I'm trying to rotate a fixed image in sync with fullpage.js and it works for the most part.
In order to prevent unwanted rotation I have to stack css rotate() values.
It works when I scroll down and it stacks as I wanted (ie. 180, 360, 540, ..)
It doesn't work when I scroll up.
I tried to use alerts to identify if the calculation is done, there seems to be no problem on the stacking, but scroll up portion of the code simply doesn't print to the HTML document.
Here's my code;
var rotation = 0,
rotationInc = 180,
miniLogo = $('#mini-logo');
$(document).ready(function () {
$('#home').fullpage({
verticalCentered: false,
scrollingSpeed: 300,
onLeave: function (index, nextIndex, direction) {
if (direction == 'down') {
rotation += rotationInc;
setTimeout(function () {
miniLogo.addClass('enlarge');
}, 400);
miniLogo.each(function () {
alert(rotation);
});
setTimeout(function () {
miniLogo.css({
'transform': 'rotate(' + rotation + 'deg)'
});
}, 800);
setTimeout(function () {
miniLogo.removeClass('enlarge');
}, 1200);
}
if (direction == 'up') {
rotation -= rotationInc;
setTimeout(function () {
miniLogo.addClass('enlarge');
}, 400);
miniLogo.each(function () {
alert(rotation);
});
setTimeout(function () {
miniLogo.css({
'transform': 'rotate(' + rotation + 'deg);'
});
}, 800);
setTimeout(function () {
miniLogo.removeClass('enlarge');
}, 1200);
}
}
});
});
The first if statement works perfectly. The second gives the alert I wanted but doesn't print the reduced degree on the html.
Any help would be much appreciated, I'm sure I've done a rookie mistake.
Try this :
rotation = 0;
rotationInc = 180;
miniLogo = $('#mini-logo');
$(document).ready(function () {
$('#home').fullpage({
verticalCentered: false,
scrollingSpeed: 300,
onLeave: function (index, nextIndex, direction) {
var rotation = (direction == 'down')
? rotation += rotationInc
: rotation -= rotationInc;
setTimeout(function () {
miniLogo.addClass('enlarge');
}, 400);
miniLogo.each(function () {
alert(rotation);
});
setTimeout(function () {
miniLogo.css({
'transform': 'rotate(' + rotation + 'deg)'
});
}, 800);
setTimeout(function () {
miniLogo.removeClass('enlarge');
}, 1200);
}
}
});
});

I try to call angular function in ngAfterViewInit()
ngAfterViewInit() {
this.gagSlider();
}
gagSlider() function
gagSlider(){
$.fn.animateRotate = function(angle, duration, easing, complete) {
alert(1);
return this.each(function() {
var $elem = $(this);
$({deg: 0}).animate({deg: angle}, {
duration: duration,
easing: easing,
step: function(now) {
$elem.css({
transform: 'rotate(' + (-90 + ((90 * 180) / 100)) + 'deg)'
});
},
complete: complete || $.noop
});
});
};
$('.meter-clock').animateRotate(0);
}
I am getting alert successfully but rotate not working
I'm simulating a bowling game in jQuery. So, I throw the ball (through animate function) and when it hits a pin I simulate it falling over (also through animate function). But I can only make it rotate. I want it to fall over in place, to the left or to the right. Like this. This is the jQuery code for the pin animation:
this.animation = function (pinID) {
var rdm = ((Math.random()*10)+1);
var degree;
if (rdm <= 5)
degree = -90;
else
degree = 90;
$(pinID).animate({ deg: degree },
{
duration: 1000,
step: function (now) {
// In the step-callback (that is fired each step of the animation),
// the pin will rotate to the current degree of the animation
$(pinID).css({
transform: 'rotate(' + now + 'deg)'
});
},
complete: function () {
// When the animation is complete, removes the pin from play
$(pinID).css({
"left": -200, "top": -200
});
}
});
}
I tried to have a left and top in the beginning of the animate function the it just simulated a weird movement.
I'd appreciate it if anyone could help me. Thanks.
EDIT Here's the result (thanks to Zs V):
this.animation = function (pinID) {
if (knockedPins.indexOf(pinID) == -1) {
var rdm = ((Math.random() * 10) + 1);
var degree;
var transFormOrigin;
if (rdm <= 5) {
degree = -90;
transFormOrigin = '0% 100%';
}
else {
degree = 90;
transFormOrigin = '100% 100%';
}
$(pinID).css({ "transform-origin": transFormOrigin });
knockedPins.push(pinID);
$(pinID).animate({ deg: degree },
{
duration: 1000,
step: function (now) {
// In the step-callback (that is fired each step of the animation),
// the pin will rotate to the current degree of the animation
$(pinID).css({
transform: 'rotate(' + now + 'deg)'
});
},
complete: function () {
// When the animation is complete, removes the pin from play
$(pinID).css({
"left": -200, "top": -200
});
}
});
}
}
I added the transform-origin property and had to make use of an array to store the ids of the pins that were already knocked, otherwise it would shake until it was put to rest. hehe
You have to rotate the object (the picture) around its corner instead of the center. Here it is a discussion how to do that: https://stackoverflow.com/a/6633676/6624619
I am trying to implement rotate animation its working but I want to change the div position. Here is my code:-
$(function(){
var el=$('div');
el.animate({ deg: 180 }, {
duration: 1000,
step: function (now) {
el.css({
transform: 'rotate(' + now + 'deg)'
});
},
complete: function () {
},
});
});
Fiddle Demo
I want this position(now its first but I want second):-
Thanks for your hepl
Use translateY(-100%)
$(function(){
var el=$('div');
el.animate({ deg: 180 }, {
duration: 1000,
step: function (now) {
el.css({
transform: 'rotate(' + now + 'deg) translateY(-100%)'
});
},
complete: function () {
},
});
});
DEMO
$(function(){
var el=$('div');
var topik = $('div').css('top');
el.animate({ deg: 180 }, {
duration: 1000,
step: function (now) {
el.css({
transform: 'rotate(' + now + 'deg)',
top : topik+'500px',
});
},
complete: function () {
},
});
})
Dont thank me ;););)
I've been trying to figure out how to get this script to rotate an image infinitely onclick and then stop it when you click it again. Can anyone modify it to get it to do that?
