CSS Animation onClick | 易学教程

How can I get a CSS Animation to play with a JavaScript onClick? I currently have:

.classname {
  -webkit-animation-name: cssAnimation;
  -webkit-animation-duration:3s;
  -webkit-animation-iteration-count: 1;
  -webkit-animation-timing-function: ease;
  -webkit-animation-fill-mode: forwards;
}
@-webkit-keyframes cssAnimation {
  from {
    -webkit-transform: rotate(0deg) scale(1) skew(0deg) translate(100px);
  }
  to {
    -webkit-transform: rotate(0deg) scale(2) skew(0deg) translate(100px);
  }
}

How can I apply an onClick?

Are you sure you only display your page on webkit? Here is the code,passed on safari. The image (id='img') will rotate after button click.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<style type="text/css">
.classname {
  -webkit-animation-name: cssAnimation;
  -webkit-animation-duration:3s;
  -webkit-animation-iteration-count: 1;
  -webkit-animation-timing-function: ease;
  -webkit-animation-fill-mode: forwards;
}
@-webkit-keyframes cssAnimation {
  from {
    -webkit-transform: rotate(0deg) scale(1) skew(0deg) translate(100px);
  }
  to {
    -webkit-transform: rotate(0deg) scale(2) skew(0deg) translate(100px);
  }
}
</style>
<script type="text/javascript">
  function ani(){
    document.getElementById('img').className ='classname';
  }
</script>
<title>Untitled Document</title>
</head>

<body>
<input name="" type="button" onclick="ani()" />
<img id="img" src="clogo.png" width="328" height="328" />
</body>
</html>

You can achieve this by binding an onclick listener and then adding the animate class like this:

$('#button').onClick(function(){
    $('#target_element').addClass('animate_class_name');
});

You just use the :active pseudo-class. This is set when you click on any element.

.classname:active {
    /* animation css */
}

NoteTheNote

Add a

-webkit-animation-play-state: paused;

to your CSS file, then you can control whether the animation is running or not by using this JS line:

document.getElementById("myDIV").style.WebkitAnimationPlayState = "running";

if you want the animation to run once, every time you click. Remember to set

-webkit-animation-iteration-count: 1;

You can do that by using following code

$('#button_id').on('click', function(){
$('#element_want_to_target').addClass('.animation_class');});

Try this:

<div>
 <p onclick="startAnimation()">Start</p><!--O botão para iniciar (start)-->
 <div id="animation">Hello!</div> <!--O elemento que você quer animar-->
</div>

<style>
@keyframes animationName {
from {margin-left:-30%;}
}
</style>

<script>
function startAnimation() {
    document.getElementById("animation").style.animation = "animationName 2s linear 1";
}
</script>

var  abox = document.getElementsByClassName("box")[0];
function allmove(){
        abox.classList.remove("move-ltr");
        abox.classList.remove("move-ttb");
       abox.classList.toggle("move");
}
function ltr(){
        abox.classList.remove("move");
        abox.classList.remove("move-ttb");
       abox.classList.toggle("move-ltr");
}
function ttb(){
       abox.classList.remove("move-ltr");
       abox.classList.remove("move");
       abox.classList.toggle("move-ttb");
}

.box {
  width: 100px;
  height: 100px;
  background: red;
  position: relative;
}
.move{
  -webkit-animation: moveall 5s;
  animation: moveall 5s;
}
.move-ltr{
   -webkit-animation: moveltr 5s;
  animation: moveltr 5s;
}
.move-ttb{
    -webkit-animation: movettb 5s;
  animation: movettb 5s;
}
@keyframes moveall {
  0%   {left: 0px; top: 0px;}
  25%  {left: 200px; top: 0px;}
  50%  {left: 200px; top: 200px;}
  75%  {left: 0px; top: 200px;}
  100% {left: 0px; top: 0px;}
}
@keyframes moveltr {
  0%   { left: 0px; top: 0px;}
  50%  {left: 200px; top: 0px;}
  100% {left: 0px; top: 0px;}
}
@keyframes movettb {
  0%   {left: 0px; top: 0px;}
  50%  {top: 200px;left: 0px;}
  100% {left: 0px; top: 0px;}
}

<div class="box"></div>
<button onclick="allmove()">click</button>
<button onclick="ltr()">click</button>
<button onclick="ttb()">click</button>
