Javascript function hooks

Question

EDIT: OK, I believe the following solutions are valid:

1. Use the jQuery AOP plugin. It basically wraps the old function together with the hook into a function

Answer 1

Here's what I did, might be useful in other applications like this:

//Setup a hooking object
a={
    hook:function(name,f){
        aion.hooks[name]=f;
    }
}a.hooks={
    //default hooks (also sets the object)
}; 

//Add a hook
a.hook('test',function(){
    alert('test');
});

//Apply each Hook (can be done with for)
$.each(a.hooks,function(index,f){
    f();
});
