I have about 10 or more WMS layers that I'm adding to the map. I'm using
GetFeatureInfo to get values for each layer. So I have 10 of these:
------------------------------------------------------------------------------
map.events.register('click', map, function (e) {
if (map.layers[layer_index].visibility==true) {
var params = { REQUEST: "GetFeatureInfo",
EXCEPTIONS:
"application/vnd.ogc.se_xml",
BBOX: map.getExtent().toBBOX(),
X: e.xy.x,
Y: e.xy.y,
INFO_FORMAT: 'text/html',
QUERY_LAYERS:
map.layers[layer_index].params.LAYERS,
FEATURE_COUNT: 50,
Styles: '',
Layers: layer_name,
srs: 'EPSG:900913',
WIDTH: map.size.w,
HEIGHT: map.size.h,
format: 'image/png' };
event = e;
OpenLayers.loadURL("http://app-serv-01-uat/geoserver/wms";,
params, this,
setHTML, setHTML);
}
OpenLayers.Event.stop(e);
});
------------------------------------------------------------------------------
And since I have 10 of those for each of the 10 different layers, my code is
getting too long, messy and unmanageable. I tried to refactor it by creating
a for loop:
------------------------------------------------------------------------------
var layers_names = new
Array('sde:forests','sde:lakes','sde:trails,'sde:boundary','sde:buffallo','sde:fish','sde:birds','sde:picnic_sites','sde:rivers','sde:camping');
var layer_indices = new Array(5,6,7,8,9,10,11,12,13,14);
var layer_name;
var layer_index;
for (var i=0; i<layers_names.length; i++) {
layer_name = layers_names[i];
layer_index = layer_indices[i];
alert(layer_name+" "+layer_index);
map.events.register('click', map, function (e) {
if (map.layers[layer_index].visibility==true) {
var params = { REQUEST: "GetFeatureInfo",
EXCEPTIONS:
"application/vnd.ogc.se_xml",
BBOX: map.getExtent().toBBOX(),
X: e.xy.x,
Y: e.xy.y,
INFO_FORMAT: 'text/html',
QUERY_LAYERS:
map.layers[layer_index].params.LAYERS,
FEATURE_COUNT: 50,
Styles: '',
Layers: layer_name,
srs: 'EPSG:900913',
WIDTH: map.size.w,
HEIGHT: map.size.h,
format: 'image/png' };
event = e;
OpenLayers.loadURL("http://app-serv-01-uat/geoserver/wms";, params, this,
setHTML, setHTML);
}
OpenLayers.Event.stop(e);
});
}
------------------------------------------------------------------------------
My problem with this is that the click event sticks to the last array value
only. In this example, the GetFeatureInfo will only be fired on layer 12,
'sde:camping'. For the rest of the previous layers, it won't fire at all. I
might be missing something, so can someone help me out? Thank you very much.
