Smoothstate.js - removeClass not working onReady function

I'm using Smoothstate.js to add page transitions to my website and I'm trying to show a loading page between each page transition using the onStart, onProgress and onReady functions.
The code I have works, but every now and again it get's stuck on the loading page and the container div isn't removing the class 'is-loading'. However, it is removing the is-exiting class even though they're with the same removeClass line?
I'm so confused as to why It's not removing. Can anyone help please?
// Photoswipe
$(function(){
'use strict';
var options = {
prefetch: true,
debug:true,
cacheLength: 0,
repeatDelay: 500,
onStart: {
duration: 0, // Duration of our animation
render: function ($container) {
// Add your CSS animation reversing class
$container.addClass('is-exiting');
// Restart your animation
smoothState.restartCSSAnimations();
}
},
onProgress: {
// How long this animation takes
duration: 0,
// A function that dictates the animations that take place
render: function ($container) {
setTimeout(function() {
$container.addClass('is-loading');
$('#progressBar').append('<div id="bar"></div>');
var progress = '100%';
$('#bar').animate({
width: progress
}, 400);
}, 500);
}
},
onReady: {
duration: 0,
render: function ($container, $newContent) {
$container.removeClass('is-loading is-exiting');
// Inject the new content
$container.html($newContent);
},
},
onAfter: function() {
navbarAnimate();
closeMenu();
ImageSliders();
initPhotoSwipeFromDOM('.gallery');
ImageOverlay();
}
},
smoothState = $('#main').smoothState(options).data('smoothState');
});

Just a hint:
you add is-loading, 500ms after the loading process started. So may it be possible that onReady gets fired before your 500ms timeout? And therefore is-loading will be added as class again, after your removeClass call?
tl;dr: the problem is most likely the timeout here
setTimeout(function() {
$container.addClass('is-loading');
$('#progressBar').append('<div id="bar"></div>');
var progress = '100%';
$('#bar').animate({
width: progress
}, 400);
}, 500);

smoothState.js: Add class to #main wrapper

I am using smoothStates default settings and I wanted to know if I can add a class to the main wrapper so I can change the background color of the site? I don't want to add another div under main as its just extra markup.
At the moment I can only add page-index and then the rest of the pages don´t change as smoothState doesn't load the page again.
EDIT: So I want to add a class for each page, like: page-index, page-about and so on.
I have a div like so:
<div id="main">
// stuff here
</div>
When you click on /news:
<div id="main" class="page-news">
// stuff here
</div>
My functions:
$(function(){
'use strict';
var options = {
prefetch: true,
cacheLength: 2,
onStart: {
duration: 250, // Duration of our animation
render: function ($container) {
// Add your CSS animation reversing class
$container.addClass('is-exiting');
// Restart your animation
smoothState.restartCSSAnimations();
}
},
onReady: {
duration: 0,
render: function ($container, $newContent) {
// Remove your CSS animation reversing class
$container.removeClass('is-exiting');
// Inject the new content
$container.html($newContent);
}
}
},
smoothState = $('#main').smoothState(options).data('smoothState');
});

To achieve what you want, you can use onAfter.
The function to run when the new content has been injected into the page and all animations are complete. This is when to re-initialize any plugins needed by the page.
Create a function:
function addClass() {
$('#main').addClass('your_class second_class');
};
Then inject this into your smoothState initialization:
$(function(){
'use strict';
var options = {
prefetch: true,
cacheLength: 2,
onStart: {
duration: 250, // Duration of our animation
render: function ($container) {
// Add your CSS animation reversing class
$container.addClass('is-exiting');
// Restart your animation
smoothState.restartCSSAnimations();
}
},
onReady: {
duration: 0,
render: function ($container, $newContent) {
// Remove your CSS animation reversing class
$container.removeClass('is-exiting');
// Inject the new content
$container.html($newContent);
}
},
onAfter: function($container, $newContent) {
addClass();
}
},
smoothState = $('#main').smoothState(options).data('smoothState');
});
Update: How to dynamically set classes:
<!-- HTML -->
<div id="cms-classes" class="Put your classes in here">
</p>
/* CSS */
#cms-classes { display: none }
// JavaScript
function addClass() {
cmsClasses = $('#cms-classes').attr('class');
$('#main').addClass(cmsClasses);
};
Hope this helps!

jQuery animation setup callback throws error

I want to implement a jQuery animation callback method progress or step,
but in either case I'm getting the following error:
NS_ERROR_IN_PROGRESS: Component returned failure code: 0x804b000f (NS_ERROR_IN_PROGRESS) [nsICacheEntry.dataSize]
I searched a lot but not able to find anything in context, I am kind of stuck here, please suggest what could cause this error?
In fiddle i tried with step and progress and its working there , but not able to get it worked in my code, I am just looking, has some one faced such kind of error in jquery animation?
The sample code is:
this.taskHandle.find('img').stop(true, true).animate({
//todo//
top: vtop, // this.taskHandle.outerHeight(),
//'top': 0 - $('.target.upper').height(),
width: 0,
opacity: 0
}, {
duration: 2000,
step: function(){
console.log('I am called');
}
},
$.proxy(function() {
// some css clearing method
}, {
// some further actions after animation completes
})
);

