I tried that, heres my complete funktion:
function checkinfo(imgid,url,title){
if (infobox == 0) {infobox = 1;}
if (imgid == oldimgid) {infobox = 0;}
id = imgid.substring(3,imgid.length);
if(infobox == 1 && document.getElementById(id).checked==true) {
document.getElementById('map').style.cursor = 'crosshair';
document.getElementById(imgid).src = "img/treemenu/identify_2.gif";
if (oldimgid != null) document.getElementById(oldimgid).src =
"img/treemenu/identify_1.gif";
oldimgid = imgid;
document.getElementById('nodeList').style.visibility = 'visible';
map.events.register('click', map, function (e) {
if(infobox == 1 && document.getElementById(id).checked==true) {
document.getElementById('map').style.cursor = 'crosshair';
OpenLayers.Util.getElement('nodeList').innerHTML = "Loading...
please wait...";
var coords = window[id].map.getLonLatFromPixel(e.xy.x, e.xy.y);
var request = window[id].getFullRequestString({
q_type: "0",
extent: window[id].map.getExtent().toBBOX(),
coords: coords.lon+","+coord.lat,
},
"http://172.21.18.45/ka-map/map_query_float.php?map=geoland_test&groups=Abflussstation");
OpenLayers.loadURL(request, '', this, setHTML);
OpenLayers.Event.stop(e);
}
});
}
else {
document.getElementById('map').style.cursor = 'auto';
document.getElementById('nodeList').style.visibility = 'hidden';
if (imgid == oldimgid) { oldimgid = null; } else { oldimgid = imgid;
}
document.getElementById('nodeList').innerHTML = "";
infobox = 0;
document.getElementById(imgid).src = "img/treemenu/identify_1.gif";
}
}
function setHTML(response) {
OpenLayers.Util.getElement('nodeList').innerHTML = response.responseText;
}
---------
but now i get:
coord is not defined
[Break on this error] coords: coords.lon+","+coord.lat,
