How To Toggle Back To Original State

My Script Snippet:
$(document).on('click', function(e) {
if ($(e.target).closest('.input-actions.Actions').length) {
var CurrentWidth = $(e.target).width() + 'px',
OpenWidth = '308px';
if ($(e.target).is('.dropdown-toggle')) {
$(e.target).animate({
width:OpenWidth
}, {
direction: 'right',
duration: 500,
});
setTimeout(function() {
$(e.target).parent().find('.dropdown-menu').slideDown({
height: '249px',
}, {
duration: 500,
});
}, 800);
}
}
});
Script Explanation:
On click of the link, the button changes with to match the drop down via animate then with the delay the drop down slides down.
What I'd Like To Achieve:
I'd like to add, in the most simplistic way, a toggle feature so that upon clicking again the reverse occurs animating the $(e.target) back to CurrentWidth and $(e.target).parent().find('.dropdown-menu') to slide back up and hide.

Back to top button not triggering properly

I have a back to top button that appears when you scroll a little bit .It's working fine but when scrolling if I get to the footer i want the button to go above the footer.
I used the jquery animate method to change the bottom css rule of the button when I get to the bottom of the page.But that effect doesn't happen instantly on my website because i have more javascript and i think it needs to go through all the code before it runs the effect and It's just not working properly.
Where is the problem ? .Here is what I have done : JSFIDDLE
var offset = 250;
var duration = 500;
$(window).scroll(function () {
if ($(this).scrollTop() > offset) {
$('.back-to-top').fadeIn(duration);
} else {
$('.back-to-top').fadeOut(duration);
}
});
$('.back-to-top').on('click', function () {
event.preventDefault();
$('html,body').animate({ scrollTop: 0 }, duration);
return false;
});
$(window).scroll(function () {
if ($(window).scrollTop() + $(window).height() == $(document).height()) {
$('.back-to-top').animate({ 'bottom': '400px' });
} else $('.back-to-top').animate({ 'bottom': '10%' });
});

It seems like adding a class that changes the position of the div, and toggling it when the condition is true solved the problem .

Stop/reverse animation on mouse off (baraja jquery plugin)

I've implemented the baraja jquery plugin for a section on a 'web app' that I need to create.
Rather than the plugin spreading the cards on the click of a button, I've opted to alter the script and spread out the cards on hover. On the face of it this works but if you hover over the cards and back off quickly before the animation is finished the cards will stay open. And then when you hover over the 'deck' they close. I've created a codepen below to show this:
http://codepen.io/moy/pen/OPyGgw
I've tried using .stop(); but it doesn't seem to have an impact on the result. Can anyone help me with this?
Additionally I'd like the deck to be open on page load, then close after a second or 2. I tried this with $( document ).ready() including the baraja.fan call but that didn't trigger it - any ideas?

this one really tickled me ;) tried several things, but - as already told - the plugin doesn't expect to get the close animation call faster, then the opening animation will run.
so finally i build you the following.
- opening the fan, right at document ready
- created a timeout for the mouseleave, to wait for the opening animation duration, before closing it - you will have a 400ms delay when mouseleave the element, but it will close, even when you've been to fast...
$(document).ready(function () {
if ($("#baraja-el").length) {
var $el = $('#baraja-el');
baraja = $el.baraja();
}
//initial open
baraja.fan({
speed: 400,
easing: 'ease-in-out',
range: 80,
direction: 'right',
origin: {
x: 0,
y: 0
},
center: true
});
$('.baraja-container').addClass('open');
// navigation
$('#baraja-prev').on('click', function (event) {
baraja.previous();
$('.baraja-container li').each(function () {
if ($(this).css('z-index') === "1000") {
$(this).addClass('visited');
}
});
});
$('#baraja-next').on('click', function (event) {
baraja.next();
$('.baraja-container li').each(function () {
if ($(this).css('z-index') === "1010") {
$(this).addClass('visited');
}
});
});
$('.baraja-container').hover(function (event) {
if(!$(this).hasClass('open'))
{
$(this).addClass('open');
baraja.fan({
speed: 400,
easing: 'ease-in-out',
range: 80,
direction: 'right',
origin: {
x: 0,
y: 0
},
center: true
});
}
}, function (event) {
curBarCon = $(this);
setTimeout(function(){
curBarCon.removeClass('open');
baraja.close();
}, 400);
});
$('.baraja-container li').click(function () {
$(this).addClass('visited');
});
});
since i fiddled in your codepen, you should have the working version here: http://codepen.io/moy/pen/OPyGgw
but... it's really no perfect solution. i'd suggest to get another plugin or rework baraja to get callback functions, which would test if the animation is currently running and dequeue them if needed.