You have some semantic errors going on here. I'm going to repost your code, formatted for easier reading:
this.taskHandle.find('img')
.stop(true, true)
.animate(
{
//todo//
top: vtop , // this.taskHandle.outerHeight(),
//'top' : 0 - $('.target.upper').height(),
width : 0,
opacity : 0
},
{
duration:2000,
step: function() {
console.log('I am called');
}
},
$.proxy(
function() {
// some css clearing method
},
{
// some further actions after animation completes
}
)
);
First: animate() doesn't accept 3 parameters (at least not those 3 parameters). I'm not sure what you are trying to do with your css clearing method, but anything you wan't to happen after the animation is complete should be in the complete method that you add right next to the step method.
Second: $.proxy() needs to have the context in which you want it to run as the second parameter, not some other"complete"-function.
So here is a slightly modified example which works. You can try it yourself in this fiddle.
var vtop = 100;
$('div')
.stop(true, true)
.animate(
{
top: vtop,
width: 0,
opacity : 0
},
{
duration: 2000,
step: function() {
console.log('I am called');
},
complete: function () {
alert('complete');// some further actions after animation completes
}
}
);

You could use Julian Shapiro's Velocity.js, which animations are (arguable) faster than jQuery and CSS (read this for more)
It allows you to use callbacks such as :
begin
progress
complete
like :
var vtop = 100;
jQuery(document).ready(function ($) {
$('div').find("img").velocity({
top: vtop,
width: 0,
opacity: 0
}, {
duration: 2000,
begin: function (elements) {
console.log('begin');
},
progress: function (elements, percentComplete, timeRemaining, timeStart) {
$("#log").html("<p>Progress: " + (percentComplete * 100) + "% - " + timeRemaining + "ms remaining!</p>");
},
complete: function (elements) {
// some further actions after animation completes
console.log('completed');
$.proxy( ... ); // some css clearing method
}
});
}); // ready
Notice that you just need to replace .animate() by .velocity()

How to get image to pulse with opacity with JQuery

I am trying to get an image to change opacity smoothly over a duration of time. Here's the code I have for it.
<script type="text/javascript">
pulsem(elementid){
var element = document.getElementById(elementid)
jquery(element).pulse({opacity: [0,1]},
{ duration: 100, // duration of EACH individual animation
times: 3, // Will go three times through the pulse array [0,1]
easing: 'linear', // easing function for each individual animation
complete: function() { alert("I'm done pulsing!"); }
})
</script>
<img src="waterloo.png" onmouseover="javascript:pulsem("waterloo")" border="0" class="env" id="waterloo"/>
Also, is there a way for this to happen automatically without the need of a mouseover? Thanks.

I'm assuming your code is for the jQuery pulse plugin: http://james.padolsey.com/javascript/simple-pulse-plugin-for-jquery/
If your above code is not working, then fix "jquery" to be "jQuery".
For starting it on page load, just do:
jQuery(function() {
jQuery('#yourImageId').pulse({
opacity: [0,1]
}, {
duration: 100, // duration of EACH individual animation
times: 3, // Will go three times through the pulse array [0,1]
easing: 'linear', // easing function for each individual animation
complete: function() {
alert("I'm done pulsing!");
}
});
Add an id to your image and you're golden.
});

To fire the animation of your own accord:
pulsate( $('#waterloo') );
revised code to continually pulsate (wasn't sure if this was what you're after) - the pulsate effect is relegated to it's own function so you can call it directly or in your event handler
<script type="text/javascript">
$(function() { // on document ready
$('#waterloo').hover( //hover takes an over function and out function
function() {
var $img = $(this);
$img.data('over', true); //mark the element that we're over it
pulsate(this); //pulsate it
},
function() {
$(this).data('over', false); //marked as not over
});
});
function pulsate(element) {
jquery(element).pulse({opacity: [0,1]}, // do all the cool stuff
{ duration: 100, // duration of EACH individual animation
times: 3, // Will go three times through the pulse array [0,1]
easing: 'linear', // easing function for each individual animation
complete: function() {
if( $(this).data('over') ){ // check if it's still over (out would have made this false)
pulsate(this); // still over, so pulsate again
}
}});
}
<img src="waterloo.png" border="0" class="env" id="waterloo"/>
Note - to trigger events, you can use .trigger() or the helper functions, like
$('#waterloo').mouseover() // will fire a 'mouseover' event
or
$('#waterloo').trigger('mouseover');

this might be what you're looking for.
http://www.infinitywebcreations.com/2011/01/how-to-create-a-throbbingpulsing-image-effect-with-jquery/

I personally do something like this to pulse when the mouse hovers over the image and return to full opacity on mouse out...
$(document).ready(function () {
function Pulse(Target, State) {
//Every 750ms, fade between half and full opacity
$(Target).fadeTo(750, State?1:.5, function() {Pulse(Target, !State)});
}
$("#ImageId").hover(function () {
$(this).stop()
Pulse(this);
}, function () {
$(this).stop(false, true).fadeTo(200, 1); //200ms to return to full opacity on mouse out
});
});

How to run two jQuery animations simultaneously?

