Vue中transition标签的基本使用教程

<template>
    <div>
        <button @click="bol = !bol">隐藏/显示</button>
        <!-- Vue 的内置动画标签 transition -->
        <transition>
            <!-- 只能包含 1 个元素 -->
            <h1 v-show="bol">组件动画效果</h1>
            <!-- 需要设置 v-show / v-if 属性控制元素的显示 -->
        </transition>
    </div>
</template>

<script>
export default {
    name: "App",
    data() {
        return { bol: true };
    },
};
</script>

<style>
/* 进入动画 */
.v-enter-active {
    animation: move 1s;
}

/* 离开动画 */
.v-leave-active {
    animation: move 1s reverse;
}

@keyframes move {
    from {
        transform: translateX(-100%);
    }
    to {
        transform: translate(0);
    }
}
</style>

<template>
    <div>
        <button @click="bol = !bol">隐藏/显示</button>
        <!-- transition 标签元素设置了 name、appear 属性 -->
        <transition name="moveCartoon" appear>
            <!-- 动画会在一开始便生效 -->
            <h1 v-show="bol">组件动画效果</h1>
