MooTools Link Fading

By  on  

We all know that we can set a different link color (among other properties) on the hover event, but why not show a little bit more dynamism by making the original color fade to the next? Using MooTools 1.2, you can achieve that effect.

The MooTools JavaScript

window.addEvent('domready',function() {
	$each($$('.fade'), function(el) {
		var original = el.getStyle('color');
		var morph = new Fx.Morph(el,{ 'duration':'300', link:'cancel' });
			'mouseenter' : function() { morph.start({ 'color':'#ff8c00' }) },
			'mouseleave' : function() { morph.start({ 'color': original }) }

For every link with the fade class, a transition occurs on the mouseenter and mouseleave events. You'll place the "to" color in the spot designated in comments in the code above.

What are your thoughts on this? Too much? Just right? Let me know!

  1. Kinda cool, and could work in the right application. It’s always worth remembering what the users expects from a link though.

    Unfortunately events don’t finish if a new one is fired right now, so the links can become locked to their active colour until the mouse enters again.

  2. thats why i’m using mootools, thanks for the great idea, i’m looking to integrate it in my blog… ^^

    I agree with Paul, there’s a problem with effects starting and ending.
    Here is my solution, 100% mootools-sugar!

    $$('.fade').set('morph', {'duration': '300'}).addEvents({
        'mouseenter': function(){
            if(!this.retrieve('original')){'original', this.getStyle('color'));}
            this.morph({'color': '#ff8c00'});
        'mouseleave': function(){
            this.morph({'color': this.retrieve('original')});
  4. @thomasd: I’ll try that sometime today! Thanks for contributing!

  5. norpius

    the problem can be resolved simply like this:

    var morph = new Fx.Morph(el,{ 'duration':'300', link: 'cancel' });
  6. @norpius: Yep, just got that a few minutes ago.

  7. Hmm.. I thought Fx.Tween is enough for this..

    Man, you’re F A N T A S T I C !

  9. Why not use addClass()?

    Hey one more cool script :)

    Thanks man!

    One quick question: How can I replace the “Color” with “Background Image” ?
    I tired but it ain’t working :(

    Any help would be appreciated!

  13. stefan

    Speed, Stefan, did you find the way to morph a photo by an other one ?

    What should I do to make it get the target color value from a specified css class instead of hard-coding it in the script as above?

    I had a special class written to do it in 1.11, but it doesn’t work under 1.2.1. I’ve already received some feedback and I guess I can fix it, but that person suggested me using fx.morph, but looking at the given example I can’t really figure out how.

    Thanks in advance,
    Kind regards,

  16. Hello,

    I’m trying to write a link fading plugin for Joomla but i cant get it to work because Joomla uses Mootools 1.11
    It seems mootools 1.11 doesnt know $each and Fx.morph
    Do you have any advice how to get this to work with mootools 1.11?

    Thank you!

  17. johan

    Looks very sweet & simple and will deff. try this out. :)
    But …
    I would like only the underlines to fade, not the letters is this possible?
    If so, how?

  18. I think this should work:

    Set in the CSS: text-decoration: none; for .fade and text-decoration: none; border-bottom: #000 1px solid; for .fade:hover

    Then replace in the script color with border-bottom and replace #ff8c00 with #ff8c00 1px solid

    Adjust the color-codes and you’re done ;)

    Isn´t it possible to use the link fading with the email protection script? Both together doesn´t work. :(

  20. Hey, here’s code for MooTools 1.11 for menu in Joomla. Just assign ID in menu module configuration.

    window.addEvent('domready', function() {
    var list = $$('#mainmenu li a');
    var original;
        if ( element.parentNode != $('current')) {
            var fx = new Fx.Styles(element, {duration: 1000, wait: false, transition: Fx.Transitions.Sine.easeIn});
            original = element.getStyle('color');
            element.addEvent('mouseenter', function(){
                    //'opacity' : 1,
                    'color': '#333333'
            element.addEvent('mouseleave', function(){
                    //'opacity' : 0.8, 
                    'color': original
  21. man you are awesome… really helpd me!!!

  22. paps

    hi david
    great code and thanks a lot for all you make !!

    i use your script in a website with “opacity” and it work !

    window.addEvent('domready',function() {
    	$each($$('.fade'), function(el) {
    		var original = el.getStyle('opacity');
    		var morph = new Fx.Morph(el,{ 'duration':'100', link:'cancel'});
    			'mouseenter' : function() { morph.start({ 'opacity':0.5}) },
    			'mouseleave' : function() { morph.start({ 'opacity':original}) }

    but I would like my div with "opacity:0.5" when the page open, and when you click on the div, it stay on "opacity:original" (the link is on the same page with a function show/hide)
    Is that possible ?

    thanks for your answers, and excuse me for my poor english (I’m french :-))

    Hi, thanks the script, simple and easy to use, but I definitely miss one small one function for the active class, i could figure it out it should look like a kind like that:

    ‘mouseenter’ : function() { morph.start({ ‘color’:’#2727f9′ }) },
    ‘mouseleave’ : function() { morph.start({ ‘color’: original }) },
    ‘click’ : function() { morph.start({ ‘color’:’#FF0000′ }) }

    but on mouseleave the ‘click’ color should stay, anyone knows how?

    best regards

    • morphwarp

      the best way was only one clicked event is stored and overrides other actives with original color again
