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