Leaflet 如何在传单多边形上触发本机弹出窗口

如何手动触发传单多边形上的本机弹出窗口？

我可以将本机弹出窗口绑定到每个层，如下所示：

geojsonLayer.on("featureparse", function (e){
    // bind the native popup
    var popupContent = "popup content goes here";
    e.layer.bindPopup(popupContent);
});

map._layers['poly0']

map._layers['poly0'].openPopup();

map._layers['poly0'].openPopup is not a function

我已经手动为每个多边形指定了一个ID，以便以后可以像这样引用它们：

geojsonLayer.on("featureparse", function (e){
    // bind the native popup
    var popupContent = "popup content goes here";
    e.layer.bindPopup(popupContent);
});

map._layers['poly0']

map._layers['poly0'].openPopup();

map._layers['poly0'].openPopup is not a function

我尝试过像这样触发弹出窗口：

geojsonLayer.on("featureparse", function (e){
    // bind the native popup
    var popupContent = "popup content goes here";
    e.layer.bindPopup(popupContent);
});

map._layers['poly0']

map._layers['poly0'].openPopup();

map._layers['poly0'].openPopup is not a function

但这给了我这样一个错误：

geojsonLayer.on("featureparse", function (e){
    // bind the native popup
    var popupContent = "popup content goes here";
    e.layer.bindPopup(popupContent);
});

map._layers['poly0']

map._layers['poly0'].openPopup();

map._layers['poly0'].openPopup is not a function

知道我哪里出了问题吗？

矢量层openPopup最近才出现在最新版本中，以前没有

另外，请查看传单0.4发布公告：（注意GeoJSON API已更改，并且它不向后兼容，因此您还必须更新代码）
