Zoom to Query

["William Bronsema" <wbronsema (at) dmsolutions.ca>]

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
