class Heron.widgets.search.LocatieserverSearchCombo(config)

Create a ComboBox that provides a “search and zoom” function using OGC OpenLS XLS search. To use this class you need to include additional JS files in your page. See also the example HTML file under examples/namesearch.

#. If your map is not in EPSG:4326 (WGS84) you need to import Proj4JS, e.g. http://cdnjs.cloudflare.com/ajax/libs/proj4js/1.1.0/proj4js-compressed.js

1. You need a proxy server that should proxy the domain open.mapquestapi.com.

Example Use

Sample code showing how to include the Dutch national address (GEOZET, PDOK) search in your MapPanel toolbar.

Heron.layout = {
         xtype: 'hr_mappanel',

         hropts: {
                 layers: [
                         new OpenLayers.Layer.WMS( "World Map",
                           "http://tilecache.osgeo.org/wms-c/Basic.py?", {layers: 'basic', format: 'image/png' } )
                 ],
                toolbar : [
                        {type: "pan"},
