动画效果

如果在<transition name="hello"></transition>标签添加name属性，那么css属性名生效就得这样写.hello-enter-active和.hello-leave-active，没有name属性就直接.v-enter-active和.v-leave-active

src/App.vue

<template>
    <div>
        <Test/>
    </div>
</template>

<script>
import Test from './components/Test.vue'

export default {
    name: 'App',
    components: { Test }
}
</script>

src/components/Test.vue

<template>
    <div>
        <button @click="isShow = !isShow">显示/隐藏</button>
        <transition name="hello" appear>
            <h1 v-show="isShow">你好啊！</h1>
        </transition>
    </div>
</template>

<script>
export default {
    name: 'Test',
    data() {
        return{
            isShow: true
        }
    }
}
</script>
<style scoped>
h1 {
    background-color: orange;
}

.hello-enter-active {
    animation: atguigu 1s linear;
}

.hello-leave-active {
    animation: atguigu 1s linear reverse;
}

@keyframes atguigu {
    from {
        transform: translateX(-100%);
    }

    to {
        transform: translateX(0px);
    }
}
</style>

src/main.js

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

//创建vm
new Vue({
    el: '#app',
    render: h => h(App),
    beforeCreate(){
        Vue.prototype.$bus=this //安装全局事件总线
    }
})

 

过渡效果

src/components/Test2.vue

<template>
    <div>
        <button @click="isShow = !isShow">显示/隐藏</button>
        <transition name="hello" appear>
            <h1 v-show="isShow">你好啊！</h1>
        </transition>
    </div>
</template>

<script>
export default {
    name: 'Test2',
    data() {
        return{
            isShow: true
        }
    }
}
</script>
<style scoped>
h1 {
    background-color: orange;
}

/* 进入起点，离开终点 */
.hello-enter,.hello-leave-to{
    transform: translateX(-100%);
}

.hello-enter-active,.hello-leave-active{
    transition: 1s linear;
}

/* 进入终点，离开起点 */
.hello-enter-to,.hello-leave{
    transform: translateX(0);
}
</style>

src/App.vue

<template>
    <div>
        <Test/>
        <Test2/>
    </div>
</template>

<script>
import Test from './components/Test.vue'
import Test2 from './components/Test2.vue'

export default {
    name: 'App',
    components: { Test,Test2 }
}
</script>

 

<transition></transition>标签只能使用单一过渡，多个过渡必须使用<transition-group></transition-group>,而且children必须添加key属性

<template>
    <div>
        <button @click="isShow = !isShow">显示/隐藏</button>
        <transition-group name="hello" appear>
            <h1 v-show="!isShow" key="1">你好啊！</h1>
            <h1 v-show="isShow" key="2">黑马</h1>
        </transition-group>
    </div>
</template>

 

集成第三方动画

npm install animate.css

Animate.css | A cross-browser library of CSS animations.

src/components/Test3.vue 

<template>
    <div>
        <button @click="isShow = !isShow">显示/隐藏</button>
        <transition-group 
            name="animate__animated animate__bounce" 
            appear
            enter-active-class="animate__swing"
            leave-active-class="animate__backOutUp"
        >
            <h1 v-show="!isShow" key="1">你好啊！</h1>
            <h1 v-show="isShow" key="2">黑马</h1>
        </transition-group>
    </div>
</template>

<script>
import 'animate.css'
export default {
    name: 'Test3',
    data() {
        return{
            isShow: true
        }
    }
}
</script>
<style scoped>
h1 {
    background-color: orange;
}

</style>

注意点：import 'animate.css'和 enter-active-class和 leave-active-class

 

之前Todo-List添加过渡与动画在MyList.vue

(162条消息) Todo-List案例版本五_bubbleJessica的博客-CSDN博客

<template>
    <ul class="todo-main">
        <transition-group name="todo"appear>
            <MyItem
             v-for="todoObj in todos" 
             :key="todoObj.id" 
             :todo="todoObj" 
        />
        </transition-group>
        
    </ul>
</template>

<script>
import MyItem from './MyItem.vue'

export default {
    name: 'MyList',
    props:['todos'],
    components: { MyItem }
}
</script>

<style scoped>
/*main*/
.todo-main {
    margin-left: 0px;
    border: 1px solid #ddd;
    border-radius: 2px;
    padding: 0px;
}

.todo-empty {

    margin-top: 10px;
}

.todo-enter-active {
    animation: atguigu 1s linear;
}

.todo-leave-active {
    animation: atguigu 1s linear reverse;
}

@keyframes atguigu {
    from {
        transform: translateX(100%);
    }

    to {
        transform: translateX(0px);
