javascript - 如何在 map 循环 Leaflet JS 上复制标记位置

Question

我正在使用 Leaflet JS 构建自定义 map (带有自定义图 block )，它从东到西循环。我添加了几层标记和多边形(以指示 map 中的路线)并且每个标记中都有弹出日期。我想在原始图层左右两侧的克隆 map 循环中看似相同的位置复制标记/多边形图层。

  var mapMinZoom = 2;
  var mapMaxZoom = 6;

  var tiles = L.tileLayer('../bigger_map/{z}/{x}/{y}.png', {
    unloadInvisibleTiles : false,
    reuseTiles : true,
    updateWhenIdle : false,
    continousWorld : true,
    noWrap: false          
  });

  var marker = L.marker([-110.25, 120.6875]).bindPopup("<iframe src='http://player.vimeo.com/video/114950712'>Vimeo</iframe>"),
      markerSecond = L.marker([ -85.71875, 111.8125]).bindPopup("<a href='#vid' class='fancybox-media'>  click me </a>"),
      markerThird = L.marker([ -71, 100]).bindPopup("<a href='#vid' class='fancybox-media'>  click me </a>"),
      markerFourth = L.marker([ -62.75, 82.75]).bindPopup("<iframe src='http://player.vimeo.com/video/114950712'>Vimeo</iframe>"),
      markerFifth = L.marker([ -52.5, 48]).bindPopup("<a href='#vid' class='fancybox-media'>  click me </a>"),
      markerSixth = L.marker([ -75.75, 57]).bindPopup("<a href='#vid' class='fancybox-media'>  click me </a>");

  var polygon = L.polygon([ [-110.25, 120.6875], [ -85.71875, 111.8125] ]),
      polygonSecond = L.polyline([ [-85.71875, 111.8125], [ -71, 100] ]), 
      polygonThird = L.polyline([[ -71, 100], [ -62.75, 82.75] ]),
      polygonFourth = L.polyline([[ -62.75, 82.75], [ -52.5, 48] ]),
      polygonFifth = L.polyline([ [ -52.5, 48],  [-75.75, 57] ]);   

  var americaTour = L.layerGroup([marker, markerSecond, markerThird, markerFourth, markerFifth, markerSixth]); 
  var americaPolys = L.layerGroup([ polygon, polygonSecond, polygonThird, polygonThird, polygonFourth, polygonFifth]);   

  var map = L.map('map', {
    maxZoom: mapMaxZoom,
    minZoom: mapMinZoom,
    layers: [tiles, americaTour, americaPolys],
    //inertia options
    //where the map builds momentum while dragging and continues moving in the same direction for some time.
    inertiaDecelartion : 3000,
    inertiaMaxSpeed    : 1500,
    inertiaThershold   : 32,
    crs: L.CRS.Simple
  });

  var mapBounds = new L.LatLngBounds(
      map.unproject([0, 14295], mapMaxZoom),
      map.unproject([15816, 0], mapMaxZoom));

  map.fitBounds(mapBounds);

 map.panTo(new L.LatLng(-110.25, 120.6875));
}

如有任何帮助，我们将不胜感激。已尝试以各种方式搜索此内容，但 Leaflet 示例中没有一个实际上具有此功能。

在您的 map 选项中使用 'worldCopyJump': true。

With this option enabled, the map tracks when you pan to another "copy" of the world and seamlessly jumps to the original one so that all overlays like markers and vector layers are still visible.
