border-radius:5px;

@keyframes myaction{

top:0px;
left:30px;
}
100%{
top:10px;
left:10px;
}
} </style>
<div id="test"> </div>
<div id="water1"></div>
<div id="water"></div> <script>
var i = 0;
$("#water").click(function () {
$(this).css("animation", "myaction 1s");
setTimeout(function () {
$("#water").removeAttr("style");
}, 1000);
});
</script>
</body>
</html>

这里测试了 CSS3中的新的特性animation,实现了一个简单的移动动画,可以通过这种方式,做出不同的效果,这里只是抛砖引玉。

下面是用JQUERY的esing行为实现的一个,效果更好。

<!DOCTYPE html>
<html>
<head>
<script src="jquery-1.11.3.min.js"></script>
<script src="jquery.easing.1.3.js"></script>
</head>
<style>
#lanzi{
width:30px;
height:30px;
background:blue;
}
#qiu{
width:20px;
height:20px;
border-radius:20px;
position:absolute;
top:500px;
left:700px;
background:red;
}
</style>
<body>
<div id="lanzi"></div>
<div id="qiu"></div>
<script>
$(function () {
$("#qiu").click(function () {
$("#qiu").animate({
top: [0, 'linear'],
left: [10, 'easeInExpo']
}, 1000).animate({
top:10,left:10
},100);
});
});
</script>
</body>
</html>

jQuery默认动画

支持toggle()、slideUp()、slideDown()、show()、hide()等jQuery内置的动画效果,使用代码如下:

$(element).slideUp({ 
    duration: 1000,  
    easing: method,  
    complete: callback 
}); 

参数duration:定义动画运动时间,毫秒,其实就是速度,时间越短,运动速度越快。

参数easing:指定动画效果,Easing js提供多种动画效果,有匀速运动、变加速运动、缓冲波动效果,它们 是:
linear,swing,jswing,easeInQuad,easeOutQuad,easeInOutQuad,easeInCubic, easeOutCubic,easeInOutCubic,
easeInQuart,easeOutQuart,easeInOutQuart, easeInQuint,easeOutQuint,easeInOutQuint,easeInSine,easeOutSine,
