Arnd Wippermann,
Thanks for your answer. I get your idea, but it does not work.
It said "map.getLayersBy(...) is null or not an object.
I want to ask in [map.getLayersBy("name", "querylayer")[0].visibility], what
is the "name"?
If I create a layer like that:
var ABC_layer = new OpenLayers.Layer.MapServer( "ABC WMS",
"http://localhost/cgi-bin/mapserv.exe?map=c:/ms4w/Apache/htdocs/map.map&",
{layers: 'ABC'} );
The "name" is ABC WMS, ABC or ABC_layer?
Actually I have written in this way:
.....function (e) {
if (ABC_layer.visibility == true) {
var url.....
It works but this part of codes only for one layer only. If there are many
layers, the html file would be looked clumsy.
Thanks,
Aypes
