一、Vue中的CSS动画原理
transition标签
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中CSS动画原理</title>
<script src="../vue.js"></script>
<style>
.v-enter,
.v-leave-to {
opacity: 0;
}
.v-enter-active,
.v-leave-active {
transition: opacity 3s;
}
</style>
</head>
<body>
<div id="app">
<transition>
<div v-if="show">hello world</div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el:"#app",
data: {
show: true
},
methods:{
handleClick: function() {
this.show = !this.show
}
}
})
</script>
</body>
</html>
二、Vue中的JS动画与velocity.js
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中的JS动画与velocity.js</title>
<script src="../vue.js"></script>
<script src="../velocity.js"></script>
</head>
<body>
<div id="app">
<transition
name="fade"
@before-enter="handleBeforeEnter"
@enter="handleEnter"
@after-enter="handleAfterEnter"
>
<div v-if="show">hello world</div>
</transition>
<button @click="handleClick">toggle</button>
</div>
<script>
var vm = new Vue({
el:"#app",
data: {
show: true
},
methods:{
handleClick: function() {
this.show = !this.show
},
handleBeforeEnter: function(el) {
el.style.opacity = 0;
},
handleEnter: function(el, done) {
Velocity(el, {
opacity: 1,
}, {
duration: 1000,
complete: done
})
},
handleAfterEnter: function(el) {
console.log('动画结束');
}
}
})
</script>
</body>
</html>
三、Vue中多个元素或者组件的过渡
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中多个元素或者组件的过渡</title>
<script src="../vue.js"></script>
<script src="../velocity.js"></script>
<style type="text/css">
.v-enter, .v-leave-to {
opacity: 0;
}
.v-enter-active, .v-leave-active {
transition: opacity 1s;
}
</style>
</head>
<body>
<div id="app">
<transition mode="in-out">
<component :is="type"></component>
</transition>
<button @click="handleClick">toggle</button>
</div>
<script>
Vue.component('chile', {
template:"<div>child</div>"
})
Vue.component('chile-one', {
template:"<div>child-one</div>"
})
var vm = new Vue({
el:"#app",
data: {
type: 'chile'
},
methods:{
handleClick: function() {
this.type = this.type === 'chile' ? 'chile-one' : 'chile';
},
}
})
</script>
</body>
</html>
四、Vue中的列表过渡
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中的列表过渡</title>
<script src="../vue.js"></script>
<style>
.v-enter, .v-leave-to {
opacity: 0;
}
.v-enter-active, .v-leave-active {
transition: opacity 1s;
}
</style>
</head>
<body>
<div id="app">
<transition-group>
<div v-for="(item, index) of list" :key="item.id">{{item.title}}</div>
</transition-group>
<button @click="handleBtnClick">Add</button>
</div>
<script>
var count = 0;
var app = new Vue({
el:'#app',
data:{
list: []
},
methods:{
handleBtnClick: function() {
this.list.push({
id: count++,
title: 'hello world'
})
}
}
})
</script>
</body>
</html>
五、Vue中的动画封装
使用css动画：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中的动画效果</title>
<script src="../vue.js"></script>
<style>
.v-enter, .v-leave-to {
opacity: 0;
}
.v-enter-active, .v-leave-active {
transition: opacity 1s;
}
</style>
</head>
<body>
<div id="app">
<fade :show="show">
<div>Hello World</div>
</fade>
<fade :show="show">
<h1>Hello World</h1>
</fade>
<button @click="handleBtnClick">toggle</button>
</div>
<script>
Vue.component('fade', {
props:['show'],
template:`
<transition>
<slot v-if="show"></slot>
</transition>
`
})
var app = new Vue({
el:'#app',
data:{
show: false
},
methods:{
handleBtnClick: function() {
this.show = !this.show
}
}
})
</script>
</body>
</html>
使用js动画：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue中的动画效果</title>
<script src="../vue.js"></script>
</head>
<body>
<div id="app">
<fade :show="show">
<div>Hello World</div>
</fade>
<fade :show="show">
<h1>Hello World</h1>
</fade>
<button @click="handleBtnClick">toggle</button>
</div>
<script>
Vue.component('fade', {
props:['show'],
template:`
<transition
@before-enter="handleBeforeEnter"
@enter="handleEnter"
>
<slot v-if="show"></slot>
</transition>
`,
methods:{
handleBeforeEnter: function(el) {
el.style.color = 'red'
},
handleEnter: function(el, done) {
setTimeout(() => {
el.style.color = 'green'
done()
}, 2000)
}
}
})
var app = new Vue({
el:'#app',
data:{
show: false
},
methods:{
handleBtnClick: function() {
this.show = !this.show
}
}
})
</script>
</body>
</html>
