gpx verilerini Google haritalarında gösterme API

Question

Büyük bir sorunum var.

InvalidValueError: in property path: at index 0: not a LatLng or LatLngLiteral: in property lat: not a number

google.load('visualization', '1', {packages: ['columnchart']}); 

$.ajax({ 
url: "cartes/map.gpx", 
type: "GET", 
datatype: "xml", 
success:function(xml){ 

    var lat = new Array(); 
    var lng = new Array(); 
    var coordonneesMap = new Array(); 
    var samples = 256; 
    var i = 0; 

    $(xml).find("trkpt").each(function(){ 
     lat[i] = $(this).attr("lat"); 
     lng[i] = $(this).attr("lon"); 

     i++; 
    }); 

    var maxPath = Math.round(lat.length/samples); 
    console.log(maxPath); 
    var path = []; 

    if (maxPath > 1) 
    { 
     for(var i in lat) 
     { 
      if((i %maxPath) == 0) path.push({'lat':lat[i],'lng':lng[i]}); 
     } 
    } 

    console.log(path) 

    var elevator = new google.maps.ElevationService; 

    elevator.getElevationAlongPath({ 
     'path': path, 
     'samples': samples 
    }, plotElevation); 


} 
}); 

function plotElevation(elevations, status) { 
    var chartDiv = document.getElementById('elevation_chart'); 
    if (status !== google.maps.ElevationStatus.OK) { 
    // Show the error code inside the chartDiv. 
    chartDiv.innerHTML = 'Cannot show elevation: request failed because ' + 
     status; 
    return; 
    } 
    // Create a new chart in the elevation_chart DIV. 
    var chart = new google.visualization.ColumnChart(chartDiv); 

    // Extract the data from which to populate the chart. 
    // Because the samples are equidistant, the 'Sample' 
    // column here does double duty as distance along the 
    // X axis. 
    var data = new google.visualization.DataTable(); 
    data.addColumn('string', 'Sample'); 
    data.addColumn('number', 'Elevation'); 
    for (var i = 0; i < elevations.length; i++) { 
    data.addRow(['', elevations[i].elevation]); 
    } 

    // Draw the chart using the data within its DIV. 
    chart.draw(data, { 
    height: 150, 
    legend: 'none', 
    titleY: 'Elevation (m)' 
    }); 
}

sizin lat/lng değerleri numaralarını olun:

Chrome'un konsol söylüyorlar ... Web sitemde benim gpx veri telafi etmek istiyorum ama sorunun nerede olduğunu bilmiyorum:

$(xml).find("trkpt").each(function(){ 
    lat[i] = parseFloat($(this).attr("lat")); 
    lng[i] = parseFloat($(this).attr("lon")); 
    i++; 
}); 

Veya:

if((i %maxPath) == 0) path.push({'lat':parseFloat(lat[i]),'lng':parseFloat(lng[i])});
