I am new to mootools. I have joomla site with MooSlider:
var MooSlider = new Class({
initialize: function(options) {
this.options = Object.extend({
container: null,
slides: null,
navs:null,
transition: Fx.Transitions.Sine.easeOut,
effectDuration: 500,
fromTop: 500,
topDist: 100,
slideDelay: 5000
}, options || {});
if(!$(this.options.container)) return;
this.start();
},
start: function(){
this.elements = $(this.options.container).getElements(this.options.slides);
this.navs = $(this.options.container).getElements(this.options.navs);
this.currentElement = 0;
this.elements.each(function(elem, i){
var nav = this.navs[i];
if(i==this.currentElement){
nav.addClass('selected');
}
elem.setStyles({
'position':'absolute',
'top':0,
'left':0,
'opacity':( i==this.currentElement ? 1 : 0 )
});
this.elements[i]['fx'] = new Fx.Styles(elem, {
duration:this.options.effectDuration,
wait:false,
transition:this.options.transition
});
this.elements[i]['nav'] = nav;
elem.addEvents({
'mouseenter': function(){
$clear(this.period);
}.bind(this),
'mouseleave': function(){
if( this.options.slideDelay )
this.period = this.rotate.periodical(this.options.slideDelay, this);
}.bind(this)
});
nav.addEvent('click', function(event){
if(this.currentElement==i) return;
new Event(event).stop();
$clear(this.period);
this.changeSlide(i);
if( this.options.slideDelay )
this.period = this.rotate.periodical(this.options.slideDelay, this);
}.bind(this));
}.bind(this));
if( this.options.slideDelay )
this.period = this.rotate.periodical(this.options.slideDelay, this);
},
rotate: function(){
var i = this.currentElement+1 < this.elements.length ? this.currentElement+1 : 0;
this.changeSlide(i);
},
changeSlide: function(i){
//$(this.options.navigationContainer).addClass('preload');
var cEl = this.currentElement;
this.elements[this.currentElement]['fx'].start({'opacity':0, 'left':1500});
this.elements[i]['fx'].set({'left':0});
this.elements[i]['fx'].start({'opacity':1, 'top':[500,0]}).chain(function(){
//$(this.options.navigationContainer).removeClass('preload');
}.bind(this));
this.elements[this.currentElement]['nav'].removeClass('selected');
this.elements[i]['nav'].addClass('selected');
this.currentElement = i;
}})
This is how it used on page:
<script language="javascript" type="text/javascript">
window.addEvent('domready', function(){
new MooSlider({
container:'topslider',
slides:'.slide',
navs:'.navigator ul li',
effectDuration: 1000,
fromTop:500,
topDist:500,
slideDelay: 3000 });
})
The page url is http://www.miltonwebsitedesign.ca
You can see slider on top of the page. Each slide consists of picture at the left and description at the right.
What I need is to make slides work the same way, but the left side picture must not appear current way, it needs to fade in, when the slide is loaded, not appear, but fade in.
Description text slides and then at the left picture appears.
The structure of each slide is:
<div class='slide'>
<div class="yjsquare">
<div class="yjsquare_in">
<img src='src here' alt=''/><h1>H1 text here</h1><p>description here</p>
</div>
</div>
</div>
Will be happy to hear solution. Thanks.
this class is not well written as in, it does not allow for events like onStart and onComplete to be passed. the logical approach would be to modify the changeSlide method to fire some events:
// add
var el = this.elements[i]['fx'];
this.fireEvent("start", el);
// use el as reference...
el.start({'opacity':1, 'top':[500,0]}).chain(function(){
//$(this.options.navigationContainer).removeClass('preload');
// add
this.fireEvent("complete", el);
}.bind(this));
Make sure that your class also implements Events (which in 1.12 is done like so, if memory serves):
MooSlider.implement(new Events);
you are using a mix of 1.12 and 1.2+ code which is odd. In any case, if you do have 1.2 (joomla usually is not prior to 1.6) then instead add this into the class declaration:
Implements: [Events],
this allows you to add some callback logic upon instigating the class:
new MooSlider({
container:'topslider',
slides:'.slide',
navs:'.navigator ul li',
effectDuration: 1000,
fromTop:500,
topDist:500,
slideDelay: 3000,
onStart: function(el) {
el.getElement("img").setOpacity(0); // hide it during animation
},
onComplete: function(el) {
el.fade(1); // fade it in when done
}
});
you should really implement Options too and use this.setOptions(options) instead of your current $extend.
p.s. the onStart and onComplete code callbacks are examples, you may need to tweak this to suit your html and UI preferences.

