我正在网站中创建OSM地图,并使用Openlayer添加一些标记。我的问题是,每次都会得到相同的标记图标。
<script type="text/javascript">
var map = new OpenLayers.Map("heatMap");
var mapnik = new OpenLayers.Layer.OSM();
map.addLayer(mapnik);
map.setCenter(new OpenLayers.LonLat(-4.0575942987957,54.390175926091) // Center of the map
.transform(
new OpenLayers.Projection("EPSG:4326"), // transform from WGS 1984
new OpenLayers.Projection("EPSG:900913") // to Spherical Mercator Projection
), 6 // Zoom level
);
var markers = new OpenLayers.Layer.Markers( "Markers" );
map.addLayer(markers);
var icon1 = new OpenLayers.Icon('http://www.openlayers.org/dev/img/marker.png', size, offset);
var icon2 = new OpenLayers.Icon('http://www.openlayers.org/dev/img/marker-gold.png', size, offset);
var icon3 = new OpenLayers.Icon('http://www.openlayers.org/dev/img/marker-green.png', size, offset);
var lonLat1 = new OpenLayers.LonLat(-4.0575942987957,54.390175926091).transform(
new OpenLayers.Projection("EPSG:4326"), // transform from WGS 1984
map.getProjectionObject() // to Spherical Mercator Projection
);
var lonLat2 = new OpenLayers.LonLat(-3.0575942987957,54.390175926091).transform(
new OpenLayers.Projection("EPSG:4326"), // transform from WGS 1984
map.getProjectionObject() // to Spherical Mercator Projection
);
var lonLat3 = new OpenLayers.LonLat(-5.0575942987957,54.390175926091).transform(
new OpenLayers.Projection("EPSG:4326"), // transform from WGS 1984
map.getProjectionObject() // to Spherical Mercator Projection
);
var marker1 = new OpenLayers.Marker(lonLat1);
var feature = new OpenLayers.Feature(markers, lonLat);
feature.closeBox = true;
feature.popupClass = OpenLayers.Class(OpenLayers.Popup.AnchoredBubble, { autoSize: true });
feature.data.popupContentHTML = '<p>Marker1<p>';
feature.data.overflow = "hidden";
marker1.feature = feature;
var markerClick = function (evt) {
if (this.popup == null) {
this.popup = this.createPopup(this.closeBox);
map.addPopup(this.popup);
this.popup.show();
} else {
this.popup.toggle();
}
OpenLayers.Event.stop(evt);
};
marker1.events.register("mousedown", feature, markerClick);
var marker2 = new OpenLayers.Marker(lonLat2);
var feature = new OpenLayers.Feature(markers, lonLat);
feature.closeBox = true;
feature.popupClass = OpenLayers.Class(OpenLayers.Popup.AnchoredBubble, { autoSize: true });
feature.data.popupContentHTML = '<p>Marker2<p>';
feature.data.overflow = "hidden";
marker2.feature = feature;
var markerClick = function (evt) {
if (this.popup == null) {
this.popup = this.createPopup(this.closeBox);
map.addPopup(this.popup);
this.popup.show();
} else {
this.popup.toggle();
}
OpenLayers.Event.stop(evt);
};
marker2.events.register("mousedown", feature, markerClick);
var marker3 = new OpenLayers.Marker(lonLat3);
var feature = new OpenLayers.Feature(markers, lonLat);
feature.closeBox = true;
feature.popupClass = OpenLayers.Class(OpenLayers.Popup.AnchoredBubble, { autoSize: true });
feature.data.popupContentHTML = '<p>Marker 3<p>';
feature.data.overflow = "hidden";
marker3.feature = feature;
var markerClick = function (evt) {
if (this.popup == null) {
this.popup = this.createPopup(this.closeBox);
map.addPopup(this.popup);
this.popup.show();
} else {
this.popup.toggle();
}
OpenLayers.Event.stop(evt);
};
marker3.events.register("mousedown", feature, markerClick);
markers.addMarker(marker1, icon1);
markers.addMarker(marker2, icon2);
markers.addMarker(marker3, icon3);
现在的问题是所有三个标记都有相同的图标... 有人可以帮我吗?
