[OpenLayers-Users] Zoom to feature and highlight it

[Lee Meilleur]

Ken,

I'm a newbie with openlayers, but below is a snippet of the javascript I'm working on.   One problem is that I cannot control the zooming/panning after selecting and zooming to the feature.  The options are basically frozen.  That and it actually zooms in closer than the boundary of the selected feature.  Does anyone have any thoughts on why this happening?

Thanks,

Lee


<script type="text/javascript">
var map, layer;

function init(){
    var options = {
    projection: new OpenLayers.Projection("EPSG:26915"),
    maxExtent: new OpenLayers.Bounds(155791.714648, 4720323.238005, 794359.124023, 5570749.155271),
    maxResolution: "auto",
    numZoomLevels: 20,
    units: 'm'
    };
    map = new OpenLayers.Map( 'map', options );
    layer = new OpenLayers.Layer.MapServer( "Test Map", "http://localhost/cgi-bin/mapserv",
    {map: '/OpenLayers/mapfiles/test.map',
    mode: 'itemquerymap',
    qstring: "(name = 'SomeValue')",
    qlayer: 'layername',
    mapxy: 'shape'},
    {singleTile: true} );
    map.addLayer(layer);
    map.zoomToMaxExtent();
    }

    </script>

Subject: [OpenLayers-Users] Zoom to feature and highlight it



Here is what I'm trying to do.
I have google maps as my base layer.  Then I have a polygon layer on top of that. What I'm trying to do is link to a particular polygon and highlight it via a hyperlink somewhere on my website.

For example I would have a link similar to http://mywebsite/map.html/polygonIDNumber/

That would then open the map and zoom to and highlight the polygon that is identified in the URL. I've look at several example and I can't find what I'm looking for. Any help would be appreciated.
