Question

我是用超文本制作地图的新鲜事,我一直试图在基图(道路)上增加两层病媒(地点、点),但我看不到地图上的病媒层。层层应当成为基图的传导器。各个层次的分布在层交换器上,但并未在屏幕上展示。我认为,问题在于如何呼吁病媒层。如何展示病媒层。成就

var map = new OpenLayers.Map("map-id");

    var roads= new OpenLayers.Layer.WMS(
    "roads",
    "http://localhost:8080/geoserver/wms",
    {layers: "roads"});

var points= new OpenLayers.Layer.Vector(
    "points",
    "http://localhost:8080/geoserver/wms",
    {layers: "points"});

var places= new OpenLayers.Layer.Vector(
    "places",
    "http://localhost:8080/geoserver/wms",
    {layers: "places"});

map.addLayer(roads);
map.addLayer(points);
map.addLayer(places);
map.addControl(new OpenLayers.Control.LayerSwitcher());

你正试图通过MS协议展示你的病媒数据。为此,你应使用开放式电车,而是使用开放式电车。 OpenLayers. Layer.Vector. 在超时使用时显示WMS层是Base Layer的选择:

map = new OpenLayers.Map( map ); 
var places = new OpenLayers.Layer.WMS( places ,
  "http://localhost:8080/geoserver/wms",
  {layers: "places", transparent: true},
  {isBaseLayer: false, opacity: 1, singleTile: true, visibility: true}
);
map.addLayers([places]);
