[OpenLayers-Users] getCapabilities

Tue Jun 11 08:24:32 PDT 2013

Hello again,

I’ve changed the code to someting like:

function init(){

var request = OpenLayers.Request.GET({

                url:
"http://geodaten.bayern.de/ogc/ogc_dop200_oa.cgi?service=WMS&request=GetCapa
bilities&version=1.1.1",

                 success: function(response){

                                var format = new
OpenLayers.Format.WMSCapabilities();

                                var xml = request.responseXML;

                               var capabilities = format.read(xml);

                               for (var i=0; i < capabilities.layers.length;
i++) {

                                               layer =
capabilities.layers[i];

alert(layer.name);

                               }

                }

                });

}

But that does not really improve things, so I guess that’s not what you’ve
meant- sorry I’m really new to OpenLayers.

Thanks again

Helmut

Betreff: Re: [OpenLayers-Users] getCapabilities

Your url is not a GetCapabilities request, use e.g.:

http://geodaten.bayern.de/ogc/ogc_dop200_oa.cgi?service=WMS
<http://geodaten.bayern.de/ogc/ogc_dop200_oa.cgi?service=WMS&request=GetCapa
bilities&version=1.1.1> &request=GetCapabilities&version=1.1.1

Also, you don't need the Format.XML in between, the code will handle that
for you, and use OpenLayers.Format.WMSCapabilities, the format will see what
the version is of the GetCapabilities output.

Best regards,

Bart

Hello everybody,

sorry - this could be a newby question:

I tryed the following code to retrive the capabilities of a wms-Layer:

<head>

<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />

                <title>getCapabilities Test</title>

                <script type="text/javascript"
src="OpenLayers/lib/OpenLayers.js"></script>

                <script type="text/javascript">

                               function init(){

                                               var request =
OpenLayers.Request.GET({

                url: " <http://geodaten.bayern.de/ogc/ogc_dop200_oa.cgi>
http://geodaten.bayern.de/ogc/ogc_dop200_oa.cgi",

            success: function(response){

                var format = new OpenLayers.Format.XML();

                var xml = format.read(response.responseText

                                               var CAPformat = new
OpenLayers.Format.WMSCapabilities.v1_1_1();

                                                               var cap =
CAPformat.read(xml);

                for (var i=0; i < cap.capability.layers.length; i++)

                                                               {

                               layer = cap.capability.layers[i];

alert(layer.name);

                                                               }

                                               }

                               });

                               }

                </script>

</head>

<body onload="init();">

</body>

Firebug tells me:

TypeError: cap.capability is undefined

for (var i=0; i < cap.capability.layers.length; i++)

I can't see whats wrong - can anybody help?

Thanks again
