I am trying to have elements in a canvas rotate either clockwise or counter-clockwise depending on which arrow is clicked. The problem is that when you rotate one way and then another, the first click will go in the previously clicked arrow's direction on the first click.
ie. click rotate clockwise and it rotates clockwise. Then click rotate counter-clockwise and the first time you click it, the effected elements rotate clockwise on the then counter-clockwise on the second and each click afterwards. This happens in both directions.
Hope that's clear. Here, there's not much to it. Rotator code at the end:
$(document).ready(function(){
counter = 0;
//draggable
$(".drag").draggable({
helper:'clone',
containment: 'frame',
//first dragged
stop:function(ev, ui) {
var pos=$(ui.helper).offset();
objName = "#clonediv"+counter++
$(objName).css({"left":pos.left,"top":pos.top});
$(objName).removeClass("drag");
//existing dragged
$(objName).draggable({
containment: 'parent',
stop:function(ev, ui) {
var pos=$(ui.helper).offset();
console.log($(this).attr("id"));
console.log(pos.left)
console.log(pos.top)
}
});
}
});
//droppable
$("#frame").droppable({
drop: function(ev, ui) {
if (ui.helper.attr('id').search(/drag[0-9][0-9]/) != -1){
counter++;
var element=$(ui.draggable).clone();
element.addClass("tempclass");
$(this).append(element);
$(".tempclass").attr("id","clonediv"+counter);
$("#clonediv"+counter).removeClass("tempclass");
draggedNumber = ui.helper.attr('id').search(/drag([0-9][0-9])/)
itemDragged = "dragged" + RegExp.$1
console.log(itemDragged)
$("#clonediv"+counter).addClass(itemDragged);
$("ol").append($("div").attr("data-piece") + "<br>" );
}
}
});
//trash can
$("#trash").droppable({
greedy: 'true',
accept: function() { return true; },
drop: function (event, ui) {
tolerance: 'fit', $(ui.draggable).remove();
$("ol").detach();
}
});
//rotator
var angle = 22.5;
$('#spin').click(function() {
$('.drag').css ({
'-webkit-transform': 'rotate(' + angle + 'deg)',
'-moz-transform': 'rotate(' + angle + 'deg)',
'-o-transform': 'rotate(' + angle + 'deg)',
'-ms-transform': 'rotate(' + angle + 'deg)'
});
angle+=22.5;
});
$('#spin2').click(function() {
$('.drag').css ({
'-webkit-transform': 'rotate(' + angle + 'deg)',
'-moz-transform': 'rotate(' + angle + 'deg)',
'-o-transform': 'rotate(' + angle + 'deg)',
'-ms-transform': 'rotate(' + angle + 'deg)'
});
angle+=-22.5;
});
});
Any help is much appreciated!
Try moving the angle += ... lines before the $('.drag').css(...) lines.
Cleaned up a little, and starting at angle = 0:
// rotator
var angle = 0;
function rotateTo(angle) {
var value = 'rotate(' + angle + 'deg)';
$('.drag').css({
'-webkit-transform': value,
'-moz-transform': value,
'-o-transform': value,
'-ms-transform': value,
});
}
$('#spin').click(function() {
angle += 22.5;
rotateTo(angle);
});
$('#spin2').click(function() {
angle -= 22.5;
rotateTo(angle);
});

To display Image I used colorbox..In that I have add rotate-left and rotate-right to rotate the image..
The code is:
var rotate_right = document.getElementById('cboxRight');
$(rotate_right).on('click', function () {
var cboxphoto = document.getElementsByClassName('cboxPhoto')[0].style;
cboxphoto.setAttribute('-ms-transform', 'rotate(90deg)');
});
var rotate_left = document.getElementById('cboxLeft');
$(rotate_left).on('click', function () {
var cboxphoto = document.getElementsByClassName('cboxPhoto')[0].style;
cboxphoto.setAttribute('-ms-transform', 'rotate(270deg)');
});
It rotate 90deg if I click again on rightrotate button then it wont work..I want to rotate it again when click on button
You're only ever rotating to 90 or 270 degrees. When you click again, it doesn't move as it is already rotated to that angle.
Keep track of the current rotation instead and set the attribute to that value plus or minus 90deg - you can probably clean up the code a bit as well, but something like this fiddle: http://jsfiddle.net/w6ho689e/
var degrees = 0;
$("#cboxRight").on('click', function () {
var $cboxphoto = $('.cboxPhoto');
degrees += 90;
$cboxphoto.css('-ms-transform', 'rotate(' + degrees + 'deg)');
$cboxphoto.css('-webkit-transform', 'rotate(' + degrees + 'deg)');
$cboxphoto.css('transform', 'rotate(' + degrees + 'deg)');
});
$("#cboxLeft").on('click', function () {
var $cboxphoto = $('.cboxPhoto');
degrees -= 90;
$cboxphoto.css('-ms-transform', 'rotate(' + degrees + 'deg)');
$cboxphoto.css('-webkit-transform', 'rotate(' + degrees + 'deg)');
$cboxphoto.css('transform', 'rotate(' + degrees + 'deg)');
});
How do I make the center of the div as the center point for the rotation.
I came across this while I was doing some research but I can't seem to fit it in to mine.
This is what the post has suggested. But doesn't work.
