Applying a transition in between two states with Javascript behaving erratically - javascript

I'm struggling to understand why the transitions don't behave as expected. It's supposed to apply the "from", then add the "transition" to the "el", then it's supposed to run "to" and finally onTransitionEnd it's supposed to run "callback" (prepended to which is a bit of code which clears the transition properties).
In Webkit browsers, it transitions slideDown correctly, but slideUp is instant. Reverse is true in Firefox.
Erg?
JSFiddle: http://jsfiddle.net/enhTd/
var $ = function(query) {
var a = [],
n = document.querySelectorAll(query),
l = n.length;
for( var i = 0; i<l; i++){
a.push(n[i]);
}
if(l>1) {return a;} else {return a[0];}
},
$id = function(query) { return document.getElementById(query);},
getSupportedPropertyName = function(properties) {
for (var i = 0; i < properties.length; i++) {
if (typeof document.body.style[properties[i]] != "undefined") {
return properties[i];
}
}
return null;
},
vendorTransitions = ["transition", "msTransition", "webkitTransition", "MozTransition", "OTransition"],
prefixedTransitionProperty = getSupportedPropertyName(vendorTransitions),
transition = function(opts){
opts.from && opts.from();
if(prefixedTransitionProperty){
var c = opts.callback || function() {},
el = opts.el,
cb = function(event){
var ev = event, callback = c;
ev.target.removeEventListener(prefixedTransitionProperty+"End", cb);
ev.target.style[prefixedTransitionProperty] = "none";
if(callback) {
callback(ev);
}
};
el.style[prefixedTransitionProperty] = opts.transition || "";
el.addEventListener(prefixedTransitionProperty+"End", cb);
}
opts.to && opts.to();
},
slideDown = function(el, t){
var style = el.style,
h, oh = el.offsetHeight,
t = t || 1000;
//Grab real height
style.height = "";
h = el.offsetHeight;
transition({
"el": el,
transition: "height "+t+"ms ease",
from: function() {
style.height = oh+"px";
},
to: function(){
style.overflow = "hidden";
style.height = h+"px";
},
callback: function(event){
event.target.style.height = "";
}
});
},
slideUp = function(el, t){
var style = el.style,
h = el.offsetHeight,
t = t || 1000;
transition({
"el": el,
transition: "height "+t+"ms ease",
from: function() {
style.height = h+"px";
},
to: function(){
style.overflow = "hidden";
style.height = "0";
}
});
},
slideToggle = function(el, t){
var t = t || 1000;
if(el.style.height=="0px"){
slideDown(el, t);
} else {
slideUp(el, t);
}
};
slideUp($id("intro"));
$("a[href='#intro']").forEach(function(el){
el.addEventListener("click", function(ev) {
ev.preventDefault();
if(ev.target.classList.contains("hide")){
slideUp($(ev.target.hash));
} else {
slideDown($(ev.target.hash));
}
});
});
$("li h3").forEach(function(el){
el.addEventListener("click", function(ev) {
ev.preventDefault();
slideToggle(ev.target.parentNode);
});
});

In some browsers, you cannot just set the initial state, set the final state and expect a CSS transition to work.
Instead, the initial state must be set and then it must be rendered before you can set the final state and expect the transition to run. The simplest way to cause it to be rendered is to return back to the event loop and then do any further processing (like setting the final state) after a setTimeout() call.

try this: http://jsfiddle.net/enhTd/1/ (tested in chrome and ff)
first: do what jfriend00 talked about:
in your transition function:
transition = function (opts) {
..
setTimeout(function() {
opts.to && opts.to();
}, 1)
}
second: the callback wasn't necessary in your slideDown() method:
slideDown = function (el, t) {
..
take this out:
/*callback: function (event) {
event.target.style.height = "";
}*/
});
from a design point of view.. the callback function wasn't adding any value.. you should just continue from where you left off when it comes to transitions.
third: disable slide down when the slide is already down.. but I'll leave that to you.

