Generate random latitude and longitude with javascript after geolocation

问题

Is it possible with javascript to generate random latitude and longitude based on the user current position? I want to generate some random latitude and longitude positions after that the user is geolocated to place some markers on a leaflet map.

Yes you can, Code below:

var latBounds = [-122, -77];
  var lngBounds = [30, 50];
  
var features = [];

  for( var i=0; i<80000; i++ ){
    var lat = Math.random() * (latBounds[1]- latBounds[0] + 1) + latBounds[0];
    var lng = Math.random() * (lngBounds[1]- lngBounds[0] + 1) + lngBounds[0];
    features.push({
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [lat, lng]
      },
      "properties": {
        "title": "point_" +i,
        "marker-symbol": "harbor"
      }
    });
  }
  var geoJSON = {
    "type": "FeatureCollection",
    "features": features
  };
