leaflet open specific marker popup on button click

由 蹲街弑〆低调 提交于 2019-12-25 04:22:24
问题 I'm trying to open a specific marker's popup on some event(say, button click). In order to do so I add an id property to a marker and store all markers in an array.

问题 . . . because the tiles are absolutely positioned within parent containers whose heights are equal to zero. Here is the directive: https://github.com/tombatossals/angular-leaflet-directive I'm uncertain as to the appropriate channel by which to seek assistance since I'm dealing with a relatively small library.

Polygon layer has a white background which covers base maps

由 帅比萌擦擦* 提交于 2019-12-25 00:43:17
问题 I am currently creating a webmap with leaflet. I used leaflet.ajax to import polygons from a geojson. But the new polygon layer covers the basemap, resulting in the polygons on a white background. https://virgilxw.github.io/Singapore_Election_1955/ If you go the github page and navigate to the layer menu, you can find the polygon layer under "Data". I have tried re-ordering the layers, but moving the base map above the polygons just result in the polygons being covered. // Default base Map
