Issue with .mouseleave() and .mouseenter() - javascript

I use .mouseenter() and .mouseleave() to make an animation to my button.The problem is that when I move my cursor across the button multiple times it keeps repeating the animation .For .mouseenter() I want it to complete the animation once the cursor keeps hovering over it till the animation time is complete and if it leaves the button before the animation is complete the animation should stop.For .mouseleave() the animation should stop if the cursor hovers over it before the animation is complete.
$(document).ready(function(){
$('#button').mouseenter(function(){
$(this).animate({backgroundColor:'#ffce00',width:'+=1em'},100);
});
$('#button').mouseleave(function(){
$(this).animate({backgroundColor:'#1e7989',width:'-=1em'},100);
});
});
#button{
width:100px;
height:50px;
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="//cdn.jsdelivr.net/jquery.color-animation/1/mainfile"></script>
<div id="button"></div>

You can use flags for entering and leaving. Then check the appropriate flag, and finish the current animation when an enter/leave event occurs, something like this:
$(document).ready(function () {
var isEntering = false, // Create flags
isLeaving = false;
$('#button').mouseenter(function () {
isEntering = true; // Set enter flag
if (isLeaving) { // Check, if leaving is on process
$(this).finish(); // If leaving, finish it
isLeaving = false; // Reset leaving flag
}
$(this).animate({
backgroundColor: '#ffce00',
width: '+=1em'
}, 100);
});
$('#button').mouseleave(function () {
isLeaving = true; // Set leave flag
if (isEntering) { // Check if entering is on process
$(this).finish(); // If it is, finish it
isEntering = false; // Reset enter flag
}
$(this).animate({
backgroundColor: '#1e7989',
width: '-=1em'
}, 100);
});
});
A live demo at jsFiddle.

Try adding .stop(), it will stop the animations from queueing.
$(document).ready(function(){
$('#button').mouseenter(function(){
$(this).stop().animate({backgroundColor:'#ffce00',width:'+=1em'},100);
});
$('#button').mouseleave(function(){
$(this).stop().animate({backgroundColor:'#1e7989',width:'-=1em'},100);
});
});

If you only want it to run one time you can unbind it after the event fires:
$(document).ready(function(){
$('#button').mouseenter(function(){
$(this).animate({backgroundColor:'#ffce00',width:'+=1em'},100);
$(this).unbind('mouseenter');
});
$('#button').mouseleave(function(){
$(this).animate({backgroundColor:'#1e7989',width:'-=1em'},100);
$(this).unbind('mouseleave');
});
});

how do I stop the query animation que when a nav button is clicked

What I want: I created a sort of image gallery with a thumbnail slider and I want the thumbnails to scroll when a nav button is clicked but if the button is pushed again before the animation is completed it doesn't keep adding to the que, it clears the que and only completes the current animation.
What my problem is: When the button is clicked it puts the click animation in a que and completes all the clicks in order. Maybe someone can help we word this better.
What I have tried: I have tried adding .finish() and .stop(true, true) to my js file but I can't seem to get it working right. I'm probably putting it in the wrong spot or even using the wrong thing, I don't know and so I need some help.
Here is a functioning jsfiddle: http://jsfiddle.net/ma9j6o09/2/
Some of it is not working since my images are locally hosted but the slider part for the thumbnails is.
This is my function for animating the movement; what do I add to get the effect I need?
var clicks = 0;
$("#right").click(function() {
if ( clicks < 5 ) {
clicks++;
$("#thumbContainer").animate({
left: "-=128px"
}, 500, function() {
// Animation complete.
});
}
});
$("#left").click(function() {
if (clicks > 0) {
clicks--;
$("#thumbContainer").animate({
left: "+=128px"
}, 500, function() {
// Animation complete.
});
}
});
Try this out: http://jsfiddle.net/ma9j6o09/3/
In response to your question about .stop() you would use it like this:
$("#thumbContainer").stop(true, true).animate({
left: "+=128px"
}, 500, function() {
// Animation complete.
});
});
But this will indeed not achieve what you want as it means it will stop the animation and jump to the last frame straight away so you lose the animation you wanted.
Instead use the flag I used in the fiddle which makes it impossible to even try animate whilst an animation is in progress.
var clicks = 0,
animating = false;
$("#right").click(function() {
// Only animate if we are not already animating
if ( clicks < 5 && !animating ) {
animating = true;
clicks++;
$("#thumbContainer").animate({
left: "-=128px"
}, 500, function() {
animating = false; // No longer animating
// Animation complete.
});
}
});
$("#left").click(function() {
// Only animate if we are not already animating
if (clicks > 0 && !animating) {
animating = true;
clicks--;
$("#thumbContainer").animate({
left: "+=128px"
}, 500, function() {
animating = false; // No longer animating
// Animation complete.
});
}
});

