As reported to the users list by Brian K (and corroborated ((in IE6)) by 'Donal'):
I implemented the click example(click.html) to capture the position of the click and place a marker there. I only want it to do this on a single click, but it is also being called at the end of a pan upon mouseup and also when I click on the zoom bar anywhere in between + and -. Is there anyway to disable the click event during these actions?
Here is the code where the click event is being registered:
function initializeMapStart(Lon, Lat, Zoom)
{
layerData.maxExtent = new OpenLayers.Bounds(-94.807800, 35.638191, -94.472656, 36.161896);
var options =
{
'controls':[],
'maxExtent': layerData.maxExtent,
'maxResolution': 'auto',
scales: [2000000, 1000000, 500000, 250000, 125000, 62500, 31250, 15625, 7812, 3906, 1953],
projection: 'EPSG:4326',
'tileSize': new OpenLayers.Size(200, 200)
};
openLayersMap = new OpenLayers.Map('mapDiv', options);
OpenLayers.Util.onImageLoadErrorColor = null;
//Base layer
layer = new OpenLayers.Layer.KaMap('basemap',
kamapUrl,
{
'map': 'oklahoma',
'g': 'all',
'i': 'gif'
},
{
'buffer': 1
}
);
layer.displayOutsideMaxExtent = true;
openLayersMap.addLayer(layer);
//Marker layer
var markersLayer = new OpenLayers.Layer.Markers("Locate");
if (Lon != 0.0 && Lat != 0.0)
{
var marker = new OpenLayers.Marker(new OpenLayers.LonLat(Lon, Lat), new OpenLayers.Icon("http://kormap/MapService/Images/okiemarker.png", new OpenLayers.Size(30,60)));
markersLayer.addMarker(marker);
openLayersMap.addLayer(markersLayer);
var markerbounds = new OpenLayers.Bounds(Lon, Lat, Lon, Lat);
var newLonLat = markerbounds.getCenterLonLat();
openLayersMap.setCenter(newLonLat, Zoom);
}
if (Zoom == 0)
zoomToExtent(markerbounds);
THE CLICK EVENT
openLayersMap.events.register("click", openLayersMap, function(e)
{
markersLayer.clearMarkers();
var lonlat = openLayersMap.getLonLatFromViewPortPx(e.xy);
var marker = new OpenLayers.Marker(new OpenLayers.LonLat(lonlat.lon, lonlat.lat), new OpenLayers.Icon("http://kormap/MapService/Images/okiemarker.png", new OpenLayers.Size(30,60)));
// alert("You clicked " + lonlat.lon + ", " + lonlat.lat);
markersLayer.addMarker(marker);
openLayersMap.addLayer(markersLayer);
document.forms[0].txtLatitude.value = lonlat.lat;
document.forms[0].txtLongitude.value = lonlat.lon;
});
