我想在点击card_options_btn判断动画走到0点进行js操作要怎么改
比如为0点弹出个alert
<!DOCTYPE html>

试试动画事件~~~
例如:
<!DOCTYPE html>
<html>
<head>
<title>AnimationTest</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="../script/jquery-2.1.3.min.js"></script>
<style type="text/css">
html{background-color: #fff;font-family: Arial, sans-serif;font-size: 12px;color: #000;}
body{text-rendering: optimizeLegibility;-webkit-font-smoothing: antialiased;-webkit-text-size-adjust: 100%;width: 100%;margin: 0;padding: 0}
a {color: #000;text-decoration: none;}
#page{width: 1125px;margin: 0px auto;display: block;margin-top: 10px;height: 274px;}
#single_column{background-color: #fff;padding: 30px;padding-bottom: 50px;}
#card_options_container h1{font-family:"Avalon-Medium", Roboto, Arial, sans-serif;font-weight:normal;color:#000;font-size:2em;text-transform:uppercase;font-weight:bold;margin-bottom:20px;text-align: center;}
.register_signin_switcher {margin: 20px 0;text-align: center;}
#card_options_container .card_options_btn {display: inline-block;padding: 20px;min-width: 280px;font-size: 18px;text-transform: uppercase;margin: 10px 10px 20px;border: 2px solid #000;}
.card_options_btn:hover{color:red;border: 2px solid red !important;}
.clear_float {overflow: hidden;width: 100%;clear: both;}
.base-color {text-decoration: underline;color: #d50032;}
@keyframes autoh{
form {height:auto;}
to {height: 0;}
}
@-webkit-keyframes autoh{
form {height:auto;}
to {height: 0;}
}
.pageAnima {
-webkit-animation:autoh 2s;
animation:autoh 2s;
overflow:hidden;
}
</style>
</head>
<body>
<div id="page">
<div id="single_column">
<div id="card_options_container">
<h1>Register with vmei.com</h1>
<div class="register_signin_switcher center">
<a class="card_options_btn show_with" href="#">I have a Sephora Card</a>
<a class="card_options_btn show_without" href="#">I don't have a Sephora Card</a>
<div class="clear_float"></div>
<span>Have a Sephora.com.au account?<a class="base-color" href="/users/sign_in">Sign in here</a></span>
</div>
</div>
</div>
</div>
</body>
<script type="text/javascript">
$(function(){
$(".register_signin_switcher").on("click",".card_options_btn",function(){
$("#page").removeClass('pageAnima').addClass('pageAnima');
//$("#page").css({"-webkit-animation":"autoh 2s","animation":"autoh 2s","overflow":"hidden"});
});
$('#page').on("animationend",function(){
console.log('animationend');
$("#page").removeClass('pageAnima')
});
})
</script>
</html>你把css3 animation属性抽出写成一个css类名规则，然后点击时给页面加上类名。
至于判断动画结束，你就设个和动画一样时长的定时器，动画播放时启动，结束时就执行回调。