$(function() {
var $rota = $('.spin'),
degree = 0,
timer;
function rotate() {
$rota.css({ transform: 'rotate(' + degree + 'deg)'});
// timeout increase degrees:
timer = setTimeout(function() {
++degree;
rotate(); // loop it
},5);
}
rotate(); // run it!
});
you could create a bool to determine if the element has been clicked, change it on click and stop the process if the click has happened.
$(function() {
var $rota = $('.spin'),
degree = 0,
clicked = false,
timer;
$rota.on('click', function() { clicked = true; return false; } );
function rotate() {
if ( clicked )
$rota.css({ transform: 'rotate(' + degree + 'deg)'});
// timeout increase degrees:
timer = setTimeout(function() {
++degree;
rotate(); // loop it
},5);
}
rotate(); // run it!
});
Try using setInterval and clearInterval instead of setTimeout:
function rotate() {
$rota.css({ transform: 'rotate(' + degree + 'deg)'});
++degree;
}
var loop;
$rota.click(function() {
if(loop) {
clearInterval(loop);
loop = false;
}
else {
loop = setInterval(rotate, 5);
}
});
You can read up on setInterval here
Try
$(function() {
var $rota = $('.spin')
$rota.click(function(){
var $this = $(this);
if($this.data('rotating')){
clearInterval($this.data('rotating'));
$this.data('rotating', false)
} else {
$this.data('rotating', setInterval(function(){
var degree = $this.data('degree') || 0;
$this.css({ transform: 'rotate(' + degree + 'deg)'});
$this.data('degree', ++degree)
}, 5));
}
});
});
Demo: Fiddle
$(function() {
var $rota = $('img'), degree = 0, timer, enabled;
var rotate = function() {
timer = setInterval(function() {
++degree;
$rota.css({
transform: 'rotate(' + degree + 'deg)'
});
},5);
};
$rota.on('click', function(){
enabled = !enabled;
enabled ? rotate() : clearInterval(timer);
});
});
Has anyone set up a nivo slider to pan each image (aka Ken Burns effect)? I'm trying to implement it and it's kinda tricky!
Actually, I got my implementation working!
I have a panning function loop.. something like this:
function ken_burns_loop(el) {
$(el)
.animate({
'background-position-x': '40%',
'background-position-y': '60%'
}, 8000, 'linear')
.animate({
'background-position-x': '30%',
'background-position-y': '40%'
}, 8000, 'linear')
.animate({
'background-position-x': '70%',
'background-position-y': '70%'
}, 8000, 'linear', function() { ken_burns_loop(el); });
}
And I'm initializing nivo slider like this:
$('#welcome-slider').nivoSlider({
effect: 'fade',
slices: 1,
directionNav: false,
afterChange: function() {
$('#welcome-slider, .nivo-slice').stop(true);
ken_burns_loop('#welcome-slider, .nivo-slice');
}
});
ken_burns_loop('#welcome-slider, .nivo-slice');
I'm still working out some problems with positioning.
Source & Demo
Add this to your JS:
if(currentEffect === 'kenburns'){
createZoom(slider, settings, vars);
zoom = $('.nivo-zoom:last', slider);
var delta = (8 + Math.random() * 2) / 100;
var neww = zoom.width() * (1 + delta);
var newh = zoom.height() * (1 + delta);
var x = delta * zoom.width(); //Math.random()*(neww-zoom.width());
var y = delta * zoom.height(); //Math.random()*(newh-zoom.height());
var zoomdir = Math.round(Math.random() * 4);
zoom.animate({ opacity:'1.0'}, {easing:'linear',duration:settings.pauseTime*2/3});
if(zoomdir == 1) {
zoom.find('img').animate({ height:newh+'px',width:neww+'px',left: '-'+x+'px',top: '-'+y+'px'},{easing:'linear',duration:settings.pauseTime*4/3, complete: function(){ slider.trigger('nivo:animFinished'); }});
} else if(zoomdir == 2) {
zoom.find('img').animate({ height:newh+'px',width:neww+'px',right: '-'+x+'px',top: '-'+y+'px'}, {easing:'linear',duration:settings.pauseTime*4/3, complete: function(){ slider.trigger('nivo:animFinished'); }});
} else if(zoomdir == 3) {
zoom.find('img').animate({ height:newh+'px',width:neww+'px',right: '-'+x+'px',bottom: '-'+y+'px'}, {easing:'linear',duration:settings.pauseTime*4/3, complete: function(){ slider.trigger('nivo:animFinished'); }});
} else {
zoom.find('img').animate({ height:newh+'px',width:neww+'px',left: '-'+x+'px',bottom: '-'+y+'px'}, {easing:'linear',duration:settings.pauseTime*4/3, complete: function(){ slider.trigger('nivo:animFinished'); }});
}
if($('.nivo-zoom', slider).length > 2) $('.nivo-zoom:first', slider).remove();
}
