How to modify TimelineLite timing? - javascript

I’m quite new with the GreenSock and I got myself in trouble...
I would like to modify GreenSock TimelineLite timing offset for reverse so that some delays get deleted (I think that they are called staggers).
Here is an example: http://jsfiddle.net/4bvnv1d5/
var red = $('.red');
var green = $('.green');
var blue = $('.blue');
var black = $('.black');
var tl = new TimelineLite({onReverseComplete:reverseCompleted});
$('#start').click(function(){
tl.to(red, 0.3, {ease: Power1.easeInOut, 'margin-left':'100px'});
tl.to(green, 0.3, {ease: Power1.easeInOut, 'margin-left':'100px'});
tl.to(blue, 0.3, {ease: Power1.easeInOut, 'margin-left':'100px'});
tl.to(black, 0.3, {ease: Power1.easeInOut, 'margin-left':'100px', onComplete:lastCompleted, onCompleteParams:[black]}, "+=4");
});
$('#reverse').click(function(){
tl.reverse();
});
function lastCompleted(target) {
console.log('lastCompleted');
}
function reverseCompleted(){
console.log('reverseCompleted');
tl.clear();
tl.restart();
}
On play there is a four second delay with the last box, but on the reverse I’d like to animations to play right after each other with no delays. There is function lastCompleted() which is triggered after the last tween gets run. How can I use that function to remove the delay between the black and blue box animations?
Thanks!

Take a look at this fiddle.
JavaScript:
var red = $('.red');
var green = $('.green');
var blue = $('.blue');
var black = $('.black');
var tl = new TimelineLite({
paused: true,
callbackScope: this,
onReverseComplete: onTlReverseComplete
});
tl.staggerTo([red, green, blue], 0.3, { marginLeft: 100, ease: Power1.easeInOut }, 0.3);
tl.addLabel('MyLabel');
tl.to(black, 0.3, { marginLeft: 100, ease: Power1.easeInOut, onReverseComplete: onBlackBoxReverseComplete, callbackScope: this }, '+=4');
$('#start').click(function () {
tl.play();
});
$('#reverse').click(function () {
tl.reverse();
});
function onBlackBoxReverseComplete() {
tl.reverse('MyLabel');
}
function onTlReverseComplete() {
tl.stop();
}
Quite a few things have changed from your code. Here is the list:
The tweens are added into the tl instance outside the scope of click handler of #start button. The click handler only .play()s the timeline forward.
.staggerTo() method is used instead of adding adding the 3 tweens one by one before the one for .black element.
Also, margin-left has been replaced by its JS equivalent marginLeft and since it accepts numbers and defaults to pixels, no need to pass the values as strings.
The tween for .black element has now a onReverseComplete callback.
Hope this helps. Let me know if you have any questions.

TweenMax after animation finished

When first animation will be done after that I want another animation on the same target.
var lnk = document.querySelector('#clickme');
var tl = new TimelineMax();
lnk.addEventListener('click', go, false);
function go(){
tl.to('.glasko', 1, {width: 500, height: 500});
};
After that I want to change background color of div.
tl.to('.glasko', 2, {backgroundColor: 'red'});
What is best practice for this?
GSAP makes it easy & simple with TimelineMax. You just need to write second animation after first animation using same TimelineMax instance and this is the best approach.
var lnk = document.querySelector('#clickme');
var tl = new TimelineMax();
lnk.addEventListener('click', go, false);
function go(){
tl.to('.glasko', 1, {width: 500, height: 500});
tl.to('.glasko', 2, {backgroundColor: 'red'});
};

Retain one tween out of many in one function (TweenMax JS)

