Hi,

Sorry for late reply. I have done what you said with "getfeatureinfo" + i,
when I click each time, there are one window for each query. 

But how can I open 1 window only when querying? I have 6 layers, and if I
turn on 6 layers, 6 windows come out when clicking on the map. Only 1
windows contains information but others are useless ("EMPTY" template in
MapServer). I want the required window comes out only and the "EMPTY"
template comes out when clicked coordinates have nothing.

I think I should write some more 'if' statements to make it work, but I have
no idea about how to do this. I tried to compare the layer's
coordinates/pixels with e.xy.x and e.xy.y, so window comes out only when
they are same. But it fails, maybe I get the layer's coordinates wrongly. I
also tried to make mslayers[i] in ("&QUERY_LAYERS=" + mslayers[i]) in which
window comes out when mslayers[i] is not empty template, but fails too.

I got your second approach idea. But is that using WMSfeaturegetinfo or my
method? And it sounds like giving all queryable layers' information within
one window only, right?

Thanks
