做动画-3d-WebGL常用的js库

2018-07-15 分类：JavaScript 作者：管理员阅读（602）

前言:我所熟知的关于做动画3d可视化的几个js库,如下:
1.jQuery的animate() animate
2.TweenMax.js TweenMax
3.three.js three
4.d3.js d3
5.echarts.js echarts
6.highcharts highcharts

以下都是简单的例子更多案例请移步官网查看

jquery-animate(动画)

<!DOCTYPE html>

position: absolute;
}
</style>
<body>
<div id="box"></div>
</body>
<script>

/*
$(selector).animate({params},speed,callback);
必需的 params 参数定义形成动画的 CSS 属性。
可选的 speed 参数规定效果的时长。它可以取以下值："slow"、"fast" 或毫秒。
可选的 callback 参数是动画完成后所执行的函数名称
*/
$('#box').animate({
left:'250px',
opacity:'0.5',
height:'250px',
width:'250px'
},2000,function(){
$(this).animate({
left:'500px',
opacity:'1',
height:'150px',
width:'150px'
},1000,function(){
alert('动画结束')
})
})
// 使用相对值也可以定义相对值（该值相对于元素的当前值）。需要在值的前面加上 += 或 -=：
// 使用预定义的值您甚至可以把属性的动画值设置为 "show"、"hide" 或 "toggle"
</script>

TweenMax.js(动画)

<div id="box"></div>
<button id="play">play</button>
<button id="stop">stop</button>

<script>

//得到实例
var t=new TimelineMax();

//开始使用实例下面的方法
t.to('#box',1,{left:200},1)
t.to('#box',1,{top:'+=200',onComplete:function(){alert('继续动画就点我')}},'+=1')
t.to('#box',1,{left:'+=200'},'+=1')
t.to('#box',1,{top:'+=200'},'+=1')
t.to('#box',1,{left:'-=200'},'+=1')
t.to('#box',1,{top:'-=200'},'+=1')
t.to('#box',1,{left:'-=200'},'+=1')
t.to('#box',1,{top:'-=200',onComplete:function(){
//运动结束后触发对应的函数
alert('动画结束了')
}},'+=1')

document.getElementById('play').onclick=function(){
t.play()
}
document.getElementById('stop').onclick=function(){
t.stop()
}
/*

to()：添加动画
参数说明：
1. 元素（原生，jq），元素选择器或对象
2. 持续时间（s）
3. 对象 :变化的属性->值
4. 【可选】动画延迟发生时间 (可写数字，“-=0.5”，“+=0.5“)

其他方法
stop()：停止动画
play()：开始动画
reverse()：反向开始动画
onComplete()：运动结束后触发对应的函数
onReverseComplete()：反向运动结束后触发对应的函数