Im working on a site that requires the "3D card flip effect." I'm already using TweenMax to animate certain graphics on the site so I figured I would use TweenMax for the 3D card flip.
I have this. Basically it scales up and rotates on the hover state. I want it to scale up, rotate and scale down while retaining the rotationY property. Any ideas how to do this?
$('#selector').on('mouseover', cardFlip).on('mouseout', cardFlipBack);
function cardFlip(e) {
var tar = $(e.currentTarget);
$(e.currentTarget).css("z-index", "210");
TweenMax.to(tar, 0.25, {css: {scale: 1.5, rotationY: -180}});
}
function cardFlipBack(e) {
var tar = $(e.currentTarget);
TweenMax.to(tar, 0.25, {css: {scale: 1, rotationY: 0}});
}
I got it working! When you hover over the image it scales down and up when you 'mouseout.' When you click on the object the card scales up, flips 180 degrees and stays there until you click it again, then it reverts back to its original degree and scale.
var cardFlipClick = false;
$('#include-why').on('mouseover', hoverin).on('mouseout', hoverout).on('click', cardFlip);
function cardFlip(e) { // MAKES CARD FLIP WORK
if('click') {
if (!cardFlipClick) {
console.log('flipCard1 CLICKED!');
var card = $(e.currentTarget).off('mouseout').off('mouseover').css("z-index", "210");
TweenMax.to(card, 0.4, {css: {rotationY: -180, scale: 1.5}});
cardFlipClick = true;
} else if (cardFlipClick) {
var card = $(e.currentTarget).on('mouseout', hoverout).on('mouseover', hoverin);
console.log('flipCard2 CLICKED!');
TweenMax.to(card, 0.4, {css: {rotationY: 0, scale: 1}});
cardFlipClick = false;
}
}
}

How to prevent loss hover in Raphael?

I'm developing some page when I use Raphael liblary to draw some items.
my App
So my problem is in that when I'm moving to some rect it growing up but when my mouse is on text which is positioning on my rect, it loss his hover. You can see it on my app example.
var paper = new Raphael(document.getElementById('holder'), 500, object.length * 100);
drawLine(paper, aType.length, bType.length, cType.length, cellSize, padding);
process = function(i,label)
{
txt = paper.text(390,((i+1)* cellSize) - 10,label.devRepo)
.attr({ stroke: "none", opacity: 0, "font-size": 20});
var a = paper.rect(200, ((i+1)* cellSize) - 25, rectWidth, rectHeight)
.hover(function()
{
this.animate({ transform : "s2"}, 1000, "elastic");
this.prev.animate({opacity: 1}, 500, "elastic");
this.next.attr({"font-size" : 30});
},
function()
{
this.animate({ transform : "s1" }, 1000, "elastic");
this.prev.animate({opacity: 0}, 500);
this.next.attr({"font-size" : 15});
});
}
I have tried e.preventDefault(); on hover of this.next and some other solutions but it's doesn't work.
Any help would be appreciated.
Most people will suggest you place a transparent rectangle over the box and the labels and attach the hover functions to that instead. (If memory serves, you have to make the opacity 0.01 instead of 0 to prevent the object from losing its attached events.) This works fine, but I don't love this solution; it feels hacky and clutters the page with unnecessary objects.
Instead, I recommend this: Remove the second function from the hover, making it functionally a mouseover function only. Before you draw any of the rectangles and labels, make a rectangular "mat" the size of the paper. Then, attach the function that minimizes the label as a mouseover on the mat. In other words, you're changing the trigger from mousing out of the box to mousing over the area outside of it.
I left a tiny bit of opacity and color on the mat to be sure it's working. You can just change the color to your background color.
var mat = paper.rect(0, 0, paper.width, paper.height).attr({fill: "#F00", opacity: 0.1});
Now, you want to make a container for all the rectangles so you can loop through them to see which need to be minimized. I made an object called "rectangles" that contains the objects we're concerned with. Then:
mat.mouseover(function () {
for (var c = 0; c < rectangles.length; c += 1) {
//some measure to tell if rectangle is presently expanded
if (rectangles[c].next.attr("font-size")) {
rectangles[c].animate({
transform : "s1"
}, 1000, "elastic");
rectangles[c].prev.animate({opacity: 0}, 500);
rectangles[c].next.attr({"font-size" : 15});
}
}
});
Then I just removed the mouseout function from the individual rectangles.
jsBin
To be clear, this will have some downsides: If people run the mouse around really fast, they can expand several rectangles at the same time. This is remedied as soon as the mouse touches the mat. I think the functionality looks pretty nice. But the invisible mats is always an option.
I wrote a small extension to Raphael - called hoverInBounds - that resolves this limitation.
Demo: http://jsfiddle.net/amustill/Bh276/1
Raphael.el.hoverInBounds = function(inFunc, outFunc) {
var inBounds = false;
// Mouseover function. Only execute if `inBounds` is false.
this.mouseover(function() {
if (!inBounds) {
inBounds = true;
inFunc.call(this);
}
});
// Mouseout function
this.mouseout(function(e) {
var x = e.offsetX || e.clientX,
y = e.offsetY || e.clientY;
// Return `false` if we're still inside the element's bounds
if (this.isPointInside(x, y)) return false;
inBounds = false;
outFunc.call(this);
});
return this;
}

