I want to start and stop an animation when click on the same div.
$('div').click(function(){
//if is the first click -->do animation in loop
//if is the second click--->stop animation
});
How do u do it?
I had resolve only the animation start with loop:
var play = 0;
function myAnimateGreen(){
$('green').animate(
{left:'+250px'},
1000,
);
while(play==1) {myAnimateGreen();}
}
$('green').click(function(){
play = 1;
myAnimateGreen();}
});
But I can't resolve the stop!
You can use the :animated selector to detect if the animation is currently happening
$('div').click(function(){
if( !$(".green").is(':animated') ) {
//Do animation
} else {
//Stop animation
}
});
function animateGreen(el) {
var delay = 500,
time = 1000,
distance = 150;
el.animate({left:'+='+distance+'px'}, time, "linear");
el.data("anim_green", setTimeout(animateGreen, time+delay, el));
}
$('green').click(function() {
var self = $(this);
if (self.data("anim_green")) {
clearTimeout(self.data("anim_green"));
self.data("anim_green", false);
return;
}
animateGreen(self);
});
Should do it, just paste! Proof: http://jsbin.com/ajagij/3/edit

Here is a code that should open and close my site's menu. The menu is divided to divs and each one is timed to enter the screen after the other.
<script type="text/javascript">
var s=0;
function menuOpen() {
if (s==0){
document.getElementById("menu_icon").src = "x.png";
document.getElementById("nav_menu").style.zIndex = "3";
$('.box-wrapper').each(function(index, element) {
setTimeout(function(){
element.classList.remove('loading');
}, index * 100);
});
s++;
} else {
document.getElementById("menu_icon").src = "menu_icon.png";
$('.box-wrapper').each(function(index, element) {
setTimeout(function(){
element.classList.add('loading');
}, index * 100);
});
s=0;
// how to make this part run after the menu has finished folding?
setTimeout(function(){
document.getElementById("nav_menu").style.zIndex = "1";
}, 1500);
}
}
</script>
The content of the page is at z-index 2. The menu when folded is at 1 and when open at 3.
Is there a way to run the command moving the menu to z-index 1 after the menu has finished folding completely?
Currently what I did was to time the animation (1600ms) and use setTimeout. But this timing will change if I'll add more lines to my menu or if someone is clicking rapidly on the menu icon.
I'm rather new to JS and Jquery so go easy on me (:
Thanks of your help.
Below you can find the code and link to jsfiddle. Unfortunetly jsfiddle blocks the animate method for unknown reason so I don't debug, but even if it code will not work :))) I hope you will cathch the idea. And also some explanation.
Firstly our items are hidden. There are two functions displayMenu and hideMenu, they are similar, but display - run animations from the top invisible, and hide - start hide items from the bottom visible. To prevent mess I use two flags and two classes, first openFlag it is say what animations should be played now. Our hide and display functions are recursive and after they end current animation(hide or show) they check openFlag, and play next hide/show or start another chain of hide/show functions. It is the most difficult to understand part) But important that with it you can click as many times as you want and all would be fine and would be never broken by clicks.
Two classes we use as animation-chain can change behaviour and we need the way to choose items that alredy visible or hidden, so this why after each animation we set only one of this classes and remove another.
Now there is one problem if all animation are ended when we click button we should start new chain of animations, but if chain has been already started we need just to switch openFlag, and when current animation stops, it will change the behaviour. So this is the reason for btnFlag it is 1 if no active chain-animations at this moment.
