[maplab-users] Refresh of the map with query button

[Paolo]

Paul,
problem solved.
Using input_coords from document.forms[0].INPUT_COORD.value
and bbox from document.forms[0].PrevStateKey.value I built the string to
pass to query.html.
Here is javascript function (not so optimized..)

<script language="Javascript">
function init()
{
//layer to query
var layer = document.cf.layer.value;
if (layer = "")
{
alert ("Select one layer to query.....");
return false;
}
var bbox = document.forms[0].PrevStateKey.value;
var strCoord = document.forms[0].INPUT_COORD.value;
var length = strCoord.length;
var virg = strCoord.lastIndexOf(",", length);
strCoordX = strCoord.substr(0, virg);
strCoordY = strCoord.substring(virg+1, length);
var url = "http://192.168.1.1/path/query.phtml?PrevStateKey=" + bbox +
"&INPUT_COORD=" + strCoordX + "," + strCoordY + "&STRATO=" +
document.cf.layer.value;
if (document.all)
var xMax = screen.width, yMax = screen.height;
else if (document.layers)
var xMax = window.outerWidth, yMax = window.outerHeight;
else
var xMax = 640, yMax=480;
var xOffset = (xMax - 510)/2, yOffset = (yMax - 390)/2;
mapquery =
window.open(url,'mapquery','scrollbars=yes,resizable=yes,width=650,height=30
0,screenX='+xOffset+',screenY='+yOffset+',top='+yOffset+',left='+xOffset+'')
;
mapquery.focus();
}
</script>

It's ok for me but it queries only one layer and, at the moment, doesn't
check visible layers or layers with template.

Thank You very much

Paolo
