[OpenLayers-Users] Beforegetfeatureinfo and getfeatureinfo

[Bart van den Eijnden]

Hi Luca,

no this is not possible currently, please file an enhancement ticket (patches welcome ofcourse).

A workaround you can try is something like (untested pseudo code):

var findLayers = control.findLayers;
control.events.on({
    beforegetfeatureinfo: function(evt) {
        if // do your zoom level check here {
            control.findLayers = function() {
                return [];
           };
        } else {
            control.findLayers = findLayers;
        }
    }
});

Best regards,
Bart
