使用mapbox基于geojson定义多边形填充颜色

我使用mapbox示例在地图上创建多个多边形,每个多边形都有弹出事件。我的问题是,我需要根据每个多边形的geojson属性设置不同的填充颜色。

This 这是我的例子。

mapboxgl.accessToken = 'pk.eyJ1IjoibWFoYW5tZWhydmFyeiIsImEiOiJ6SDdSWldRIn0.8zUNm01094D1aoSeHpWYqA';
var map = new mapboxgl.Map({
    container: 'map',
    style: 'mapbox://styles/mapbox/streets-v9',
    center: [51.40545845031738,
    35.75069181054449],
    zoom: 10

});

map.on('load', function (e) {
    // Add a layer showing the state polygons.
    map.addLayer({
        'id': 'states-layer',
        'type': 'fill',
        'source': {
            'type': 'geojson',
            'data': 'geojson.js'
        },
        'paint': {
            'fill-color': 'rgba(200, 100, 240, 0.4)',
            'fill-outline-color': 'rgba(200, 100, 240, 1)'
        }
    });

    // When a click event occurs on a feature in the states layer, open a popup at the
    // location of the click, with description HTML from its properties.
    map.on('click', 'states-layer', function (e) {
        new mapboxgl.Popup()
            .setLngLat(e.lngLat)
            //.setHTML(e.features[0].properties.name)
            .setHTML("<h1>"+e.features[0].properties.userone+"</h1>"+e.features[0].properties.name)

            .addTo(map);
    });

    // Change the cursor to a pointer when the mouse is over the states layer.
    map.on('mouseenter', 'states-layer', function () {
        map.getCanvas().style.cursor = 'pointer';
    });

    // Change it back to a pointer when it leaves.
    map.on('mouseleave', 'states-layer', function () {
        map.getCanvas().style.cursor = '';
    });
});

'paint': {
    'fill-color': 'rgba(200, 100, 240, 0.4)',
    'fill-outline-color': 'rgba(200, 100, 240, 1)'
}

在我的geojson文件中,我有一个颜色键:

"type": "Feature",
"properties": {
    "userone":"پیروزی",
    "name":"North Dafkota",
    "featureclass":"Admin-1 scale rank",
    "color":"red"
}
