Accept arrays of arguments via rbind

Actually, this would be nice for other functions in MochiKit.DOM currently accepting an element (or an id of one) - the ability to accept (recursive) arrays of elements (or id's).

The following functions seem logical to change to this:

• MochiKit.DOM.setNodeAttribute
• MochiKit.DOM.getNodeAttribute
• MochiKit.DOM.removeElementClass
• MochiKit.DOM.addElementClass

It could probably not be used for hasElementClass - return value would be ambiguous (does it return an array or a boolean literal as a conjunction of results?). swapElementClass and toggleElementClass might also be interesting, but I'm not sure.

All functions only accepting a single node as argument could easily be called with map, so no change here is needed.

Thanks.

The above comment was also by me - sorry :)

Okay, this was to funny to not implement. I've now started functions like getNodeAttribute as:

    getNodeAttribute: function (node, attr) {
        var self = MochiKit.DOM;
                var base = MochiKit.Base;
                if (base.isArrayLike(node))
                        return base.map(base.rpartial(self.getNodeAttribute, attr), node);
        if (base.isArrayLike(attr))
                        return base.map(base.partial(self.getNodeAttribute, node), attr);

In order for this to work, I had to create the rpartial. And the I had to create the rbind. And then I was copying code from bind, which seemed like a bad solution. So instead I created an internal function, _bind, as:

    _bind: function (func, self, preargs, postargs) {

That simply contains what bind contained before with the addition of remembering, updating and using postargs as well as preargs. And then bind and rbind is:

        /** @id MochiKit.Base.bind */
    bind: function (func, self/* args... */) {
        var m = MochiKit.Base;
        return m._bind(func, self, m.extend(null,arguments,2), []);
        },
        
        /** @id MochiKit.Base.rbind */
    rbind: function (func, self/* args... */) {
        var m = MochiKit.Base;
        return m._bind(func, self, [], m.extend(null,arguments,2));
        },

I've also added a bunch of testcase for rpartial and for partial and rpartial together. It works perfectly.

How do I go about suggesting a patch? I downloaded HEAD (revision 1269) and have created a patch attached here.
