相对于vue1.0来说，vue2.0的动画变化还是挺大的，在1.0中，直接在元素中加 transition ，后面跟上名字。而在vue2.0中，需要把设置动画的元素、路由放在<transition name="fade"></transition>标签中，name就是动画名称。
在1.0时，css需要设置（动画名称以fade为例）.fade-transition .fade-enter .fade-leave
vue1.0动画
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>vue1.0动画</title>
<script type="text/javascript" src="js/vue.js"></script>
<style>
.oDiv {
width: 200px;
height: 200px;
border: 3px dashed red;
background: coral;
}
.fade-transition {
transition: 2s all ease;
}
.fade-enter {
opacity: 0;
}
.fade-leave {
opacity: 0;
transform: translate(200px);
}
</style>
</head>
<body>
<div id="box">
<input type="button" value="button" @click="toggle()"/>
<div class="oDiv" v-show="Dist" transition="fade">{{Dist}}</div>
</div>
</body>
<script type="text/javascript">
new Vue({
el: '#box',
data: {
Dist: false
},
methods: {
toggle: function () {
this.Dist = !this.Dist;
}
}
})
</script>
</html>
在2.0时，css设置大改，.fade-enter{}元素初始状态 .fade-enter-active{}元素最终状态 .fade-leave-active{} 元素离开的最终状态

</transition>
</div>
</body>
<script type="text/javascript">
new Vue({
el: '#box',
data: {
show: false
}
})
</script>
</html>
在2.0中，依然可以与animate.css结合起来一起写动画
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<link rel="stylesheet" type="text/css" href="css/animate.min.css"/>
<title>配合animate.css做动画</title>
<script type="text/javascript" src="js/vue.js"></script>
<style>
p{
width: 300px;
height: 300px;
background-color: yellow;
margin: 0 auto;
}
</style>
</head>
<body>
<div id="box">
<input type="button" value="点击显示隐藏" @click="show=!show">
<transition enter-active-class="zoomOutDown" leave-active-class="zoomOutUp">
<p v-show="show" class="animated"></p>
</transition>
</div>
</body>
<script type="text/javascript">
new Vue({
el: '#box',
data: {
show: false
}
})
</script>
</html>
在2.0中，关于动画还为我们提供了一些事件
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>动画事件</title>
<script type="text/javascript" src="js/vue.js"></script>
<style>
p{
width: 300px;
height: 300px;
background-color: yellow;
}
.donghua-enter-active,
.donghua-leave-active{
transition: 5s all ease;
}
.donghua-enter-active{
opacity: 1;
width: 300px;
height: 300px;
}
.donghua-leave-active{
opacity: 0;
width: 100px;
height: 100px;
}
.donghua-enter,.donghua-leave{
opacity: 0;
width: 100px;
height: 100px;
}
</style>
</head>
<body>
<div id="box">
<input type="button" value="点击显示隐藏" @click="show=!show">
<transition name="donghua"
@before-enter="beforeEnter"
@enter="Enter"
@after-enter="afterEnter"
@before-leave="beforeLeave"
@leave="Leave"
@after-leave="afterLeave"
>
<p v-show="show"></p>
</transition>
</div>
</body>
<script type="text/javascript">
new Vue({
el: '#box',
data: {
show: false
},
methods: {
beforeEnter() {
console.log("<!-- 进入动画开始之前 -->");
},
Enter() {
console.log("<!-- 正式进入动画 -->");
},
afterEnter(el) {
console.log("<!-- 动画结束 -->");
},
beforeLeave(el) {
console.log("<!-- 离开动画开始之前 -->");
el.style.background='blue'; //改变颜色
el.innerHTML="123";
},
Leave(){
console.log("<!-- 正在离开动画-->");
},
afterLeave(){
console.log("<!-- 离开动画结束 -->");
},
}
})
</script>
