Hi, "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?"
It use your method and it will only open one window. But if there is no result for all queried layers, the window open nevertheless. If you want to control the response from your request, you have to use an ajax call. Then you get back the response as text and if it's not empty, you show the response in a window.

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?
