有没有办法用poplet绑定弹出窗口中的多个属性？

我正在加载一个如下所示的JSON文件：

              ]
            ]
        }
    }
    ]
}

如您所见，有几个属性。我目前正在使用此代码

    L.geoJson(jsonObject, {
    onEachFeature: function (feature, layer) {
        layer.bindPopup(feature.properties.name);
    }
}).addTo(map);

有没有办法将＆gt; 1属性绑定到弹出窗口？

Answer 1

在JavaScript中使用+到concatenate字符串。

E.g。 feature.properties.name + " " + feature.properties.venue_type + ...

如何使用传单bindPopup多个功能属性？