$(area).css('-webkit-transform-origin', 'rotate(' + dgR + 'deg)');
function rot(e, area) {
var offset = area.offset();
var ceX = (offset.left) + ($(area).width() /2);
var ceY = (offset.top) + ($(area).height() /2);
var muX = e.pageX;
var muY = e.pageY;
var rdi = Math.atan2(muX-ceX, muY-ceY);
var dgR = (rdi * (180/Math.PI)*-5);
$(area).css('transform', 'rotate(' + dgR + 'deg)');
$(area).css('-webkit-transform', 'rotate(' + dgR + 'deg)');
$(area).css('-o-transform', 'rotate(' + dgR + 'deg)');
$(area).css('-ms-transform', 'rotate(' + dgR+'deg)');
}
You're using the transform-origin incorrect.
$(area).css('-webkit-transform-origin', '50% 50%');
This should place the rotation origin point in the middle of the area
When I got you right, you just want to rotate a div in it's center point, aren't you? Here you have to define the center point with transform-origin: 50% 50%; in your div.
Heres a fiddle to play around (without jscript): http://jsfiddle.net/nub0umft/
How could I do clearTimeout if I have multiple settimeout?
Here I have a code:
var $elie = $(".gear"), degree = 0, timer;
function rotate() {
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
$elie.css({ 'transform': 'rotate(' + degree + 'deg)'});
timer = setTimeout(function() {
++degree; rotate();
$('.gear').attr('timeout',timer);
},25);
}
$(".google").hover(function() {
clearTimeout($('.gear').attr('timeout'));
});
$(".gear").hover(function() {
rotate();
});
That is: http://jsfiddle.net/T9YxL/1/
The problem is: I hover on the gear once, than hover on Google logo — everything stops as it has. But when I hover on the gear twice, I have to hover on Google logo twice and so on. How to clear all these settimeout at once even for example I hovered on the gear 100 times?
I looked here:
clearTimeout on multiple setTimeout
but it didn't help.
timer = setTimeout(function() {
++degree; rotate();
$('.gear').attr('timeout',timer);
},25);
should be
timer = setTimeout(function() {
++degree; rotate();
},25);
$('.gear').attr('timeout',timer);
and :
$(".gear").hover(function() {
rotate();
});
should be
$(".gear").hover(function() {
clearTimeout($('.gear').attr('timeout'));
rotate();
});

Hi guys at the moment i am trying to figure out how to rotate a div and make it stop at a loctation. I have had some help on this however iam not sure what iam doing wrong. Any help with the code would be great.
Thanks guys for the help
try change your javascript code to be like this:
$(window).load(function(){
var $elie = $("#super");
rotate(1);
function rotate(degree) {
$elie.css({
'-webkit-transform': 'rotate(' + degree + 'deg)',
'-moz-transform': 'rotate(' + degree + 'deg)',
'-o-transform': 'rotate(' + degree + 'deg)',
'-ms-transform': 'rotate(' + degree + 'deg)',
'transform': 'rotate(' + degree + 'deg)'
});
console.log(degree);
if (degree < 100) {
timer = setTimeout(function() {
rotate(++degree)
}, 1);
}}
});
Here the demo: http://jsfiddle.net/ongisnade/mq8Ar/
Look at here http://jsbin.com/uwunaw/4/edit
I'm adding var elie = null; as global var and put elie = $("#super"); in onReady of jQuery.
Like this
$(function () {
elie = $("#super");
rotate(1);
});
It's working now.
My goal with this code is to create an effect of leaves blowing away 3 seconds after page load, but currently I am unable to create a delay. Perhaps its because the code format. I made i quick jsfiddle to demonstrate what I have so far.
http://jsfiddle.net/vXpDk/
So my question is how to create a delay of the function so that it doesn't start to rotate and slide for 3 seconds...and if it is possible to to create diagonal paths instead of horizontal and vertical.
Here's the code from the jsFiddle:
var $elie = $("#leaf1"), degree = 0, timer;
rotate();
function rotate() {
$elie.delay(2000)
.css({ WebkitTransform: 'rotate(' + degree + 'deg)'})
.animate({ "left": "+=800px" }, 2000)
.fadeOut(100);
$elie.delay(2000)
.css({ '-moz-transform': 'rotate(' + degree + 'deg)'})
.animate({ "left": "+=800px" }, 2000)
.fadeOut(100);
timer = setTimeout(function() {
++degree;
rotate();
},0);
}
Like this? http://jsfiddle.net/L69Ud/
var $elie = $("#leaf1"), degree = 0;
$elie.animate({ "left": "+=800px" }, 5000).fadeOut(100);
setTimeout(rotate, 3000);
function rotate() {
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
setTimeout(function() {
++degree; rotate();
}, 0);
}
and if it is possible to to create diagonal paths instead of
horizontal and vertical.
Animate left and top at the same time http://jsfiddle.net/L69Ud/1/
The only modification here is
$elie.animate({ left: "+=500px", top: "+=500px" }, 5000).fadeOut(100);
How would you code this so that the div does not move at all for 3 seconds then begins to rotate and slide at the same time?
http://jsfiddle.net/L69Ud/3/
var $elie = $("#leaf1"), degree = 0;
setTimeout(function() {
$elie.animate({ left: "+=500px", top: "+=500px" }, 5000).fadeOut(100);
rotate();
}, 3000);
function rotate() {
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
setTimeout(function() {
++degree; rotate();
}, 0);
}
