I want to display properties as popup but I don't know why it is empty. The line where you create and bind your popup should have been included in the onEachFeature option of your L.

Having this line outside the factory makes it access your outer scope layer variable, which is actually the GeoJSON Layer Group that holds all the features from your GeoJSON data, therefore it tries to bind a popup on each of these features in your case, there is only 1 marker, but it could be more.

I have two polygons on a map that are a default blue. I want to style the polygons based on whether a value 'Ethnic1' is higher than a number like so:. Note: For brevity, this is just for "Ethnic Group 1". In my real world map, I have over 13 ethnic groups I am modeling. Ethnic1 property, also adjusting the appearance a bit and adding a nice touch with dashed stroke.

Then, since we will have more than one ethnic group to style, I will use a switch statement to style it:. As said in the question comments, unfortunately you cannot use feature. You have to provide before hand a way for the user to indicate which "ethnic" to use, so that you can apply the corresponding styling function.

Then use a default styling function for the initial display here I use Ethnic1and attach listeners on your radio inputs to change that styling function when the user clicks on the radios:.

Ask Question. Asked 4 years, 1 month ago. Active 4 years, 1 month ago. Viewed 12k times. I want to style the polygons based on whether a value 'Ethnic1' is higher than a number like so: Note: For brevity, this is just for "Ethnic Group 1". Ethnic1weight: 2, opacity: 1, color: 'white', dashArray: '3', fillOpacity: 0. What am I doing wrong? Styling the features based only on the value of Ethnic1 should be easy enough, but for multiple ethnic groups, it's a little unclear what your expected output would look like.

Each of your features has properties for multiple ethnic groups, Ethnic1 through Ethnic6. Are you intending to only display one ethnic group at a time? And if so, do you want to use a different color scale depending on which ethnic group is chosen, or do you want to use the same scale for all i. It will never match any string of type 'Ethnic1' in your switch statement.

I want to also use a radio button to toggle not checkmarks so people can't toggle on more than one group at a time.

The styling attributes in the spec are also properties, so should always work wherever geoJSON is expected. This styling is also used by Github's geojson rendering which is built on leaflet : help.

Tries to locate the user using the Geolocation API, firing a locationfound event with location data on success or a locationerror event on failure, and optionally sets the map view to the user's location with respect to detection accuracy or to the world view if geolocation failed.

Creates a new map pane with the given name if it doesn't exist already, then returns it. The pane is created as a child of containeror as a child of the main map pane if not set. Returns a plain object containing the names of all panes as keys and the panes as values. Runs the given function fn when the map gets initialized with a view center and zoom and at least one layer, or immediately if it's already initialized, optionally passing a function context.

Returns the minimum zoom level of the map if set in the minZoom option of the map or of any layersor 0 by default. Returns the maximum zoom level of the map if set in the maxZoom option of the map or of any layers. Returns the maximum zoom level on which the given bounds fit to the map view in its entirety. If inside optional is set to truethe method instead returns the minimum zoom level on which the map view fits into the given bounds in its entirety.

Did you try what I suggested? For paths lines, polygons, etc. For markers, no, because you will have to change the icon, which is a png, not an svg path. Unless there is a more "MapBox" way of doing this? Not sure.

My primary goal is to call fitBounds whenever a FeatureGroup is rendered in react-leaflet on initial load. However, because it is using a function instead of React component, I don't have access to using React hooks. The alternative that I tried does not work, even though it is the same code wrapped in a React component.

I am a bit stumped, since this is the same code. The getLayers function returns a ReactNode in both cases. However, when moving to a standalone ControlledGroup component, it throws an error on render. I tried creating a custom class component for react-leaflet, but the difficulty that I ran into there is that createLeafletElement returns a Leaflet. Elementwhereas I am simply looking to return a ReactNode. That is, all of these are valid react-leaflet components already. My questions - why does one work and the other does not?
