问题 Salutations all and happy holidays. I Noticed an interesting behavioral quirk while trying to draw polygon layers with L.geoJson(). consider the following code: var polygonCoords = [ {"type": "Feature", "properties": {"group": "Violations"}, "geometry": { "type" : "Polygon", "coordinates": [[ [-107.69348, 43.22519], [-105.48523, 42.99259], [-107.7594, 42.26105] ]] } }]; and var polygons = L.polygon([ [43.22519, -107.69348], [42.99259, -105.48523], [42.26105, -107.7594] ]); Now, both work in

问题 I'd like to change the options text from edit control at Leaflet Draw. So instead of Save | Cancel | Clear All Display this text in another language. Same on the tooltips. Is it possible? 回答1: I solved in this way. L.drawLocal = { draw: { toolbar: { // #TODO: this should be reorganized where actions are nested in actions // ex: actions.undo or actions.cancel actions: { title: 'Cancel - your text-', text: '- your text-' }, finish: { title: '- your text-', text: '- your text-' }, undo: { title:

问题 What I want to do is pretty simple: I want my leaflet controls to be aligned side-by-side in rows rather than vertically as columns (as leaflet automatically does). Here is some short example code: library(shiny) library(leaflet) shinyApp( ui <- fluidPage( leafletOutput("map", width = "100%"), tags$head(tags$style(HTML(".leaflet-control-layers-overlays {width: 190px;}"))) ), server <- function(session, input, output){ output$map <- renderLeaflet({ leaflet() %>% addProviderTiles("Esri

问题 I have a leaflet map which uses a custom legend using HTML and added using the addControl function (following: Leaflet Legend for Custom Markers in R). However, I only want the legend to show when one group is shown, I have tried using the argument group = "group name" which doesn't work with the addControl function. I've also tried using layerId arguments but without success. Any ideas? Reproducible example: library(leaflet) # Sample Data data(quakes) quakes <- quakes[1:10,] # Choose Icon:

问题 I have a React-Leaflet map which I am rendering a div inside. For some reason, interacting with the contents of the div causes the map beneath to respond (eg: double-clicking will zoom the map, dragging will pan the map) - even when I'm calling e.stopPropagation() in handlers attached to the div. As I understand it, calling stopPropagation() should prevent the DOM events from ever reaching the map itself. Why does it appear that stopPropagation() is being ignored? How can I render a div
