Mootools equivalent of jQuery toggle()?

Question

I'm using trying to use mootools for a quick task of toggling some text on click. But I can't seem to find a Mootools equivalent of jQuery's toggle() function.

What I'm trying to do is as follows:

$('a#id').toggle(
 function() {
  $(this).set('html', 'new text');
 },
 function() {
  $(this).set('html', 'old text');
 }
);

How would I modify the above code for mootools?

Thanks!

Answer 1

As far as I know that "toggle" on mootools doesn't exists.

You could "implement" it, by this way for example: http://www.jsfiddle.net/steweb/rdvx8/

Is this what you'd like to obtain?

Edit (for mootools developers :D ), this could be a way to create a general "toggle":

Element.implement({
    toggle: function(fn1,fn2){
        this.store('toggled',false);
        return this.addEvent('click',function(event){
            event.stop();
             if(this.retrieve('toggled')){
                 fn1.call(this);
             }else{
                 fn2.call(this);
             }
            this.store('toggled',!(this.retrieve('toggled')));
        });
    }
});

//using it in a 'jQuery' mode

$('mya').toggle(
   function() {
      this.set('html', 'new text');
   },
   function() {
      this.set('html', 'old text');
   }
);

Answer 2

i know you accepted the other answer but mootools 1.3 now provides an excellent new feature, Element Pseudos which I feel will be a good solution here. for starters, code below

http://www.jsfiddle.net/dimitar/VR9k8/4/

(function() {
    var toggled = 0;
    Event.definePseudo('toggle', function(split, funcsArray, args){
         if (funcsArray.length && funcsArray[toggled])
             funcsArray[toggled].apply(this, args); // args[0] is the Event instance

         toggled++;
         if (toggled >= funcsArray.length)
             toggled = 0;
     });
})();

document.id("foo").addEvent("click:toggle", [function(e) {
    e.stop();
    alert("function 1");
}, function(e) {
    e.stop();
    alert("function 2");
}, function(e) {
    e.stop();
    // event object (args[0])
    console.dir(e);
    alert("function 3");
}]);

...will allow you to daisy chain nn number of functions to loop-run consecutively as well as passing on arguments or at least the original event.