Convert script for working with multiple instances

Lets see this script, that it's a simple carrousel
$script = {
init: function(){
this.heros(3000);
},
heros: function (time) {
var t;
var $hero = $('.hero');
var $images = $('.hero > div');
$hero.data('current', 0);
var $bullets = $('<div>').addClass('bullets');
for ( var i = 0; i<$images.length; i++ ) {
var $item = $('<span>');
$item.on('click', function () {
clearTimeout(t);
play( $(this).index() );
});
if(i==0) { $item.addClass('active') }
$bullets.append( $item );
}
var play = function (current) {
if(current==undefined) {
current = $hero.data('current');
}
var nextMargin;
if ( (current+1) == $images.length ) {
nextMargin = 0 ;
$hero.data('current',0);
} else {
nextMargin = (current + 1 )*100;
$hero.data('current', (current + 1));
}
$images.eq(0).css('marginLeft', -nextMargin + '%');
$bullets.find('span').eq($hero.data('current')).addClass('active').siblings().removeClass('active');
clearTimeout(t);
t = setTimeout(play, time);
}
$hero.append($bullets);
t = setTimeout(play, time);
},
}
The thing is that it works great, but only if there's just one .hero element.. if there are multiple the bullets mix up and it doesn't respect the .length
I know that option one should be rewrite it again, but Does anyone of you sees a quick fix that would make it reusable?
A single fiddle: https://jsfiddle.net/6z8n5pnq/
A multiple fiddle: https://jsfiddle.net/6z8n5pnq/1/
-EDIT-
I tried:
Defining a previous function, that is called on init
preheros: function(time) {
var self = this;
$('.heros').each(function(){
self.heros($(this), time);
});
},
And editing The begining of heros:
heros: function ($hero, time) {
var t;
/*var $hero = $('.hero');*/
var $images = $hero.find('>div');
but no success...
any idea?
-EDIT-
GOD, it's $('.hero').each not $('.heros').each it was working!
The easiest way to do this is to isolate context for each .hero component by using $(selector).each function. Slightly corrected your fiddle https://jsfiddle.net/6z8n5pnq/2/
function apply($hero, time){
var t;
var $images = $hero.children('div');
//all your logic here...
}
$script = {
init: function () {
this.heros(3000);
},
heros: function (time) {
$('.hero').each(function(){
apply($(this), time);
});
},
}

mootools | Hide and show animation

I have a mootools code:
(function() {
var index = 0;
Element.implement({
toggle: function() {
var args = Array.slice(arguments, 0);
count = args.length - 1;
return this.addEvent("click", function() {
args[index].apply(this, arguments);
index = (count > index) ? index + 1 : 0;
});
},
resetToggle: function() {
index = 0;
}
});
})();
document.getElement(".toggle").toggle(
function() {
document.id("menu").setStyle("display", "block");
}, function() {
document.id("menu").setStyle("display", "none");
}
);
});
How to hide/show div.menu container with animation?
Thanks!
haha this looks like my old toggle code :) do:
document.id('menu').setStyles({
display: 'block',
opacity: 0
}).fade(1);
and the opposite.
update to:
(function(){
var Element = this.Element,
Elements = this.Elements;
[Element, Elements].invoke('implement', {
toggle: function(){
var args = Array.prototype.slice.call(arguments),
count = args.length-1,
// start at 0
index = 0;
return this.addEvent('click', function(){
var fn = args[index];
typeof fn === 'function' && fn.apply(this, arguments);
// loop args.
index = count > index ? index+1 : 0;
});
}
});
}());
If you want to make a animation you could use reveal() / dissolve() available in MooTools-More
document.getElement(".toggle").toggle(function () {
document.id("menu").reveal();
}, function () {
document.id("menu").dissolve();
});
Note you had a pair }); too much in your code (last line)
Example
But if you would use more, there is already a .toggle() method you can use, that would give you just show/hide like this.

Detect if clicking outside of element (Must support clicking in overlay elements)

