1.css动画原理

        .fade-enter{
            opacity: 0;
        }
        .fade-enter-active{
            transition: opacity 2s;
        }

.fade-leave-to{
    opacity: 0;
}
.fade-leave-active{
    transition: opacity 2s;
}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>vue中css动画原理</title>
    <script src="../../vue.js"></script>
    <style>
        .fade-enter{
            opacity: 0;
        }
        .fade-enter-active{
            transition: opacity 2s;
        }
        .fade-leave-to{
            opacity: 0;
        }
        .fade-leave-active{
            transition: opacity 2s;
        }
    </style>
</head>
<body>
<div id="app">
    <transition name="fade">
        <div v-if="show">hello world</div>
    </transition>
    <button @click="handleCLick">click me</button>
</div>
<script>
    var vm = new Vue({
        el:"#app",
        data:{
            show:true,
        },
        methods:{
            handleCLick:function () {
                this.show = !this.show
            }
        }
    })
</script>
</body>

2.使用animate.css库

animate.css 提供了大量的动画效果,官网:https://daneden.github.io/animate.css/?

使用animate.css   需要在transition 标签中自定义 属性名字,例如:

enter-active-class="animated hinge"
leave-active-class="animated jello"
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>使用animate-css库</title>
    <script src="../../vue.js"></script>
    <link rel="stylesheet" href="../../animate.css">
</head>
<body>
<div id="app">
    <!--使用animate-css 自定义名字  animated开头-->
    <transition enter-active-class="animated hinge"
                leave-active-class="animated jello">
        <div v-if="show">hello world</div>
    </transition>
    <button @click="handleCLick">click me</button>
</div>
<script>
    var vm = new Vue({
        el:"#app",
        data:{
            show:true,
        },
        methods:{
            handleCLick:function () {
                this.show = !this.show
            }
        }
    })
</script>
</body>
</html>
View Code

在第一次进入页面时,附带效果

在transition 中添加属性:

appear
appear-active-class="animated hinge"

3. 同时使用过渡和动画

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>同时使用过渡和动画</title>
    <script src="../../vue.js"></script>
    <link rel="stylesheet" href="../../animate.css">
    <style>
        .fade-enter,.fade-leave-to{
            opacity: 0;
        }
        .fade-leave-active,
        .fade-enter-active{
            transition: opacity 3s;
        }

    </style>
</head>
<body>
<div id="app">
    <!--:duration 自定义时长,-->
    <!--例如:设置出场入场动画时间-->
    <!--:duration=“{enter:5000,leave:10000}”-->

    <!--appear  appear-active-class:初次动画-->

    <!--type 确定哪种为时长为准-->

    <transition enter-active-class="animated hinge fade-enter-active"
                leave-active-class="animated jello fade-leave-active"
                appear
                name="fade"
                type="transition"
                appear-active-class="animated hinge">
        <div v-if="show">hello world</div>
    </transition>
    <button @click="handleCLick">click me</button>
</div>
<script>
    var vm = new Vue({
        el:"#app",
        data:{
            show:true,
        },
        methods:{
            handleCLick:function () {
                this.show = !this.show
            }
        }
    })
</script>
</body>

4.js动画与Velocity-js结合

<!--动画钩子-->
<!--显示:-->
<!--before-enter(el)-->
<!--enter(el,done)  done为回调函数-->
<!--after-enter-->

<!--隐藏:-->
<!--before-leave-->
<!--after-leave-->
<!--leave-->

绑定事件:

    <transition name="fade"
    @before-enter="handleBeforEnter"
    @enter="handleEnter"
    @after-enter="handleafterEnter"
                @leave="handleLeave"
    >
        <div v-show="show">hello world</div>
    </transition>

处理事件:

            handleCLick:function () {
                this.show = !this.show
            },
            handleBeforEnter:function (el) {
                el.style.color = 'red'
            },
            handleEnter:function (el,done) {
                setTimeout(()=>{
                    // 执行结束后,执行done
                    el.style.color = 'yellow'
                },2000)
                setTimeout(()=>{
                    done()
                },4000)
            },
            handleafterEnter:function (el) {
                el.style.color = 'black'
            }
