javascript - 尝试在标记单击时从 JSON 检索值

Question

当我单击特定的 map 标记 (leaflet.js) 时，如何从 geoJSON 中检索 value 属性？我尝试过以下类似的代码，但似乎无法让它工作。

示例 geoJSON

var geojsonFeature = {
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "marker-color": "#f85047",
                "marker-size": "medium",
                "value": 130
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    146.3622826337814,
                    -41.187067757423826
                ]
            }
        },
    ]
};

JS

marker.on('click', function(e){
    alert(this.geojsonFeature.features.properties.value);
});

这是JSFiddle
