[OpenLayers-Dev] Get lat/lon from user click?

[Rodolfo Barriga]

you can create a custom openlayer control ... something like this



OpenLayers.Control.
ClickLayerInfo = OpenLayers.Class(OpenLayers.Control, {
    defaultHandlerOptions: {
        'single': true,
        'double': false,
        'pixelTolerance': 0, //tolarance
        'stopSingle': false,
        'stopDouble': false
    },
    initialize: function(options) {
        this.handlerOptions = OpenLayers.Util.extend(
            {}, this.defaultHandlerOptions
        );
        OpenLayers.Control.prototype.initialize.apply(
            this, arguments
        );
        this.handler = new OpenLayers.Handler.Click(
            this, {
                'click': this.trigger
            }, this.handlerOptions
        );
    },
    trigger: function(e) {
        var lonLat = you_map.getLonLatFromViewPortPx(e.xy);

        // you cant transform you lat and lon
        // you can def a pixel buffer with the map resolution
        // you can do a asyn call
    }
});

its work for me !! :-)
