我有一個openlayers地圖，標記添加爲幾何矢量點。在樣式選項中，我爲每個選項設置一個大小。但是，問題是，如果我放大或縮小，它們都會變成相同的大小，直到我再次加載整個頁面。換句話說，一旦我放大或縮小，它們都是一樣的。Openlayers標記大小
var layer_style = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
var style = OpenLayers.Util.extend({}, layer_style);
var pointLayer = new OpenLayers.Layer.Vector("Point Layer");
map.addLayers([terrain, road, satellite, hybrid, pointLayer]);
var lonlat = new OpenLayers.LonLat(0, 140);
lonlat.transform(proj, map.getProjectionObject());
map.setCenter(lonlat, 2);
var point = new OpenLayers.Geometry.Point(-40, -40);
point = point.transform(proj, map.getProjectionObject());
style.pointRadius = 10;
var pointFeature = new OpenLayers.Feature.Vector(point, null, style);
pointLayer.addFeatures([pointFeature]);
var point = new OpenLayers.Geometry.Point(-40, -40);
point = point.transform(proj, map.getProjectionObject());
style.pointRadius = 40;
var pointFeature = new OpenLayers.Feature.Vector(point, null, style);
pointLayer.addFeatures([pointFeature]);
當我打開這個，我得到兩個標誌，一個大小爲10，其他40但當我放大或縮小，都成爲相同的大小。
