Openlayers zoomtoextent缩放到另一个位置

Question

我想放大EPSG：3857投影的地图上的边界框。地图应该放大到这里的某个地方：

https://www.google.co.il/maps/place/Netanya/@32.3047285,34.860532,12z/data=!3m1!4b1!4m2!3m1!1s0x151d400493c075d5:0x2cd995be543c3f22，但是将下面的代码放到非洲附近海域的某个地方。你能让我知道什么是错的吗？

bounds = new OpenLayers.Bounds(); 
 
bounds.extend(new OpenLayers.LonLat(34.8660822,32.3172887)); 
 
bounds.extend(new OpenLayers.LonLat(34.8570271,32.2953077)); 
 
bounds.toBBOX(); 
 
map.openlayers.zoomToExtent(bounds); 
 
map.openlayers.updateSize();

Answer 1

你必须从EPSG改变你的边界：4326（WGS84）到EPSG：900913（EPSG：3857）

bounds = new OpenLayers.Bounds(); 
bounds.extend(new OpenLayers.LonLat(34.8660822,32.3172887)); 
bounds.extend(new OpenLayers.LonLat(34.8570271,32.2953077)); 
bounds.transform(new OpenLayers.Projection("EPSG:4326"), new OpenLayers.Projection("EPSG:900913")); 
map.openlayers.zoomToExtent(bounds, true);