javascript raphael object function passing

I apologize for asking this question but I am just looking for a little guidance on this morning. I simply want to create a function so that way I can make a Raphael element glow by just passing in that element. Below is the code I have. Why does this not work?
var paper = Raphael("playarea", 500, 500);
var rectangle = paper.rect(100, 100, 200, 200, 4);
function elemHover(var el)
{
el.hover(
// When the mouse comes over the object //
// Stock the created "glow" object in myCircle.g
function() {
this.g = this.glow({
color: "#0000EE",
width: 10,
opacity: 0.8
});
},
// When the mouse goes away //
// this.g was already created. Destroy it!
function() {
this.g.remove();
});
}
elemHover(rectangle);
here is the fiddle http://jsfiddle.net/aZG6C/15/
You should fill the element( rectangle in our case) to trigger the hover.
rectangle.attr("fill", "red");
Try this fiddle http://jsfiddle.net/aZG6C/17/
The full code will look like
<div id="playarea"></div>
​<script type="text/javascript">
var paper = Raphael("playarea", 500, 500);
var rectangle = paper.rect(100, 100, 200, 200, 4);
function elemHover(el)
{
el.hover(
// When the mouse comes over the object //
// Stock the created "glow" object in myCircle.g
function() {
this.g = this.glow({
color: "#0000EE",
width: 10,
opacity: 0.8
});
},
// When the mouse goes away //
// this.g was already created. Destroy it!
function() {
this.g.remove();
});
}
rectangle.attr("fill", "red");
elemHover(rectangle);
</script>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
Update
Hover event is triggered only if the element is filled with something. If you want to have a transparent element you can try
rectangle.attr("fill", "transparent");

Stop animation and reset position of an element in Raphaël.js

I have this simple animation that moves from side to side, Im trying to create a reset button so that the animation stops and gets back to default, but I cant seem to get i right.
The library I am using is Raphael, but I'm almost sure that with a simple javascript I can reset the values inside the function.
Body onload init function
function init() {
paper = Raphael("loadSVG");
var bg = paper.rect( 0, 0, "240px", "90px", 0 );
bg.attr( {fill: "#f3f3ff"} );
rect1 = paper.rect(150, 20, 50, 50);
rect1.attr( {fill: "#ffaaaa", "stroke-width": 3} );
}
The animation function
function moveRect1() {
if( xEnd == 150 )
xEnd = 50;
else
xEnd = 150;
rect1.animate( {x: xEnd}, 1000, "Sine", function (){
moveRect1();
});
}
and the stop button that don't work :)
function stopsvgRect1() {
rect1.stop();
}
You need to bind the stop button to the function you've created.
For example like this:
document.querySelector('#stop').onclick = function() {
stopsvgRect1();
};
Open this fiddle to see it in action.
edit:
As the position should also be resetted, you can choose Raphael.transform() for this action.
Open my updated fiddle to see how it works.
