fitbounds

问题 I cannot figure out how to call fitBounds() on the Leaflet map. If I was just using vanilla leaflet, this solution would work perfectly: Zoom to fit all markers in Mapbox or Leaflet Unfortunately, I am using react-leaflet. Here is the solution if I was just using leaflet by itself. var leafletMap = new L.featureGroup([marker1, marker2, marker3]); map.fitBounds(leafletMap.getBounds()); I think this code (my code) this.mapRef.current.leafletElement is equivalent to var leafletMap = new L

问题 My Google maps API map zooms put to show all the markers added after a google places search. On a mobile map this can take a bit to load and as this app for cyclists I prefer to only show the results within the viewport. Most research I read indicates it is not possible to only return results within the view port. Is it possible for me to just keep the map bounds from changing after the markers are added? It would be great if it would just show me the markers added to the current bounds

问题 I've just begun using the Google Maps API (v3.0) and have had a good deal of success so far. I am loading a set of objects with Latitude & Longitude values from a database, passing them into my script, and looping over them in the script in order to add them to the map. I am using the " bounds.extend() / map.fitBounds() " method of setting the map's zoom & bounds (see code below), which works as expected the first time around; however, if I clear out the existing markers, fetch another set of

问题 I have a map which contains multiple markers with infowindows. The infowindows need to be open on page load. The map is being centered using setbounds to incorporate all of the markers, which works, but it also needs to include the infowindows within the bounds. Currently the infowindows are cropped in places. JS: function initialize() { var map = new google.maps.Map(document.getElementById('map-canvas')); var bounds = new google.maps.LatLngBounds(); var myLatlng1 = new google.maps.LatLng(51

问题 I am trying to render directions for 48 waypoints, but google only allows 8 waypoints to be rendered per request. so I do multiple requests (in my case 6). However, the API somehow doed fitBounds() for the last request. How can I show all the 48 waypoints in one map using fitBounds() and/or setZoom() My code is as below: - function DisplayDirection(directionList){ var interval = 8; // upper bound for usage limits in google directions API is 8 var startIndex =0; var maxmimumIndex =

问题 I'm working with this example from Geocodezip The markers on the map change depending on which category is selected. I would like them to automatically center on the category of markers but I'm having difficulty getting it to work. The issue I'm having with all the fitbounds examples I've found on here and elsewhere is that they require the markers to be defined in the Javascript whereas mine are being imported from an XML file. I'm not sure what to try next. The script: <script type="text

问题 I want to fitbound pushpins to visible all around user's location pushpin. i wrote the following code it center the user location but few pushpin goes out of map ?? FYI: userPinLoc is pushpin object which is already populated function setInitialZoom() { mapZoom = googleMap.getZoom(); var bounds = new google.maps.LatLngBounds(); bounds.extend(userPinLoc); for (i in nearestEntitiesToZoom) { entity = nearestEntitiesToZoom[i]; var googleLatLng = new google.maps.LatLng(entity.latitude,entity

问题 I have a problem with googlemaps fitBounds functions. for (var i = 0; i < countries.length; i++) { var country = countries[i]; var latlng = new google.maps.LatLng(parseFloat(country.lat), parseFloat(country.lng)); mapBounds.extend(latlng); } map.fitBounds(mapBounds); Some icons will be displayed outside the viewport / Visible area. And idea? Thanks in advance. 回答1: Consider the following example, which will generate 10 random points on the North East USA, and applies the fitBounds() method. <

问题 In the app I'm creating, I dynamically add groups of points to a featureGroup that is referenced in a nested map click event. So the gist is that I have a map of a country with different regions displayed. Clicking a region fits the map bounds to that polygon and reveals points associated with that polygon, let's say cities. Clicking on a single point/city bores down further and reveals another group of points associated with the first clicked point, such as all libraries within the selected

问题 I'm calling getBounds() directly after a call to fitBounds(), and I thought I'd get a valid bound back as the map recenters and zooms to fit the bounds. Unfortunately, getBounds() is returning nil.