Is it possible to run two animations on two different elements simultaneously? I need the opposite of this question Jquery queueing animations.
I need to do something like this...
$('#first').animate({ width: 200 }, 200);
$('#second').animate({ width: 600 }, 200);
but to run those two at the same time. The only thing I could think of would be using setTimeout once for each animation, but I don't think it is the best solution.

yes there is!
$(function () {
$("#first").animate({
width: '200px'
}, { duration: 200, queue: false });
$("#second").animate({
width: '600px'
}, { duration: 200, queue: false });
});

That would run simultaneously yes.
what if you wanted to run two animations on the same element simultaneously ?
$(function () {
$('#first').animate({ width: '200px' }, 200);
$('#first').animate({ marginTop: '50px' }, 200);
});
This ends up queuing the animations.
to get to run them simultaneously you would use only one line.
$(function () {
$('#first').animate({ width: '200px', marginTop:'50px' }, 200);
});
Is there any other way to run two different animation on the same element simultaneously ?

I believe I found the solution in the jQuery documentation:
Animates all paragraph to a left style
of 50 and opacity of 1 (opaque,
visible), completing the animation
within 500 milliseconds. It also will
do it outside the queue, meaning it
will automatically start without
waiting for its turn.
$( "p" ).animate({
left: "50px", opacity: 1
}, { duration: 500, queue: false });
simply add: queue: false.

If you run the above as they are, they will appear to run simultaenously.
Here's some test code:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
$(function () {
$('#first').animate({ width: 200 }, 200);
$('#second').animate({ width: 600 }, 200);
});
</script>
<div id="first" style="border:1px solid black; height:50px; width:50px"></div>
<div id="second" style="border:1px solid black; height:50px; width:50px"></div>

While it's true that consecutive calls to animate will give the appearance they are running at the same time, the underlying truth is they're distinct animations running very close to parallel.
To insure the animations are indeed running at the same time use:
$(function() {
$('#first').animate({..., queue: 'my-animation'});
$('#second').animate({..., queue: 'my-animation'});
$('#first,#second').dequeue('my-animation');
});
Further animations can be added to the 'my-animation' queue and all can be initiated provided the last animation dequeue's them.

See this brilliant blog post about animating values in objects.. you can then use the values to animate whatever you like, 100% simultaneously!
http://www.josscrowcroft.com/2011/code/jquery-animate-increment-decrement-numeric-text-elements-value/
I've used it like this to slide in/out:
slide : function(id, prop, from, to) {
if (from < to) {
// Sliding out
var fromvals = { add: from, subtract: 0 };
var tovals = { add: to, subtract: 0 };
} else {
// Sliding back in
var fromvals = { add: from, subtract: to };
var tovals = { add: from, subtract: from };
}
$(fromvals).animate(tovals, {
duration: 200,
easing: 'swing', // can be anything
step: function () { // called on every step
// Slide using the entire -ms-grid-columns setting
$(id).css(prop, (this.add - this.subtract) + 'px 1.5fr 0.3fr 8fr 3fr 5fr 0.5fr');
}
});
}

Posting my answer to help someone, the top rated answer didn't solve my qualm.
When I implemented the following [from the top answer], my vertical scroll animation just jittered back and forth:
$(function () {
$("#first").animate({
width: '200px'
}, { duration: 200, queue: false });
$("#second").animate({
width: '600px'
}, { duration: 200, queue: false });
});
I referred to: W3 Schools Set Interval and it solved my issue, namely the 'Syntax' section:
setInterval(function, milliseconds, param1, param2, ...)
Having my parameters of the form { duration: 200, queue: false } forced a duration of zero and it only looked at the parameters for guidance.
The long and short, here's my code, if you want to understand why it works, read the link or analyse the interval expected parameters:
var $scrollDiv = '#mytestdiv';
var $scrollSpeed = 1000;
var $interval = 800;
function configureRepeats() {
window.setInterval(function () {
autoScroll($scrollDiv, $scrollSpeed);
}, $interval, { queue: false });
};
Where 'autoScroll' is:
$($scrollDiv).animate({
scrollTop: $($scrollDiv).get(0).scrollHeight
}, { duration: $scrollSpeed });
//Scroll to top immediately
$($scrollDiv).animate({
scrollTop: 0
}, 0);
Happy coding!
