Question

What does dijit.registry.remove() do? How does it handle invalid parameters?

Answer 1

The dijit.registry reference is an instance of dijit.WidgetSet, which is a collection of widgets.

The remove() function accepts an input ID and removes that Widget with the corresponding ID from the collection, if found.

In Dojo 1.4, WidgetSet is defined within dijit/_base/manager.js.

The passed ID is used internally as the key looked in an associative array. It's used like: this._hash[id], so passing it garbage will result in nothing being found or removed.
