David, thanks for the reply, I guess you could say it was hidden. I posted
this<http://gis.stackexchange.com/questions/48522/geoserver-callback-function-undefinded>question
on gis.stackexchange and received a working solution. The .ajax()
call used the "success:" setting to call on the needed function. I'm
obviously new to JavaScript, especially anything ajax. I've got it working
but my method of creating the url seems a bit crude. Is there a more
efficient method than the following:
rootUrl = "
http://geoserver.capecodgis.com/geoserver/capecodgis/ows?service=WFS&version=1.0.0&request=GetFeature&;
typeName=capecodgis:cape_parcels_4326";
thisBbox = '&bbox=' + map.getBounds().toBBoxString();
maxFeatures = "&maxFeatures=300"
theRest = "&outputFormat=json&format_options=callback:getJson"
thisUrl = rootUrl + thisBbox + maxFeatures + theRest
$.ajax({
url : thisUrl,
dataType : 'jsonp',
jsonpCallback : 'getJson',
success : handleJson,
});