I have a list where the first-child element is visible on desktop, and is hidden on screens under 767px, and then every other element cycles through on a loop for all screen sizes.
I have been trying to re-run this jQuery plugin on window resize without success, please could someone help implement window resize function?
I have put together an example here
(function ($){
$.fn.extend({
rotaterator: function(options) {
var defaults = {
fadeSpeed: 500,
pauseSpeed: 100,
child:null
};
var options = $.extend(defaults, options);
return this.each(function() {
var o =options;
var obj = $(this);
var obj2 = "ul li:first-child";
var items = $(obj.children(), obj);
var items2 = $(obj.children(), obj2);
if ($(window).width() < 767) {
items.each(function() {$(this).hide();})
items2.each(function() {$(obj2).hide();})
} else {
items.each(function() {$(this).hide();})
items2.each(function() {$(obj2).show();})
}
if(!o.child){var next = $(obj).children(':nth-child(2)');
}else{var next = o.child;
}
$(next).fadeIn(o.fadeSpeed, function() {
$(next).delay(o.pauseSpeed).fadeOut(o.fadeSpeed, function() {
var next = $(this).next();
if (next.length == 0){
next = $(obj).children(':nth-child(2)');
}
$(obj).rotaterator({child : next, fadeSpeed : o.fadeSpeed, pauseSpeed : o.pauseSpeed});
})
});
});
}
});
})(jQuery);
and call
(function ($) {
$('ul').rotaterator({fadeSpeed:5000, pauseSpeed:1000});
})(jQuery);
Thanks for looking.
UPDATE:
I have added window resize, it seems it's had an affect of how it initially loads and performs thereafter, showing all elements first, please see updated fiddle demo
Your current implementation already adapts to the new window size as soon as the fade-out completes and the next call to rotaterator is made.
If however you want an immediate effect at the resize event, so that the animation restarts taking the new window size into account, then use the jQuery stop method to stop any current animations of an ul child element.
For instance:
$(window).resize(function() {
$('ul *').finish();
$('ul').rotaterator({fadeSpeed:5000, pauseSpeed:1000});
});
So I'm putting something together for work, I've got it working exactly how I want it to, except for one tiny thing. At the bottom of the page, I have 3 circles that work as links to change the slides on my slider, however when I click one it doesn't quite change the css property to change the color of the circle I click on. This might not make sense so I'm going to link my fiddle(http://jsfiddle.net/AMN6N/1/) I think it has something specifically to do with this line of code:
handleNavClick: function(event, el)
{
event.preventDefault();
var position = $(el).attr("href").split("-").pop();
this.el.slider.animate(
{
scrollLeft: position * this.slideWidth
},
this.timing);
this.changeActiveNav(el);
},
changeActiveNav: function(el)
{
this.el.allNavButtons.removeClass("active");
$(el).addClass("active");
}
};
slider.init();
Here is the temporary link for the webpage.
You will need to load just one SimplySliderTest.js file.
The elements are loading after the javascript is being executed so nothing is binding to them.
You have two options:
Load the JS inside SimplySliderTest.js when the page has loaded. i.e.
