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) {
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();