After the last execution of element of animation-chain it will call callback arg, that you should pass, also at this moment will set btnFlag to 0, that means that animation-chain stopped. The openFlag as you remember changed at moment og click.
function end() {
console.log("here you can set zIndex");
}
var openFlag = 0; //become 1 after we start open elems
var btnFlag = 1;
$(document).ready(function() {
$('.toggleMenu').click(function() {
if (!$('.menuBlocks').hasClass('visible')) {
if (openFlag == 0) {
openFlag = 1;
if (btnFlag) {
var items = $('.invisibleItem');
var amount = items.length;
displayMenu(0, amount, items, end);
}
}
} else {
openFlag = 0;
if (btnFlag) {
var items = $('.visibleItem');
var amount = items.length;
hideMenu(amount - 1, items, end);
}
}
});
});
function displayMenu(i, amount, items, callback) {
if (i < amount && openFlag) {
items[i].animate({
"width": "100px"
}, 1000, function() {
items[i].removeClass('invisibleItem');
items[i].addClass('visibleItem');
displayMenu(i + 1, amount, items);
});
} else if (!openFlag) {
var items = $('.visibleItem');
var amount = items.length;
hideMenu(amount - 1, items, makeToggleVisible);
} else {
btnFlag = 1; //all aniimations ended
callback();
}
}
function hideMenu(i, items, callback) {
if (i < 0 && openFlag) {
items[i].animate({
"width": "0px"
}, 1000, function() {
items[i].removeClass('visibleItem');
items[i].addClass('invisibleItem');
hideMenu(i - 1, amount, items);
});
} else if (!openFlag) {
var items = $('.invisibleItem');
var amount = items.length;
displayMenu(0, amount, items, makeToggleVisible);
} else {
btnFlag = 1; //all animations are ended
callback();
}
}

Ok fixed it.
I moved everything to jquery. Used animate and promise.
This is what came out at the end. It is a side menu that will open it's li elements one-by-one.
var s=0;
var navMenu = document.getElementById("nav_menu");
var navBtn = document.getElementById("btn");
$(document).ready(function(){
$("button").click(function(){
if (s==0) {
navMenu.style.zIndex = "4";
navBtn.classList.add('close');
$('ul').each(function() {
$(this).children().each(function(i) {
$(this).delay(i * 100).animate({left:0});
});
});
$( "li" ).promise().done(function() {
navMenu.style.zIndex = "4";
});
s++;
}
else {
navBtn.classList.remove('close');
$('ul').each(function() {
$(this).children().each(function(i) {
$(this).delay(i * 100).animate({left:"100%"});
});
});
s=0;
$( "li" ).promise().done(function() {
navMenu.style.zIndex = "1";
});
}
});
});
and with CSS transitions.
var s=0;
function menuOpen() {
if (s==0){
document.getElementById("menu_icon").src = "x.png";
document.getElementById("nav_menu").style.zIndex = "3";
$('.box-wrapper').each(function(index, element) {
setTimeout(function(){
element.classList.remove('loading');
}, index * 100);
});
s++;
$("#last").bind("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){
document.getElementById("nav_menu").style.zIndex = "3";
});
} else {
document.getElementById("menu_icon").src = "menu_icon.png";
$('.box-wrapper').each(function(index, element) {
setTimeout(function(){
element.classList.add('loading');
}, index * 100);
});
s=0;
$("#last").bind("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){
document.getElementById("nav_menu").style.zIndex = "1";
$("#nav_menu").scrollTop(0);
});
}
}
I am facing one problem in JS, please help me to resolve this.. I have two methods they are simultaneously executing one after other.. I have to stop them after second click on image.
Below is my JS code
I am calling fadeIn(img1, img2, img3) after first click on image then some animation will be goes on, once I click second time the whole animation(method execution) should be stopped.
