- // summary:
- // `dojo.connect` is the core event handling and delegation method in
- // Dojo. It allows one function to "listen in" on the execution of
- // any other, triggering the second whenever the first is called. Many
- // listeners may be attached to a function, and source functions may
- // be either regular function calls or DOM events.
- //
- // description:
- // Connects listeners to actions, so that after event fires, a
- // listener is called with the same arguments passed to the original
- // function.
- //
- // Since `dojo.connect` allows the source of events to be either a
- // "regular" JavaScript function or a DOM event, it provides a uniform
- // interface for listening to all the types of events that an
- // application is likely to deal with though a single, unified
- // interface. DOM programmers may want to think of it as
- // "addEventListener for everything and anything".
- //
- // When setting up a connection, the `event` parameter must be a
- // string that is the name of the method/event to be listened for. If
- // `obj` is null, `dojo.global` is assumed, meaning that connections
- // to global methods are supported but also that you may inadvertently
- // connect to a global by passing an incorrect object name or invalid
- // reference.
- //
- // `dojo.connect` generally is forgiving. If you pass the name of a
- // function or method that does not yet exist on `obj`, connect will
- // not fail, but will instead set up a stub method. Similarly, null
- // arguments may simply be omitted such that fewer than 4 arguments
- // may be required to set up a connection See the examples for details.
- //
- // The return value is a handle that is needed to
- // remove this connection with `dojo.disconnect`.
- //
- // obj:
- // The source object for the event function.
- // Defaults to `dojo.global` if null.
- // If obj is a DOM node, the connection is delegated
- // to the DOM event manager (unless dontFix is true).
- //
- // event:
- // String name of the event function in obj.
- // I.e. identifies a property `obj[event]`.
- //
- // context:
- // The object that method will receive as "this".
- //
- // If context is null and method is a function, then method
- // inherits the context of event.
- //
- // If method is a string then context must be the source
- // object object for method (context[method]). If context is null,
- // dojo.global is used.
- //
- // method:
- // A function reference, or name of a function in context.
- // The function identified by method fires after event does.
- // method receives the same arguments as the event.
- // See context argument comments for information on method's scope.
- //
- // dontFix:
- // If obj is a DOM node, set dontFix to true to prevent delegation
- // of this connection to the DOM event manager.
- //
- // example:
- // When obj.onchange(), do ui.update():
- // | dojo.connect(obj, "onchange", ui, "update");
- // | dojo.connect(obj, "onchange", ui, ui.update); // same
- //
- // example:
- // Using return value for disconnect:
- // | var link = dojo.connect(obj, "onchange", ui, "update");
- // | ...
- // | dojo.disconnect(link);
- //
- // example:
- // When onglobalevent executes, watcher.handler is invoked:
- // | dojo.connect(null, "onglobalevent", watcher, "handler");
- //
- // example:
- // When ob.onCustomEvent executes, customEventHandler is invoked:
- // | dojo.connect(ob, "onCustomEvent", null, "customEventHandler");
- // | dojo.connect(ob, "onCustomEvent", "customEventHandler"); // same
- //
- // example:
- // When ob.onCustomEvent executes, customEventHandler is invoked
- // with the same scope (this):
- // | dojo.connect(ob, "onCustomEvent", null, customEventHandler);
- // | dojo.connect(ob, "onCustomEvent", customEventHandler); // same
- //
- // example:
- // When globalEvent executes, globalHandler is invoked
- // with the same scope (this):
- // | dojo.connect(null, "globalEvent", null, globalHandler);
- // | dojo.connect("globalEvent", globalHandler); // same

- // if a[0] is a String, obj was omitted
