[英]OpenLayers.Layer.Text displays icons at 0,0
I'm using Text layer from OpenLayers 2.13.1 to display a list of points on the map. 我正在使用OpenLayers 2.13.1中的Text图层在地图上显示点列表。 The problem is that icons are always placed at point 0,0 (Gulf of Africa) instead of at their own positions. 问题在于,图标始终放置在0,0点(非洲海湾)上,而不是位于其自身位置上。
I tried also with OpenLayers.Marker but never changes. 我也尝试使用OpenLayers.Marker,但从未更改。
In both cases I just used examples on openlayers api docs. 在这两种情况下,我仅在openlayers api文档上使用了示例。
Here the code: 这里的代码:
// WIDGETS
var map, dragpan, toolbar;
// OPENLAYERS
var gmap;
var aMapLayers = [];
// MAP
var url = 'http://' + constants.ip + constants.geoserver;
var panZoom = new OpenLayers.Control.PanZoom();
panZoom.onButtonClick = function(evt) {
var btn = evt.buttonElement;
switch (btn.action) {
case 'panup':
this.map.pan(0, -this.getSlideFactor('h'));
break;
case 'pandown':
this.map.pan(0, this.getSlideFactor('h'));
break;
case 'panleft':
this.map.pan(-this.getSlideFactor('w'), 0);
break;
case 'panright':
this.map.pan(this.getSlideFactor('w'), 0);
break;
case 'zoomin':
this.map.zoomIn();
break;
case 'zoomout':
this.map.zoomOut();
break;
case 'zoomworld':
proj = new OpenLayers.Projection('EPSG:4326');
point = selectMarketMap();
map.setCenter(point.transform(proj, map.getProjectionObject()), 6);
break;
}
};
map = new OpenLayers.Map('map', {
div: 'map',
projection: 'EPSG:900913',
displayProjection: 'EPSG:4326',
controls: [panZoom, new OpenLayers.Control.Navigation()]
});
// PAN/DRAG CONTROLS
dragpan = new OpenLayers.Control.DragPan();
map.addControl(dragpan);
// LAYER GOOGLE MAPS
gmap = new OpenLayers.Layer.Google('Google Streets', {
numZoomLevels: 20
});
aMapLayers = [gmap];
var text = new OpenLayers.Layer.Text('text', {
location: './js/textfile.txt'
});
aMapLayers.push(text);
map.addLayers(aMapLayers);
map.addControl(new OpenLayers.Control.LayerSwitcher());
proj = new OpenLayers.Projection('EPSG:4326');
point = selectMarketMap();
map.setCenter(point.transform(proj, map.getProjectionObject()), 6);
Any help would be appreciated! 任何帮助,将不胜感激! Thanks 谢谢
Solved adding projection to text layer: 解决了将投影添加到文本层的问题:
var text = new OpenLayers.Layer.Text('text', {
location: './js/textfile.txt',
projection: map.displayProjection
});