var t1 = 0;
var t2 = 0;
function fadeIn(img1, img2, img3) {
$(imgIdForClick_1).addClass('animated pulse');
$('#cashBar1').addClass('animated pulse');
$('#cashBarDec1').addClass('animated pulse');
var t1 = setTimeout(function() {
fadeOut(img1, img2, img3);
if (clickCount_1 >= 2) {
alert("clicked 1");
return false;
}
}, 500);
//t1 = setTimeout(fadeOut, 500);
};
function fadeOut(img11, img22, img33) {
$(imgIdForClick_1).removeClass('animated pulse');
$('#cashBar1').removeClass('animated pulse');
$('#cashBarDec1').removeClass('animated pulse');
var t2 = setTimeout(function() {
fadeIn(img11, img22, img33);
if (clickCount_1 >= 2) {
alert("clicked 2");
return false;
}
}, 500);
//t2 = setTimeout(fadeIn, 500);
};
By below code I am calling this snippet in first click
imgId1 = $('#img1');
imgId2 = $('#cashBar1');
imgId3 = $('#cashBarDec1');
fadeIn(imgId1, imgId2, imgId3);
After second click
clickCount_1 varibale will be 2
clearTimeout(t1);
clearTimeout(t2);
See the DEMO. Click on the image to stop animation.
I have added a flag that would be checked upon the call of the function, and if the value is true then and then only the functions would be called. The flag would be set to false when clicked on image, so the function would be called no longer.
code:
var animate = true;
function fadeIn() {
$('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
if(animate == true)
{
setTimeout(fadeOut,1000);
}
};
function fadeOut() {
$('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
if(animate == true)
{
setTimeout(fadeIn,1000);
}
};
fadeIn();
$('#image').click(function(){
animate = false;
alert('now the animation will stop');
});
I created this little function that loops through images when you go mouse over:
function THUMB_ROLL(NEXT)
{
LENGTH = ALL_IMAGES.length;
if(!LENGTH) { return false; }
if(!NEXT || NEXT === LENGTH) { NEXT = 0 }
$('#IMAGE_THUMB').css('background-image','url(/<?php echo $ITEM_CODE;?>/'+ALL_IMAGES[NEXT]+')');
setTimeout(function()
{
THUMB_ROLL(NEXT+2)
},800);
}
</script>
I have, onmouseover="THUMB_ROLL();"
But, I cannot seem to find a solution to stop the loop once onmouseout. Any help appreciated!
EDIT
<script>
var timer;
function THUMB_ROLL(NEXT)
{
LENGTH = ALL_IMAGES.length;
if(!LENGTH) { return false; }
if(!NEXT || NEXT === LENGTH) { NEXT = 0 }
$('#IMAGE_THUMB').css('background-image','url(/<?php echo $ITEM_CODE;?>/'+ALL_IMAGES[NEXT]+')');
timer = setTimeout(function()
{
THUMB_ROLL(NEXT+1)
},800);
}
$(document).on('mouseover','#IMAGE_THUMB',function()
{
THUMB_ROLL();
});
$(document).on('mouseout','#IMAGE_THUMB',function()
{
clearTimeout(timer);
});
</script>
Assign your timeout to a variable which store the timerID.
Then have the moueout clear the timeout, which should stop the flow.
var timer;
// mouseover event..
timer = setTimeout(function() {
THUMB_ROLL(NEXT+2)
},800);
// mouseout event
clearTimeout(timer);
Also it is a better idea to separate your concerns and attach the events inside the script tags instead of attaching them inline.
Based on this script I found on Stack Overflow, I tried adapting it to fade out an editor panel on a HTML page. Fading out works fine, but I'd like limit the fade-out from being triggered.
What I hope to accomplish is to prevent the fade-out whenever the mouse is over the editor panel (and child controls) or when there's keyboard activity in one of the input children.
var i = null;
// this part is working
$("#my-canvas").mousemove(function() {
clearTimeout(i);
$("#panel,#btn-panel-toggle,#fps").fadeIn(200);
var i = setTimeout('$("#panel,#btn-panel-toggle,#fps").fadeOut(800);', 3000);
})
// this part is not working
$("#panel").mouseover(function() {
clearTimeout(i);
})
For a live example, please check out this jsFiddle.