Current best solution i have found:
ko.bindingHandlers.clickedIn = (function () {
function getBounds(element) {
var pos = element.offset();
return {
x: pos.left,
x2: pos.left + element.outerWidth(),
y: pos.top,
y2: pos.top + element.outerHeight()
};
}
function hitTest(o, l) {
function getOffset(o) {
for (var r = { l: o.offsetLeft, t: o.offsetTop, r: o.offsetWidth, b: o.offsetHeight };
o = o.offsetParent; r.l += o.offsetLeft, r.t += o.offsetTop);
return r.r += r.l, r.b += r.t, r;
}
for (var b, s, r = [], a = getOffset(o), j = isNaN(l.length), i = (j ? l = [l] : l).length; i;
b = getOffset(l[--i]), (a.l == b.l || (a.l > b.l ? a.l <= b.r : b.l <= a.r))
&& (a.t == b.t || (a.t > b.t ? a.t <= b.b : b.t <= a.b)) && (r[r.length] = l[i]));
return j ? !!r.length : r;
}
return {
init: function (element, valueAccessor) {
var target = valueAccessor();
$(document).click(function (e) {
if (element._clickedInElementShowing === false && target()) {
var $element = $(element);
var bounds = getBounds($element);
var possibleOverlays = $("[style*=z-index],[style*=absolute]").not(":hidden");
$.each(possibleOverlays, function () {
if (hitTest(element, this)) {
var b = getBounds($(this));
bounds.x = Math.min(bounds.x, b.x);
bounds.x2 = Math.max(bounds.x2, b.x2);
bounds.y = Math.min(bounds.y, b.y);
bounds.y2 = Math.max(bounds.y2, b.y2);
}
});
if (e.clientX < bounds.x || e.clientX > bounds.x2 ||
e.clientY < bounds.y || e.clientY > bounds.y2) {
target(false);
}
}
element._clickedInElementShowing = false;
});
$(element).click(function (e) {
e.stopPropagation();
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
})();
It works by first query for all elements with either z-index or absolute position that are visible. It then hit tests those elemnts against the elemnet I want to hide if click outside. If its a hit I calculate a new bound retacle which takes into acount the overlay bounds.
Its not rock solid, but works. Please feel free to comment if you see problems with above approuch
Old question
I'm using Knockout but this applies to DOM/Javascript in general
Im trying to find a reliable way if detecting of you click outside of a element. My code looks like this
ko.bindingHandlers.clickedIn = {
init: function (element, valueAccessor) {
var target = valueAccessor();
var clickedIn = false;
ko.utils.registerEventHandler(document, "click", function (e) {
if (!clickedIn && element._clickedInElementShowing === false) {
target(e.target == element);
}
clickedIn = false;
element._clickedInElementShowing = false;
});
ko.utils.registerEventHandler(element, "click", function (e) {
clickedIn = true;
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
It works by both listening to click on target element and document. If you click on document but not target element you click outside of it. This works, but, not for overlay items like datepickers etc. This is because these are not inside the target element but in the body. Can I fix this? Are there better way of determine if clicking outside of element?
edit: This kind of works, but only if the overlay is smaller than the element i want to monitor
ko.bindingHandlers.clickedIn = {
init: function (element, valueAccessor) {
var target = valueAccessor();
$(document).click(function (e) {
if (element._clickedInElementShowing === false) {
var $element = $(element);
var pos = $element.offset();
if (e.clientX < pos.left || e.clientX > (pos.left + $element.width()) ||
e.clientY < pos.top || e.clientY > (pos.top + $element.height())) {
target(false);
}
}
element._clickedInElementShowing = false;
});
$(element).click(function (e) {
e.stopPropagation();
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
I would like a more rock solid approuch
This is how I usually solve it:
http://jsfiddle.net/jonigiuro/KLxnV/
$('.container').on('click', function(e) {
alert('hide the child');
});
$('.child').on('click', function(e) {
alert('do nothing');
e.stopPropagation(); //THIS IS THE IMPORTANT PART
});
I don't know how your overlay items are generated, but you could always check if the click target is a child of the element you want to constrain your clicks to.

how to clear all javascript Timeouts?

