AjxCallback(obj, func, args)

Author: Conrad Damon

run

Object run()

Runs the callback function, from within the object if there is one. The called function passed arguments are the concatenation of the argument array passed to this object's constructor and the argument array passed to the run method. Whatever the called function returns is returned to the caller.

Parameters:
arg1 - The first argument which will be appended to the argument array passed to this object's constructor. Any number of arguments may be passed to the run method.

toString

Object toString()

simpleClosure

<static> Object simpleClosure(func, obj)

The following function is what an AjxCallback should be *all* about. It returns a plain function that will call your supplied "func" in the context of "obj" and pass to it, in this order, any additional arguments that you pass to simpleClosure and the arguments that were passed to it at the call time. An example should do: div.onclick = AjxCallback.simpleClosure(this.handler, this, "some data"); ... this.handler = function(data, event) { // event will be passed for DOM2 compliant browsers // and data is "some data" }; [this is one of the most useful functions I ever wrote :D -mihai
