This may be ugly but it does work.
att.item(1).value is the class of the polygon but I could not find a better way
to reference
it. chaine is url that will be posted to my server with the information on
which polygons
were selected and unselected.
Thanks for the suggestion.
Russ
function changeColor(evt) {
objet=evt.target;
att=objet.attributes;
var state = document.getElementById(att.item(0).value);
if (att.item(1).value == "selected")
{
att.item(1).value = "notselected";
oldcolor = att.item(3).value;
var style = state.style;
style.setProperty("fill",oldcolor, "");
chaine = chaine+'unfield='+ att.item(0).value +"&";
}
else
{
att.item(1).value = "selected";
var style = state.style;
style.setProperty("fill", "red", "");
chaine = chaine+'field='+ att.item(0).value +"&";
}}
