[OpenLayers-Users] Search possible with OpenLayers?

[Mapmaker]

Asle,

I have been able to accomplish basic search functionality using XML and
JavaScript based on the code here: http://snippets.dzone.com/posts/show/2719

Basically, I calculate the bounding box values (X_MAX, Y_MAX, XMIN, YMIN)
for every polygon feature in my layer and add that as an attribute in my
database.  Once I have the bounding coordinates, I can concatenate the
fields I want and build a javascript html link to zoom to the extents of the
feature- something like this:

<a href="javascript: map.zoomToExtent(new
OpenLayers.Bounds(-74.101606552,44.400644696,-73.273634891,45.039590722);"
target="_top">Zoom To</a>

Convert your attribute table with the link field to an XML file and use the
code from the above link to build your search box.  The search will return a
list of results with links to "Zoom To" the feature.

This works great with GeoServer because you can place everything in the
"www" folder and not have to worry about proxies or cross domain issues.

Best of luck!

BRYAN
