Hi all,
I have a problem.
I need an expression to limit queries only to the layers that are visible at
that time on the map.
Queries are displayed via a popup.
The code where queries are made and displayed in the popup is as follows:
var showInfo = function(event) {
var pixel = event.xy;
var lonlat = this.getLonLatFromPixel(pixel);
var message = null;
var params = {};
params['service'] = 'wms';
params['request'] = 'GetFeatureInfo';
params['version'] = '1.1.1';
params['info_format'] = 'text/plain';
params['srs'] = this.getProjection();
params['bbox'] = this.getExtent().toBBOX(6);
params['width'] = this.getSize().w;
params['height'] = this.getSize().h;
params['feature_count'] = 1;
params['x'] = pixel.x; .
params['y'] = pixel.y;
params['layers'] = 'camino';
params['query_layers'] = 'camino';
new OpenLayers.Request.GET({
url: server,
async: false,
params: params,
success: function(data) {
message = data.responseText;
}
});
message = getHTML(message);
var popup = new OpenLayers.Popup.FramedCloud('popup', lonlat,
null, message, null, true, null);
this.addPopup(popup);
};//End of function showInfo()
map.events.register('click', map, showInfo);
