[OpenLayers-Users] Map controls properties

[Paul Spencer]

can you not just make 'query' a global variable and reference directly?

var query;

window.onload = function() {
   query = ...
}

function toggleQuery() {
   if (this.value == 'query') {
     query.activate();
   } else {
     query.deactivate();
   }
}