$(function(){
var slider =
{
el:
{
slider: $("#slider"),
allSlides: $(".slide"),
sliderNav: $(".slider-nav"),
allNavButtons: $(".slider-nav > a")
},
timing: 800,
slideWidth: 300,
init: function()
{
this.bindUIEvents();
},
bindUIEvents: function()
{
this.el.slider.on("scroll", function(event)
{
slider.moveSlidePosition(event);
});
this.el.sliderNav.on("click", "a", function(event)
{
slider.handleNavClick(event, this);
});
},
moveSlidePosition: function(event)
{
this.el.allSlides.css(
{
"background-position": $(event.target).scrollLeft()/6-100+ "px 0"
});
},
handleNavClick: function(event, el)
{
event.preventDefault();
var position = $(el).attr("href").split("-").pop();
this.el.slider.animate(
{
scrollLeft: position * this.slideWidth
},
this.timing);
this.changeActiveNav(el);
},
changeActiveNav: function(el)
{
this.el.allNavButtons.removeClass("active");
$(el).addClass("active");
}
};
slider.init();
});
Move you <script type="text/javascript" src="SimplySliderTest.js"></script> to the bottom of your page so it loads after the elements
I'm using the ShowHide Plugin and I'm trying to get it to fade in instead of toggle/slide into view. Here is what I have:
showHide.js
(function ($) {
$.fn.showHide = function (options) {
//default vars for the plugin
var defaults = {
speed: 1000,
easing: '',
changeText: 0,
showText: 'Show',
hideText: 'Hide'
};
var options = $.extend(defaults, options);
$(this).click(function () {
// optionally add the class .toggleDiv to each div you want to automatically close
$('.toggleDiv').slideUp(options.speed, options.easing);
// this var stores which button you've clicked
var toggleClick = $(this);
// this reads the rel attribute of the button to determine which div id to toggle
var toggleDiv = $(this).attr('rel');
// here we toggle show/hide the correct div at the right speed and using which easing effect
$(toggleDiv).slideToggle(options.speed, options.easing, function() {
// this only fires once the animation is completed
if(options.changeText==1){
$(toggleDiv).is(":visible") ? toggleClick.text(options.hideText) : toggleClick.text(options.showText);
}
});
return false;
});
};
})(jQuery);
$(document).ready(function(){
$('.show_hide').showHide({
speed: 1000, // speed you want the toggle to happen
easing: '', // the animation effect you want. Remove this line if you dont want an effect and if you haven't included jQuery UI
changeText: 1, // if you dont want the button text to change, set this to 0
showText: 'View',// the button text to show when a div is closed
hideText: 'Close' // the button text to show when a div is open
});
});
HTML
<a class="show_hide" href="#" rel="#slidingDiv">View</a></pre>
<div id="slidingDiv" class="toggleDiv" style="display: none;">Fill this space with really interesting content.</div>
<pre>
<a class="show_hide" href="#" rel="#slidingDiv_2">View</a></pre>
<div id="slidingDiv_2" class="toggleDiv" style="display: none;">Fill this space with really interesting content.</div>
<pre>
There is a bug in the line $('.toggleDiv').slideUp(options.speed, options.easing);, here you should not slideup the target div - use $('.toggleDiv').not(toggleDiv).slideUp(options.speed, options.easing);
Try
(function ($) {
$.fn.showHide = function (options) {
//default vars for the plugin
var defaults = {
speed: 1000,
easing: '',
changeText: 0,
showText: 'Show',
hideText: 'Hide'
};
var options = $.extend(defaults, options);
$(this).click(function () {
// this var stores which button you've clicked
var toggleClick = $(this);
// this reads the rel attribute of the button to determine which div id to toggle
var toggleDiv = $(this).attr('rel');
// optionally add the class .toggleDiv to each div you want to automatically close
$('.toggleDiv').not(toggleDiv).slideUp(options.speed, options.easing);
// here we toggle show/hide the correct div at the right speed and using which easing effect
$(toggleDiv).slideToggle(options.speed, options.easing, function () {
// this only fires once the animation is completed
if (options.changeText) {
$(toggleDiv).is(":visible") ? toggleClick.text(options.hideText) : toggleClick.text(options.showText);
}
});
return false;
});
};
})(jQuery);
Demo: Fiddle
I have two similar functions that I would like to combine so that I can use anywhere throughout the site. It's a simple jquery slideUp / slideDown effect that finds the div with the class 'hidden' and on click, it shows and hides
$('.clicker1').click(function(){
// grab the hidden content
var desc = $(this).parent().find('.hidden');
// remove toggle class and slide up
if ($(this).hasClass('toggled')) {
$(this).removeClass('toggled');
$(desc).slideUp(400, 'linear');
}
// add toggle class, slide down, and move the page up
else {
var loc = this;
$(desc).slideDown(400, 'linear', function () {
$.scrollTo($(loc).offset().top - 60, 400);
});
$(this).addClass('toggled');
$('.clicker1').not(this).removeClass('toggled');
$('.hidden').not(desc).slideUp(400, 'linear');
}
});
$('.clicker2').click(function(){
// grab the hidden content
var desc = $(this).parent().find('.hidden2');
// remove toggle class and slide up
if ($(this).hasClass('toggled')) {
$(this).removeClass('toggled');
$(desc).slideUp(400, 'linear');
}
// add toggle class, slide down, and move the page up
else {
var loc = this;
$(desc).slideDown(400, 'linear', function () {
$.scrollTo($(loc).offset().top - 60, 400);
});
$(this).addClass('toggled');
$('.clicker2').not(this).removeClass('toggled');
$('.hidden').not(desc).slideUp(400, 'linear');
}
});
Can I create one function and put in my own 'clickerX' and 'hiddenX' ?
