Question

我正在使用Mapbox加载地图，看来地图已放大到最大。我希望地图看起来更小。如何放大地图加载？

这是加载地图的代码。该代码加载了我的当前位置，看起来很大。我希望地图默认为放大，而不必单击+-来放大和缩小地图。谢谢。

list = [3, 3, 5, 2, 7, 2, 3, 0, 0, 0, 0, 4]
MaximumValue = 4
 Step 1: [3, 3, 5, 2, 7, 2, 3, 0, 0, 0, 0, 4]
         [3, 3, 5, 2, 7, 1, 4, 0, 0, 0, 0, 4]
         [3, 3, 5, 2, 4, 4, 4, 0, 0, 0, 0, 4]
         [3, 3, 3, 4, 4, 4, 4, 0, 0, 0, 0, 4]
         [3, 2, 4, 4, 4, 4, 4, 0, 0, 0, 0, 4]
 Finish: [1, 4, 4, 4, 4, 4, 4, 0, 0, 0, 0, 4] #reached lists[0] so stop program

您可以使用map.setView([latitude, longitude], zoom);：

L.mapbox.accessToken = 'pk.eyJ1IjoidGltbGlzdGVuIiwiYSI6ImNqaWs5eWltbTAybG8za21zNjVuZjg5MW4ifQ.xCKtim61H1YXAkU5KT9-FQ';
var map = L.mapbox.map('map', 'mapbox.streets');
map.setView([40.7290255, -74.0026558], 13);

var myLayer = L.mapbox.featureLayer().addTo(map);

// This uses the HTML5 geolocation API, which is available on
// most mobile browsers and modern browsers, but not in Internet Explorer
//
// See this chart of compatibility for details:
// http://caniuse.com/#feat=geolocation
if (!navigator.geolocation) {
    geolocate.innerHTML = 'Geolocation is not available';
} else {
      map.locate();
}

// Once we've got a position, zoom and center the map
// on it, and add a single marker.
map.on('locationfound', function(e) {
    map.fitBounds(e.bounds);

    myLayer.setGeoJSON({
        type: 'Feature',
        geometry: {
            type: 'Point',
            coordinates: [e.latlng.lng, e.latlng.lat]
        },
        properties: {
            'title': 'Here I am!',
            'marker-color': '#ff8888',
            'marker-symbol': 'star'
        }
    });

    // And hide the geolocation button
    geolocate.parentNode.removeChild(geolocate);
});

// If the user chooses not to allow their location
// to be shared, display an error message.
map.on('locationerror', function() {
    geolocate.innerHTML = 'Position could not be found';
});
