Right, the constructor for the Scale Control is a bit different:
/**
* Constructor: OpenLayers.Control.Scale
*
* Parameters:
* element - {DOMElement}
* options - {Object}
*/
initialize: function(element, options) {
OpenLayers.Control.prototype.initialize.apply(this, [options]);
this.element = OpenLayers.Util.getElement(element);
},
So try:
new OpenLayers.Scale(document.getElementById("scale"))
I'll file a bug so we fix this up in 3.0. Thanks for the report.
