Thanks for your suggestion, I tried to use your suggested code but I am getting a Javascript error after hovering over my layer, which states -
Message: Unspecified error. Line: 1188 Char: 1 Code: 0 URI: http://localhost/WebServices/OpenLayers-2.10/OpenLayers.js which is this line in OpenLayers.js but not sure exactly what's wrong. I do appreciate your assistance. this._object.send(vData);if(bGecko&&!this._async){this.readyState=cXMLHttpRequest.OPENED;fSynchronizeValues(this);while(this.readyState<cXMLHttpRequest.DONE){this.readyState++;fReadyStateChange(this);if(this._aborted) var info, infopop; //Getfeatureinfo object info = new OpenLayers.Control.WMSGetFeatureInfo({ url: 'http://ITS701X5J1/RedWMS/Request.aspx', title: 'Identify features by clicking', layers: [layer_Garbage_Zones], queryVisible: true, infoFormat: 'text/html', maxFeatures: 1, hover:true }); info.events.on({ getfeatureinfo: function(e) { //get all existing popups var popups = Ext.WindowMgr.getBy(function(win){return (win instanceof GeoExt.Popup)}); //kill all existing popups popups.each(function(popup){popup.destroy()}); //<ADDED CODE - end> infopop = new GeoExt.Popup({ //utilizing the GeoExt popup functionality title: "Hotspot Information", autoWidth: true, autoHeight: true, autoScroll: false, map: map, lonlat: map.getLonLatFromPixel(e.xy), html: e.text }) etext = e.text; // if the hotspot information is empty (layer doesn't match) don't display! if (etext.length == 45) { infopop.close(); } else { infopop.show(); } }}); map.addControl(info); info.activate(); ________________________________ From: Matt Priour [mailto:[email protected]] Sent: September 20, 2010 1:39 PM To: Andrew Stewart; [email protected] Subject: Re: [Users] GeoExt Popup / GetFeatureInfo, how do I destroy the popup if it exists?

Below is my code for when I hover over a specific layer and the popup hotspot information is shown. I am trying to figure out how to only get one popup to show at a time so that I can show them like tooltips and destroy the existing one if another is shown. I have tried using if (infopop) or if (!infopop) but this doesn't seem to work in the way I have this coded. If anyone has any advice on how to destroy my popup when another is created thanks! var info, infopop; //Getfeatureinfo object info = new OpenLayers.Control.WMSGetFeatureInfo({ url: 'http://ITS701X5J1/RedWMS/Request.aspx', title: 'Identify features by clicking', layers: [layer_Garbage_Zones], queryVisible: true, infoFormat: 'text/html', maxFeatures: 1, hover:true }); info.events.on({ getfeatureinfo: function(e) { <ADDED CODE - begin> //get all existing popups var popups = Ext.WindowMgr.getBy(function(win){return (win instanceof GeoExt.Popup)}); //kill all existing popups popups.each(function(popup){popup.destroy()}); <ADDED CODE - end> infopop = new GeoExt.Popup({ //utilizing the GeoExt popup functionality title: "Hotspot Information", //height: 215, //width: 600, autoWidth: true, autoHeight: true, autoScroll: false, // panIn: true, map: map, lonlat: map.getLonLatFromPixel(e.xy), html: e.text }) etext = e.text; // if the hotspot information is empty (layer doesn't match) don't display! if (etext.length == 45) { infopop.close(); } else { infopop.show(); } }}); map.addControl(info); info.activate(); ________________________________ This e-mail is intended for the original recipient(s) only.
