[OpenLayers-Users] WFSGetFeatureInfo and OpenLayers.Popup.FramedCloud

[Gery .]

Hi Raffaele,

I think the WMS request is always sent. One idea could be that you add some if/else inside the current if loop or elseif to prevent sending the request, something like:

getfeatureinfo: function(event) {                if(event.features.length > 0) {if (url =! "something") {//statement here to prevent to be sent}else
                        map.addPopup(new OpenLayers.Popup.FramedCloud(                            "sostegno",                            map.getLonLatFromPixel(event.xy),                            null,                            event.text,                            null,                            true                        ));                    }                }            }
the above is untested, it's just one idea about it. Perhaps googling around will help you to find some more ideas, try in stackoverflow.com.

Hope this helps,

Gery

Raffaele, That is the way I prevent the popup from showing up when there are not any features.  I am not sure how to prevent the getfeatureinfo request from being made in that situation.  Someone with more experience than myself will need to address that issue.

Subject: Re: [OpenLayers-Users] WFSGetFeatureInfo and OpenLayers.Popup.FramedCloud It helps but the WMS request is sent anyway, but apart from that it doesn't workevent.features.length=0 but the popup doesn't show up Here is my code snippet getfeatureinfo: function(event) {                if(event.features.length > 0) {                        map.addPopup(new OpenLayers.Popup.FramedCloud(                            "sostegno",                            map.getLonLatFromPixel(event.xy),                            null,                            event.text,                            null,                            true                        ));                    }                }            }
