[fusion-users] Get layer name from Legend right-click

[Mike Adair]

Tom,

Then your getRasterQuery method would look like:

function getRasterQuery(layer) {
    var temp = layer.name;
...
}

For the OpenLayers.Function.bind method, the first arg is the method to 
be bound, the second arg is the object to bind to (object will be 'this' 
inside the method), and then the rest of the arguments will be passed to 
the bound method as arguments.
