如何使用傳單綁定多個功能屬性？

Question

有沒有辦法在彈出窗口中綁定多個屬性？

我加載一個JSON文件看起來像這樣：

{ 
    "type": "FeatureCollection", 
    "features": 
    [ 
     { 
     "type": "Feature",

正如你所看到的，有幾個屬性。 我目前使用此代碼

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

是否有> 1個propertie結合彈出的方法嗎？

Answer 1

使用+至concatenate JavaScript中的字符串。

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