[OpenLayers-Users] searching a feature with open layers

[Arnd Wippermann]

You can apply a filter to the WFS layer. 
WFSlayer.mergeNewParams({'filter' : yourFilter }); 

But this works only, if the filtered feature is visible in the current
extent of the map. If you know the centerpoint of the features, you can set
a new center for the map after applying the filter.

ter.html

Hi,

Thanks,
I would like to know , can I pass the value of an attribute (eg : In
top:states , can pass STATE_name ="texas')  instead of maxfeatures with
OpenLayers.Layer.WFS.
Thanks, .

Hi,

You can load your WFS with OpenLayers with option 'extractAttributes': true.


    //OpenLayers.ProxyHost for WFS needed!!!
    layerWFS = new OpenLayers.Layer.WFS( "WFS Titel", WFS_Url,
        {typename: "POLYGONS", maxfeatures: 500}, { typename: "POLYGONS",
extractAttributes: true});
 
Now you have access to the features geometry and the features attributes.

Mit freundlichen Grüssen