How to prevent mouseenter event action with jQuery

I have this simple mouseenter : mouseleave action:
call = $('.js-call');
call.on({
mouseenter: function(e){
// animation
e.stopPropagation();
},
mouseleave: function(e){
// animation
}
});
In this action i have two CSS animations, which have a duration of 300ms. How can I prevent mouseover event for animation end, and fire it again if i'm properly on call element. When i moving fast on my call element action call many times. How to prevent it? Thx for help.
I would go with placing timeouts on both events, and activate the animation only if at the end of that timeout you still meet a condition. Something like that:
var timeoutIn, timeoutOut, delay = 300;
$element.hover(
function() {
if (timeoutOut){
clearTimeout(timeoutOut);
}
timeoutIn = setTimeout(function() {
// ##################
// 'MOUSEENTER' STUFF GOES HERE
// ##################
}, delay);
},
function() {
if (timeoutIn){
clearTimeout(timeoutIn);
}
timeoutOut = setTimeout(function() {
// ##################
// 'MOUSELEAVE' STUFF GOES HERE
// ##################
}, delay);
}
);
Update: I've just created a jQuery plugin called jQuery.hoverDelay.js, you can check it out here: jQuery hoverDelay.js
what you could do is use .bind( eventType [, eventData ], handler(eventObject) ).
bind the event mouseleave after you're done with the animation and vice versa. this should fix it.
Using jQuery .stop() is the correct approach.
Heres a working fiddle starting and stoping an animation with mouseenter and mousleave, without starting new animation if theres already running one.
http://jsfiddle.net/CZtLe/
function animateMe(element, color) {
element.stop(true).animate({
backgroundColor: color,
duration: 300
});
}
$(function () {
call = $('.js-call');
call.on({
mouseenter: function (e) {
animateMe($(this), '#FF0000');
e.stopPropagation();
},
mouseout: function (e) {
animateMe($(this), '#000000');
}
});
});

