[OpenLayers-Users] referencing controls by name

[Graham Davis]

I had a similar problem and needed to access specific controls (I 
couldn't gurantee to know what order they were in the map controls 
array).  I achieved this by creating the controls and assigning them to 
global JS variables.  Something like this:

// global vars
var layer_control;

function init() {
  
  <do map creation and init here>
 
  // add controls
  layer_control = new OpenLayers.Control.LayerSwitcher();
  map.addControl(layer_control);
  ...
}

Then anywhere in your JS code you can call layer_control as your control 
object.
