I am doing a map which refresh dinamically all markers when they get modified. I want to add popups to show some info.

I create popups this way:

        var feature = new OpenLayers.Feature(markers, location); //location = lonlat
        feature.closeBox = true;
        feature.popupClass = OpenLayers.Class(OpenLayers.Popup.FramedCloud, {
        'autoSize': true
        feature.data.popupContentHTML = "info"; 
        feature.data.overflow = (false) ? "auto" : "hidden";        
            var markerClick = function (evt) {
            if (this.popup == null) {
                this.popup = this.createPopup(this.closeBox);
            } else {
            currentPopup = this.popup;
        mark.events.register("mousedown", feature, markerClick);

Now, I have the problem about what to do if one of my markers update its info. How can I destroy the popup? (I will create other one) or how can I modifiy it? Can I access them using lonlat?

Sometimes, I want to delete all of them, is there a way to do that? like deleting a layer or something?


for getting one popup info, you should do this:

map.popups[0]; // the firstly added popup

for removing one popup:

map.removePopup(map.popups[0]); // it will destroy firstly added popup
map.popups[0].destroy() // the same thing

for removing all popup from maps:

var pops = map.popups;
for(var a = 0; a < pops.length; a++){

for hiding and showing popups:


for finding popups from lonlat, you can get info for looping it in for loop and if clause:


and you can get the last popup with following code:


this all information is some part of Openlayers popup element...there are lots of thing you can do with popups...

i hope it helps you


Did you take a look at the OpenLayers.Map documentation? All popups are accessible from the "map" variable.

    it would be better if you could explain the answer rather than just providing a link