jQuery - hover to show sidebar, but an option to lock it

I have a side bar which when you mouseover it slides over the content, when you mouseout it slides back. All working great.
I then have a button which when you click it, it locks the sidebar in place, pushing the content behind over. Locking the sidebar in place. Also works great..
My problem is that I wish for when the sidebar to be locked, to disable the hover, and keep it in the expanded state, then when you unlock it, to go back and re-enable hovering.
Fiddle
Thanks
$('.sec-sidebar-toggle').click(function (e) {
e.preventDefault();
if ($(this).closest('.sec-sidebar').hasClass('sidebar-locked')) {
//unlocked
$(this).closest('.sec-sidebar').removeClass('sidebar-locked');
$(this).closest('.sec-sidebar').stop().animate({
width: '38px'
}, 300).css({
'overflow': 'visible'
});
} else {
//locked
$(this).closest('.sec-sidebar').addClass('sidebar-locked');
$(this).closest('.sec-sidebar').stop().animate({
width: '253px'
}, 300).css({
'overflow': 'visible'
});
}
});
//Hover
$('.sec-sidebar').mouseover(function () {
$(this).find('.sec-nav').stop().animate({
marginLeft: '0px'
}, 300);
}).mouseout(function () {
$(this).find('.sec-nav').stop().animate({
marginLeft: '-215px'
}, 300);
});
You can unbind the mouseover and mouseout events.
http://jsfiddle.net/3n1gm4/VEUe9/
$('.sec-sidebar-toggle').click(function(e){
e.preventDefault();
if( $(this).closest('.sec-sidebar').hasClass('sidebar-locked') ){
//unlocked
$(this).closest('.sec-sidebar').removeClass('sidebar-locked');
$(this).closest('.sec-sidebar').stop().animate({width: '38px'}, 300).css({'overflow': 'visible'});
// ADD EVENT HANDLERS
setupHover();
} else{
//locked
$(this).closest('.sec-sidebar').addClass('sidebar-locked');
$(this).closest('.sec-sidebar').stop().animate({width: '253px'}, 300).css({'overflow': 'visible'});
// REMOVE EVENT HANDLERS
$('.sec-sidebar').unbind('mouseover');
$('.sec-sidebar').unbind('mouseout');
}
});
function setupHover() {
//Hover
$('.sec-sidebar').mouseover(function(){
$(this).find('.sec-nav').stop().animate({marginLeft: '0px'}, 300);
}).mouseout(function(){
$(this).find('.sec-nav').stop().animate({marginLeft: '-215px'}, 300);
});
}
setupHover();
I have wrapped the mouseout function in an IF statement to check whether the sidebar has the sidebar-locked class. If it does the following animation will not be executed.
if(!$('.sec-sidebar').hasClass('sidebar-locked')){
$(this).find('.sec-nav').stop().animate({marginLeft: '-215px'}, 300);
}
Is this what you were hoping to achieve?
Here is the JsFiddle.
Note: The ! at the start of the IF statement is to say IF NOT. So, If not this class in the above example.
There are two easy solutions in my head.
1: You could check the classes of the sidebar if 'sidebar-locked' is present with .hasClass() in the mouseevents.
2: You could remove the mouse events completely by unbinding them when you lock it and rebinding them when you unlock it.
See jQuery API: unbind.
Sidenote:
Consider using the hover event instead of the two seperate mouse events.
You should to clear mouseover event handler, and reassign it back when it needs.
Remove an event handler.

jQuery Animations Control Sequence

I'm am attempting to build a homepage that has animations. I am having hard time controlling my animations though. All I need is to hide elements, and then show elements after a certain time. Loop through that sequence, and pause and show all elements when the someone hovers over the box. Example simple animation.
I have a long way to go. At first I tried using the .css() visibility property, now I'm using .show() and .hide().
I need a way to loop through my animations. I attempt to add another
setTimeout(clear1(), 3000);
to the end of my box1 function, but that wouldn't work for some reason.
I need a way to on a user hover over #box1, that all animations stop. I have tried using .clearQueue, but I couldn't get that to work.
First of all, set to your css:
.box {display: none;}
SHOW ALL BOXES ON HOVER See Demo
This will show all boxes on hover and then continue the animation from where it stopped (will hide the boxes that hadn't shown up during the animation). I think that is what you are after.
var index = 0; // To keep track of the last div showed during animation
var time_of_delay = 1000; // Set the time of delay
// Start the animation
$(document).ready(function () {
box1(time_of_delay);
});
// The hover states
$("#box1_1").hover(
function() {
box1(0);
}, function() {
box1(time_of_delay);
});
// The animation function
function box1 (delay_time) {
var time=delay_time;
if(time>0) {
$(".box").slice(index).each(function() {
$(this).hide().delay(time).show(0);
time=time+time_of_delay;
});
index=0;
} else {
$(".box:visible").each(function() {
index++;
});
$(".box").stop(true).show(0);
}
}
PAUSE ON HOVER See Demo
This will only pause the animation and continue from where it stopped.
var time_of_delay = 1000; // Set the time of delay
// Start the animation
$(document).ready(function () {
box1(time_of_delay);
});
// The hover states
$("#box1_1").hover(
function() {
box1(0);
}, function() {
box1(time_of_delay);
});
// The animation function
function box1 (delay_time) {
var time=delay_time;
if(time>0) {
$(".box:hidden").each(function() {
$(this).delay(time).show(0);
time=time+time_of_delay;
});
} else {
$(".box").stop(true);
}
}
I used setTimeout and clearTimeout and periodically call a function that increments (and resets) the box to display. Since I assign setTimout to boxt, I am able to call clearTimeout(boxt) on box1's hover event so that I can stop specifically that loop. Here's my jsfiddle. It might not be the exact effect you're trying to achieve, but it should be the right functionality and be easily adaptable with a few tweaks. Let me know if this works for you and if you have any questions about how it works :)
LIVE DEMO
var $box = $('#box1').find('.box'),
boxN = $box.length,
c = 0,
intv;
$box.eq(c).show(); // Show initially the '0' indexed .box (first one)
function loop(){
intv = setInterval(function(){
$box.eq(++c%boxN).fadeTo(400,1).siblings().fadeTo(400,0);
},1000);
}
loop(); // Start your loop
$('#box1').on('mouseenter mouseleave', function( e ){
return e.type=='mouseenter' ? (clearInterval(intv))($box.fadeTo(400,1)) : loop();
});
Where ++c%boxN will take care to loop your animation using the Modulo % (reminder) operator inside a setInterval. Than all you need to do is to register a mouseenter and mouseleave on the parent element to:
clear the Interval on mouseenter + fade all your elements
restart your loop function on mouseleave.
Here's one way to do it:
// hide all of the boxes
$('.box').hide();
// reference to each box, the current box in this list and a flag to stop the animation
var divs = box1.getElementsByClassName('box');
var i = 0;
var run = true;
// this will animate each box one after the other
function fade(){
if(i < divs.length && run){
$(divs[i++]).fadeIn(500, function(){
setTimeout(fade, 1000);
});
}
};
fade();
// stop the above function from running when the mouse enters `box1`
$('#box1').on('mouseenter', function(){console.log('enter');
run = false;
});
// start the function again from where we stopped it when the mouse leaves `box1`
$('#box1').on('mouseleave', function(){console.log('leave');
run = true;
fade();
});