jQuery Slideup and Fadein Effect at the same Time

I'm learning new stuff with jQuery here and I have seen a effect that I like link here
Meet my Team section. As you can see if you scroll down the circle slidesup and fades in at the same time. I tried to replicate that effect. Here's my jsfiddle
$(window).on("scroll", function() {
if ($(window).scrollTop() >= $('#thumbnails-cont').offset().top-$(window).height()) {
$("#thumbnails img").animate({opacity: 1, bottom: 0})
}
});

You have to work with the queue property to play animations simultaneously.
Working fiddle: Here
Basic code:
$(function() {
$(".thumbnail").animate({ opacity: 1 }, { duration: 1200, queue: false });
$(".thumbnail").animate({ "margin-top": "0px" }, { duration: 1200, queue: false });
});
Read this for more information about the animation function in jQuery.
I hope I could help you a bit :)

Submenu animation "pops up"

I have a menu with sub items inside it. In order to make animation effect I want, I need to retrieve sub-menu width,height and height of its first-child. Now my animation works ,but sometimes my sub-menu just "pops up" (it doesn't animate its width ).
Here is The Fiddle of the problem.
http://www.vasinternetposao.com/wordpressdevelopment/wp-content/themes/override/images/submenu_problem.png
I am using this code:
var j = jQuery.noConflict();
j(document).ready(function () {
j('ul.nav').removeClass('nav').addClass('jnav'); //Add jquery Class to our menu
j('ul.jnav li').hover(function () {
if (j(this).children('ul:first').hasClass('jsub-menu')) { //Let's check if "jsub-menu" Class is here
return false; //If it is ("jsub-menu" here) don't SlideDown...
} else { //Else slide down if no class
j(this).find('ul.sub-menu:first').not(':animated').slideDown(500);
}
}, function () {
j(this).find('ul:first').slideUp(500, function () {
j(this).removeClass('jsub-menu').addClass('sub-menu');
j(this).css({
'height': '',
'width': ''
});
});
});
j('ul.jnav ul.sub-menu a').hover(function () {
j(this).addClass('active');
if (j('.active').next('ul.sub-menu').length) { //If submenu exist...
j('.active').next('ul.sub-menu').css({
'visibility': 'hidden',
'opacity': '0',
'display': 'block'
}); //Show it so we can read its:
var get_width = j('.active').next('ul.sub-menu').outerWidth(true); //WIDTH
var get_height_of_first_child = j('.active').next('ul.sub-menu').children('li:first').outerHeight(true); //HEIGHT of its First Child
var get_submenu_height = j('.active').next('ul.sub-menu').outerHeight(true); //HEIGHT of our menu
j('.active').next('ul').removeClass('sub-menu') //Remove class from menu, add another class apply HEIGHT of FIRST CHILD and hide it again...
.addClass('jsub-menu').css({
'visibility': '',
'opacity': '',
'height': get_height_of_first_child + 'px',
'width': '0'
});
j('.active').next('.jsub-menu').animate({
width: get_width
}, 1000, function () { //Animate WIDTH
j('.active').next('.jsub-menu').animate({
height: get_submenu_height
}, 1000); //callback animate HEIGHT
});
} //End if
}, function () {
j('.active').removeClass('active');
});
});
I think that this is happening because my Slide Up/Down animations are conflicting with my animate with/height functions but I am not sure. I have tried to solve it by adding stop(),stop(true,true),stop(true,false) in numerous combinations but failed. I am trying to solve this for days now so you stackers are my only hope. Please help!
Thank you!!

I was finally able to replicate the error.
I wrote this code for you, to replace the code you have for the animation.
var animating = false;
function animate($elm, options, callback) {
if (animating)
return;
animating = true;
$elm.animate(options, 1000, function() {
animating = false;
if (callback != undefined)
callback();
});
}
Call it like this, from inside your hover callback.
animate(j('.active').next('.jsub-menu'),
{
'width': get_width,
'height' : get_submenu_height
});
Basically, it checks if another animation is already running, in which case it doesn't start it. The Flag is set to false when the animation stopped, and let's other animations go on.
You can also pass a callback to do something after the animation is completed, but in your case you don't need it, because you can animate the height and width in the same time.
I tested it for like a minute and it looked pretty smooth.
Here is the updated feedle: http://jsfiddle.net/gabrielcatalin/TNxJ4/1/
P.S. You may also want to use the $ sign instead of 'j' for jQuery wrappers.
