[Chameleon] Zoom to query - how to set extents in

[scdyoung at tpg.com.au]

Hi again

Thanks Bill

It appears that I am having trouble setting the new extents via the $oMapSession->oMap->extents 
method in my query.phtml.  Naively (fingers crossed) I was making the assumption that by setting 
the params at this point things would propogate.   This is not the case, and  I'm guessing that I need 
to write to the savesessionpath or something along those lines ?  is there some other application 
variable I might be able to set, and if so how ? or am I going about this the wrong way ? (learning 
quite a bit I might add!) 


Regards

Dale


Hi Dale,

To just refresh the map image without submitting the page, I use a simple
JavaScript function in my template and call it when necessary:

function redrawMap()
{
    var img = CWCDHTML_GetImage( 'MapLayerDivImg' );
    img.src = gMapDHTMLURL + "&ts="+Math.random();
}

HTH,
Bill
