[OpenLayers-Users] GetFeatureInfo on Single Click, Zoom In on Double Click

[jvanulde]

I managed to get it to work with the OpenLayers.Handler.Click as follows:

// create a new event handler for single click query
var clickEventHandler = new OpenLayers.Handler.Click({ 'map': map }, {
'click': function(e) { doQuery(e); } }); 

clickEventHandler.activate();

function doQuery(evt)
        {

            // get the active layerName from the custom layerSwitcher
property
            // which is set when a user clicks on the nameLabel

            var layerName = layerSwitcher.activeLayer;
            
            if(evt)
            {
                var activeLayer = map.getLayersBy("name", layerName); 
                
                if(activeLayer)
                {        
                    var url =   activeLayer.getFullRequestString({
                                REQUEST: "GetFeatureInfo",
                                EXCEPTIONS: "application/vnd.ogc.se_xml",
                                BBOX: activeLayer.map.getExtent().toBBOX(),
                                X: evt.xy.x,
                                Y: evt.xy.y,
                                INFO_FORMAT: 'text/html',
                                QUERY_LAYERS: activeLayer.params.LAYERS,
                                WIDTH: activeLayer.map.size.w,
                                HEIGHT: activeLayer.map.size.h});
                                
                    var popupWindow = window.open(url, "GetFeatureInfo",
"width=550,height=350,status=yes,scrollbars=yes,resizable=yes");
                    popupWindow.focus();
                    OpenLayers.Event.stop(evt);
                }
            }
        }

Note that I still have some issues with getting the layerName from the
layerSwitcher, so if you have any suggestions on how this can be improved
please let me know. 

Cheers,

Joost
