Question

我想使用leaflet.js突出显示地图上的特定街道，我目前正在使用带有数组数据的折线。

        var grayscale   = L.tileLayer(mbUrl, {id: 'mapbox.light', attribution: mbAttr}),
            streets  = L.tileLayer(mbUrl, {id: 'mapbox.streets',   attribution: mbAttr});

    var baseMaps = {
    "Grayscale": grayscale,
    "Streets": streets
};

function initmap () {
var map = L.map('map', {
    center: [-1.2833, 36.8167],
    zoom: 12,
    layers: [grayscale]
});
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
L.control.layers(baseMaps).addTo(map);
var polyline = L.polyline([
    [-1.26135173, 36.84151411],
    [-1.25879889, 36.84619188],
    [-1.25824112, 36.84779048],
    [-1.25815531, 36.8516314],
    [-1.25781207, 36.85304761],
    [-1.25714704, 36.85439944],
    [-1.25410078, 36.85798287]
    ]
            ).addTo(map);
}

</script>
</body>

从上面的例子可以看出，我已经能够选择Thika路的一部分，但由于我一点一点地定义，我需要定义超过100条道路/街道，这将是乏味的。有走动吗？