It looks like the handlers only differ by the class's they use as selectors. The easiest approach is to write a function which generates a click handler based on the class names. Try the following
var makeHandler = function(className, hiddenClassName, ) {
return function() {
// grab the hidden content
var desc = $(this).parent().find(hiddenClassName);
// remove toggle class and slide up
if ($(this).hasClass('toggled')) {
$(this).removeClass('toggled');
$(desc).slideUp(400, 'linear');
}
// add toggle class, slide down, and move the page up
else {
var loc = this;
$(desc).slideDown(400, 'linear', function () {
$.scrollTo($(loc).offset().top - 60, 400);
});
$(this).addClass('toggled');
$(className).not(this).removeClass('toggled');
$(hiddenClassName).not(desc).slideUp(400, 'linear');
};
};
$('.clicker1').click(makeHandler('.clicker1', '.hidden'));
$('.clicker2').click(makeHandler('.clicker2', '.hidden2'));
Absolutely. You want to write a plugin. There's tons of tutorials on making a jQuery plugin, but the official docs give a good start.
I'm trying to code a function that let me toggle in and out all thumbnails in a list depending on their classes.
e.g., if I click "print" on my menu bar, I need all thumbs with the "print" class to be hidden. If I click it a second time, the hidden thumbs are showing up.
Here is what I came up with :
window.addEvent('domready', function(){
$$('.menu_button').toggle(
function() {
this.fade(0.5);
var buttonId = this.id;
$('slider_list').getElements('.'+buttonId).each(function(li) {
li.tween('width','0');
});
},
function() {
this.fade(1);
var buttonId = this.id;
$('slider_list').getElements('.'+buttonId).each(function(li) {
li.tween('width','100');
});
}
);
});
//toggle (emulate JQuery's toggle)
(function() {
var toggled = 0;
Element.implement({
toggle: function(fn1, fn2) {
var fns = [fn1, fn2];
return this.addEvent('click', function(){
fns[toggled].apply(this, arguments);
toggled = toggled == 0 ? 1 : 0;
});
}
});
})();
I've found the toggle function here
Now I experience some issues.
First no matter what I do there will always be a thumb left at the end of the list.
Then some clicks on the menu won't do anything. Generally when I click on a button in a different state (hidden/shown) than the previous one, there will always be a null click...
Anybody ?
I implemented it in a way that allows multiple functions, although not at all MooTools like, it will work. The problem with the code you are using is that each element which uses toggle is toggling the same toggled variable
Element.implement({
toggle: function() {
this.store('toggle_options', {
fn: arguments,
cur: 0
});
this.addEvent('click', function(e) {
e.stop();
var opts = this.retrieve('toggle_options');
console.log(opts.fn.length, opts.cur);
opts.fn[opts.cur++].apply(this);
if(opts.cur >= opts.fn.length) opts.cur = 0;
});
}
});
$('button').toggle(
function() {
this.set('text', 'foo 1');
},
function() {
this.set('text', 'bar 2');
}
);
fiddle here: http://jsfiddle.net/94FFj/
Although I would recommend you implemented your code as this:
$$('.menu_button').each(function(button) {
button.store('toggle_active', 0);
button.addEvent('click', function(e) {
e.stop();
var active = this.retrieve('toggle_active');
var opts = [{opacity: 1, width: 0}, {opacity: 0.5, width: 100}];
this.fade(opts[active].opacity);
$$('slider_list .' + this.get('id')).tween('width', opts[active].width);
this.store('toggle_active', active ? 0 : 1);
});
})
