b.distance)
    }

    function calculateDistances(pt,closest,numberOfResults) {
      var service = new google.maps.DistanceMatrixService();
      var request =    {
          origins: [pt],
          destinations: [],
          travelMode: google.maps.TravelMode.DRIVING,
          unitSystem: google.maps.UnitSystem.IMPERIAL,
          avoidHighways: false,
          avoidTolls: false
        };
      for (var i=0; i<closest.length; i++) request.destinations.push(closest[i].getPosition());
      service.getDistanceMatrix(request, function (response, status) {
        if (status != google.maps.DistanceMatrixStatus.OK) {
          alert('Error was: ' + status);
        } else { 

          var origins = response.originAddresses;
          var destinations = response.destinationAddresses;
          var outputDiv = document.getElementById('search_results');
          outputDiv.innerHTML = '';

          var splitLoc = pt;
          splitLoc.split(",");
          alert(splitLoc[1]);

          photo_lat = splitLoc[0]; // lat
          photo_lng = splitLoc[1]; // lng

          profile_photo = "https://maps.googleapis.com/maps/api/streetview?size=600x300&location=" + photo_lat + "," + photo_lng + "&heading=151.78&pitch=-0.76";

          var results = response.rows[0].elements;
          for (var i = 0; i < numberOfResults; i++) {
            closest[i].setMap(map);
            outputDiv.innerHTML += "<div class='location_list' style='background:url(" + profile_photo + ");'>" + "<div class='inner'>" + "<a href='javascript:google.maps.event.trigger(closest["+i+"],\"click\");'>"+closest[i].title + '</a><br>' + closest[i].address+"<br>"
                + results[i].distance.text + ' appoximately '
                + results[i].duration.text
                + "</div></div>";
          }
        }
      });

}

In the last function, calculateDistances, I am trying to split the coordinates from the "pt" variable and then pass the lat and lng into the street view image api to output a static image of each location.

I get the error:

Uncaught TypeError: splitLoc.split is not a function

when trying to split pt. My guess is that pt is not in the right format to be split but I can't figure it out. When I alert pt by itself it displays the lat and lng together correct, but the error is occurring on the split.

How can I split pt into separate lat lng and then pass it in?

Answer 1

pt is not a string, but an object with properties lat and lng. But if you call alert(pt) it will cast the object as string.

for example

pt.toString() "(37.4418834, -122.14301949999998)"

To get lat/lng just use pt.lat() or pt.lng()