Two independent variables are needed here to indicate, whether the input#sc-url is focused and div#panel is hovered by mouse or not. Then you can handle the timer with these functions:
$(function () {
var t = null; //timer
var is_url_focused = false, is_panel_hovered = false;
var panel = $('#panel');
function hide_panel(){
if (t) {
clearTimeout(t);
}
t = setTimeout(function(){
if (is_url_focused || is_panel_hovered) {
return;
}
panel.stop().animate({
opacity:0
},800, function(){
panel.hide(); // == diplay:none
});
},2000);
}
function show_panel(){
panel.show().stop().animate({
opacity:1
},800);
}
$('#my-canvas').mouseenter(function(){
show_panel();
}).mouseleave(function(){
hide_panel();
});
$('#panel').hover(function(){
is_panel_hovered = true;
show_panel();
}, function(){
is_panel_hovered = false;
hide_panel();
});
$('#sc-url').focus(function(){
is_url_focused = true;
show_panel();
}).blur(function(){
is_url_focused = false;
hide_panel();
});
$('#btn-panel-toggle').click(function(){
if (panel.is(':hidden')) {
panel.css('opacity',1).show();
} else {
panel.css('opacity',0).hide();
}
});
});

I have a simple function that animates a bunch of images by crossfading them. A simple banner rotation. I set up the function so that calling animateSlideshow("play") it should set the timeout and start animating and by calling animateSlideshow("stop") it should stop.
When I call stop, however, the animation happens one more time. What is the cause for this one extra animation and how can I deal with it?
this calls the function on the bottom
function prevSlide(e){
if(curHashIndex !== 0){
$(prevBtn).off();
// Stop the current slideshow
animateSlideshow("stop");
// Reset the current slideshow
$("li.active .rightSlide > li").fadeOut(600).eq(0).fadeIn(600).addClass("actvImg");
$(".rightSlides").animate({
"left" : '+=345'
}, 600, function(){
$(prevBtn).on('click', prevSlide);
});
$(".leftSlides").animate({
"left" : '+=417'
}, 600);
// Activate the new slide
$(".rightSlides li.active").removeClass("active").prev().addClass("active");
activeSlide = $(".rightSlides li.active");
total = $(".rightSlides li.active .rightSlide > li").length;
// Start slideshow on the new slide
var delay = setTimeout(animateSlideshow("play"), 10000);
updateHash();
}
}
function animateSlideshow(action){
if(action === "play"){
$(activeSlide).data('animateSlideshow',
setTimeout(function(){
if( $(actvImg).index() === total - 1 ){
$(actvImg).fadeOut(animationSpeed).removeClass("actvImg").siblings().eq(0).fadeIn(animationSpeed).addClass("actvImg");
}else{
$(actvImg).fadeOut(animationSpeed).removeClass("actvImg").next().fadeIn(animationSpeed).addClass("actvImg");
}
actvImg = $(".rightSlides li.active .rightSlide > li.actvImg");
actvImgIndx = $(actvImg).index();
updateBreadcrumbs();
animateSlideshow("play")
}, animationTimeout)
);
}else{
clearTimeout($(activeSlide).data('animateSlideshow'));
};
};
You should use setInterval() / clearInterval() rather than recalling the function using setTimeout().
function animateSlideshow(action){
if(action === "play"){
$(activeSlide).data('animateSlideshow',
setInterval(function(){
if( $(actvImg).index() === total - 1 ){
$(actvImg).fadeOut(animationSpeed).removeClass("actvImg").siblings().eq(0).fadeIn(animationSpeed).addClass("actvImg");
}else{
$(actvImg).fadeOut(animationSpeed).removeClass("actvImg").next().fadeIn(animationSpeed).addClass("actvImg");
}
actvImg = $(".rightSlides li.active .rightSlide > li.actvImg");
actvImgIndx = $(actvImg).index();
updateBreadcrumbs();
}, animationTimeout);
);
}else{
clearInterval($(activeSlide).data('animateSlideshow'));
};
};
I am not sure why it is failing for you, but I tried a similar demo and it worked for me..
DEMO here
Additionally, I used .stop() to stop the current animation. You can use it if you want to stop the current animation on that object.