i have a loop function that in first 5 seconds it runs social1() and in second 5 seconds it runs social2() then loop ...
i have 2 hover functions too
i need clear all active timeouts because when i hover on images (.social1 & .social2), i can see that multiple timeouts are running
how to fix this?
function social1() {
$('.social1').fadeTo(500, 1);
$('.social2').fadeTo(500, 0.5);
timeout = setTimeout(function() {
social2();
}, 5000);
}
function social2() {
$('.social1').fadeTo(500, 0.5);
$('.social2').fadeTo(500, 1);
timeout = setTimeout(function() {
social1();
}, 5000);
}
$(document).ready(function ()
{
social1();
$('.social1').hover(
function () {
window.clearTimeout(timeout);
social1();
},
function () {
timeout = setTimeout(function() {
social2();
}, 5000);
}
);
$('.social2').hover(
function () {
window.clearTimeout(timeout);
social2();
},
function () {
timeout = setTimeout(function() {
social1();
}, 5000);
}
);
__EDIT__
To manage a collection of timeouts (and intervals), you could use following snippet.
This will allow to clear any timeouts or intervals set anywhere in code, although, you have to set this snippet before setting any timeout or interval. Basically, before processing any javascript code or external script which uses timeout/interval.
JS:
;(function () {
window.timeouts = {},
window.intervals = {},
window.osetTimeout = window.setTimeout,
window.osetInterval = window.setInterval,
window.oclearTimeout = window.clearTimeout,
window.oclearInterval = window.clearInterval,
window.setTimeout = function () {
var args = _parseArgs('timeouts', arguments),
timeout = window.osetTimeout.apply(this, args.args);
window.timeouts[args.ns].push(timeout);
return timeout;
},
window.setInterval = function () {
var args = _parseArgs('intervals', arguments),
interval = window.osetInterval.apply(this, args.args);
window.intervals[args.ns].push(interval);
return interval;
},
window.clearTimeout = function () {
_removeTimer('timeouts', arguments);
},
window.clearInterval = function () {
_removeTimer('intervals', arguments);
},
window.clearAllTimeout = function () {
_clearAllTimer('timeouts', arguments[0]);
},
window.clearAllInterval = function () {
_clearAllTimer('intervals', arguments[0]);
};
function _parseArgs(type, args) {
var ns = typeof args[0] === "function" ? "no_ns" : args[0];
if (ns !== "no_ns")[].splice.call(args, 0, 1);
if (!window[type][ns]) window[type][ns] = [];
return {
ns: ns,
args: args
};
}
function _removeTimer(type, args) {
var fnToCall = type === "timeouts" ? "oclearTimeout" : "oclearInterval",
timerId = args[0];
window[fnToCall].apply(this, args);
for (var k in window[type]) {
for (var i = 0, z = window[type][k].length; i < z; i++) {
if (window[type][k][i] === timerId) {
window[type][k].splice(i, 1);
if (!window[type][k].length) delete window[type][k];
return;
}
}
}
}
function _clearAllTimer(type, ns) {
var timersToClear = ns ? window[type][ns] : (function () {
var timers = [];
for (var k in window[type]) {
timers = timers.concat(window[type][k]);
}
return timers;
}());
for (var i = 0, z = timersToClear.length; i < z; i++) {
_removeTimer(type, [timersToClear[i]]);
}
}
}());
How to use it:
Set timeout(s)/interval(s) as usual:
var test1 = setTimeout(function(){/**/, 1000);
var test2 = setTimeout(function(){/**/, 1000);
Then you could use to clear both:
clearAllTimeout(); // clearAllInterval(); for intervals
This will clear both timeouts (test1 & test2)
You can use some namespaces to clear only specific timers, e.g:
// first (optional) parameter for setTimeout/setInterval is namespace
var test1 = setTimeout('myNamespace', function(){/**/, 1000); // 'myNamespace' is current namespace used for test1 timeout
var test2 = setTimeout(function(){/**/, 1000); // no namespace used for test2 timeout
Again, clearAllTimeout(); will clear both timeouts. To clear only namespaced one, you can use:
clearAllTimeout('myNamespace'); // clearAllInterval('myNamespace'); for namespaced intervals
This will clear only test1 timeout
You could for some reason wish to delete non namespaced timeouts only. You could then use:
clearAllTimeout('no_ns'); // clearAllInterval('no_ns'); for non namespaced intervals only
This will clear only test2 timeout in this example
See jsFiddle DEMO
__END of EDIT__
Old post specific to opening question here:
You could try that:
var timeouts = [];
timeouts.push(setTimeout(function() {
social2();
}, 5000));
timeouts.push(setTimeout(function() {
social1();
}, 5000));
//etc...
function clearAllTimeouts(){
for(var i = 0, z = timeouts.length; i < z; i++)
clearTimeout(timeouts[i]);
timeouts = [];
}
UPDATED following David Thomas comment
var timeouts = {'social' : [], 'antisocial' : []};
//a social timeout
timeouts.social.push(setTimeout(function() {
social1();
}, 5000));
//an anti-social timeout
timeouts.antisocial.push(setTimeout(function() {
antisocial1();
}, 5000));
function clearTimeouts(namespace){
for(var i = 0, z = timeouts[namespace].length; i < z; i++)
clearTimeout(timeouts[namespace][i]);
timeouts[namespace] = [];
}
//usage e.g
clearTimeouts("social");
//Incase if you are looking for full fledged code
var dict = {};
function checkForIntervals(id){
var index = index;
var result = findOrAddProperty(id);
if(result.length != 0){
clearTimeoutsFor(id);
}
dict[id].push(setTimeout(function(){alertFunc(id,index);}, 60000));
};
// to clear specific area timeout
function clearTimeoutsFor(namespace){
for(var i = 0, z = dict[namespace].length; i < z; i++)
clearTimeout(dict[namespace][i]);
dict[namespace] = [];
}
to clear all timeouts
function clearAllTimeOuts(){

