title: Leaflet Uncaught Error: Invalid LatLng object: (NaN, NaN)
body: <p>I am trying to load map markers dynamically with leaflet and am getting this error:</p>
  
  <blockquote>
    <p>Uncaught Error: Invalid LatLng object: (NaN, NaN)</p>
  </blockquote>
  
  <p>I am using this javascript to load my markers:</p>
  
  <pre><code>            var lat;
              var lng;
  
  
              for (i = 0; i &lt; data.length; i++) {
                  lat = parseFloat(data[i].lat);
                  lng = parseFloat(data[i].lng);
  
                  L.marker([lat, lng]).addTo(map);
              }
  </code></pre>
