Question

I have found a MooTools version of Nivoo Slider that (in theory) will work with our MooTools dropdown menu. However, the menu is using MooTools 1.2.x, and Nivoo is using 1.3.2 or 1.4.0. Every time I try and use both the menu and the slider, the menu stops working.

Are the versions of the MooTools framework not backward compatible?

Also, are these plugins compatible or is one overriding the other?

I don’t know enough about JS to correct my errors or rewrite the function call. Is there a good beginner’s tutorial for this?

window.addEvent('domready', function () {
    var menu = new UvumiDropdown('dropdown-demo');

    // initialize Nivoo-Slider
    new NivooSlider($('slider'), {
        directionNavHide: true,
        effect: 'wipeDown',
        interval: 1000
    });
}); 

---

In trying to convert without compatibility, here are instructions that I was not sure how to implement.

Instruction

:: Line of 1.2 code

$clear => use the native clearTimeout when using fn.delay, use clearInterval when using fn.periodical.

:: $clear(a.retrieve(‘closeDelay’))

myFn.create => Use the according functions like .pass, .bind, .delay, .periodical

:: this.createSubmenu(this.menu)

myFn.bind(this, [arg1, arg2, arg3]) => myFn.bind(this, arg1, arg2, arg3) OR myFn.pass([arg1, arg2, arg3], this)

:: this.domReady.bind(this)

$$ now only accepts a single selector, an array or arguments of elements

:: $$(b,b.getChildren(‘li’)

These instructions are with compatibility. I’m trying both.

myElement.get('tween', options); // WRONG
myElement.set('tween', options).get('tween'); // YES, INDEED.

:: this.menu.get(‘tag’)!=’ul’

:: this.menu.getElement(‘ul’)

Answer 1

OK I tested the UvumiDropdown latest build with mootools 1.4.x and it worked fine as long as I included a Mootools more build that includes Fx.Elements

Hope this helps