Javascript file "FASW transitions" duplicating my header info. How to fix

Ok! I'm working on a wordpress site, and everything this javascript add on is supposed to do, it does...But, when I inspect element via safari develop, I notice that it's loading all of my headers scripts,meta,styles etc. into the body as well as the head. I can't figure out why. Here's what the script looks like:
function ft(params) {
var ol= document.addEventListener?"DOMContentLoaded":"load"; //on load event
var navB = params.navB || "reverse slide"; //backbrowser button effect, default empty
var but = params.but || false; //Allow transitions on input type button
var cBa = params.cBa || function() {};
function aDL(url, t, o) { //Ajax Div Load
if (window.XMLHttpRequest) {
r = new XMLHttpRequest();
} else if (window.ActiveXObject) {
r = new ActiveXObject("Microsoft.XMLHTTP");
}
if (r != undefined) {
r.onreadystatechange = function() {Ol(r, t, o);};
r.open("GET", url, true);
r.send("");
}
}
function Ol(r, t, o) { //On load div
if (r.readyState == 4) {
if (r.status == 200 || r.status == 0) {
t.innerHTML = r.responseText;
o();
} else {
t.innerHTML="Error:\n"+ r.status + "\n" +r.statusText;
}
}
}
function DE() //Div Effect
{
var dochtml = document.body.innerHTML;
document.body.innerHTML = "";
var d1 = document.createElement("div");
d1.id = "d1";
d1.style.zIndex = 2;
d1.style.position = "absolute";
d1.style.width = "100%";
d1.style.height = "100%";
d1.style.left = "0px";
d1.style.top = "0px";
document.body.appendChild(d1);
d1.innerHTML = dochtml;
var d2 = document.createElement("div");
d2.id = "d2";
d2.style.zIndex = 1;
d2.style.position = "absolute";
d2.style.width = "100%";
d2.style.height = "100%";
d2.style.left = "0px";
d2.style.top = "0px";
document.body.appendChild(d2);
return {d1: d1, d2: d2 };
}
function timeOuts(e, d1,d2)
{
setTimeout(function() { d1.className = e + " out"; }, 1);
setTimeout(function() { d2.className = e + " in"; }, 1);
setTimeout(function() {
document.body.innerHTML = d2.innerHTML;
cBa();
}, 706);
}
function slideTo(href, effect, pushstate)
{
var d = DE();
var d1 = d.d1;
var d2 = d.d2;
aDL(href, d2,
function() {
if (pushstate && window.history.pushState) window.history.pushState("", "", href);
timeOuts(effect,d1,d2);
}
);
}
function dC(e){ //Detect click event
var o;
var o=e.srcElement || e.target;
var tn = o.tagName.toLowerCase();
if (!but || tn!="input" || o.getAttribute("type")!="button") //if it is not a button
{
//try to find an anchor parent
while (tn!=="a" && tn!=="body")
{
o = o.parentNode;
tn = o.tagName.toLowerCase();
}
if (tn==="body") return;
}
var t = o.getAttribute("data-ftrans");
if (t)
{
e.preventDefault();
var hr = o.getAttribute("href") || o.getAttribute("data-href");
if (hr) slideTo(hr, t, true);
}
}
function aE(ev, el, f) { //Add event

}
}
aE("click", window, dC);
aE(ol, document, //On load
function(ev)
{
aE("popstate", window, function(e) { //function to reload when back button is clicked
slideTo(location.pathname, navB, false);
});
}
);
}
here is the link to the site: http://www.fasw.ws/faswwp/non-jquery-page-transitions-lightweight/
I assume that thats not supposed to happen. So im trying to figure out how to keep it clean, and keep the head files loaded in the head, and only load the page content. I cannot figure this one out, some help from the pros is needed :)
FASW comes with two functions that serves as "hooks" both before and after initializing the component. you can do it like this:
(function inittrans()
{
initComponents();
var params = { /*put your options here*/ };
new ft(params);
})();
function onTransitionFinished()
{
initComponents();
}
function initComponents() {
// here is where you put your "other" javascript codes
}
Notice how your javascript codes are executed after loading your initial page and once again after the transition happened. Anyway, this is how I got the work around on it 'coz javascript codes just won't work as they are loaded by FASW via Ajax on-the-fly.