JQuery drop down, remain down while hover over drop down

I setup a jquery dropdown menu that works perfect. It drops down when a user rolls over a link. The problem is that when the user rolls over the content area of the drop down menu, it slides back up. I need to set up the code so that the slidedown box remains in the down position while the user's cursor is still over it.
Here is my HTML:
<ul id="tabnav">
<li class="tab2">My Leases</li>
</ul>
<div id="leases">
<!-- slide down content here -->
</div>
JS Trigger:
<script type="text/javascript">
$(document).ready(function(){
$(".btn-slide").hover(function(){
$("#leases").slideToggle("medium");
$(this).toggleClass("active");
return false;
});
});
</script>
Any ideas?
EDIT: Here is a link to page in question: http://designvillain.com/testbed/600/601.html
I'm not sure if this is what you want, but I'll just drop it here. It waits 500ms before sliding up #leases, and only when appropriate
var isMousedOver;
var hideDropdown = function(a) {
setTimeout( function() {
if (isMousedOver) return;
$("#leases").slideUp("medium");
$(a).removeClass("active");
}, 500);
}
$(".btn-slide").hover(
function(){
$("#leases").stop(true,true).slideDown("medium");
isMousedOver = true;
$(".btn-slide").removeClass("active");
$(this).addClass("active");
var that = this;
$("#leases").data("mouseoutfn", function() { hideDropdown(that) });
},
function(){
isMousedOver = false;
hideDropdown(this);
}
);
$("#leases").hover(
function() {
isMousedOver = true;
},
function() {
isMousedOver = false;
$(this).data("mouseoutfn")();
}
);
Here's a demo: http://jsfiddle.net/mMRZc/
The .hover() binds two events, mouseenter and mouseleave.
I would instead go granular and use the mouseenter() on the .btn-slide and the mouseleave() on the .leases
$(function()
{
$(".btn-slide").mouseenter(function(){
$("#leases").slideToggle("medium");
$(this).toggleClass("active");
});
$("#leases").mouseleave(function(){
$(".btn-slide").toggleClass("active");
$(this).slideToggle("medium");
});
});
EDIT: Note, if the mouse never enters the #leases div, it will not get the mouseleave, and you may need to consider that.
EDIT2: fix my bad finger typing of funciton to function
I assume the div is hidden on page load and you want it to show when you hover over the link? Change toggle to down...
$(document).ready(function(){
$("#leases").hide();
$(".btn-slide").hover(function(){
$("#leases").slideDown("medium");
$(this).toggleClass("active");
return false;
});
});
Does it need to slide back up sometime?
