<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href="./animate.css">
    <script src="./vue.js"></script>
    <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
    <style>
        .myfade-enter, .v-leave-to {
            opacity: 0;
        }
        .v-enter-active, .v-leave-active {
            transition: opacity 1s;
        }
    </style>
</head>
<body>
    <div id="root">
        <transition name="myfade">
            <div v-if="show">hello</div>
            <div v-else>bye</div>
        </transition>
        <button @click="handleClick">切換</button>
    </div>
    <script type="text/javascript">
        var vm = new Vue({
            el: "#root",
            data: {
                show: true
            },
            methods: {
                handleClick: function() {
                    this.show = !this.show
                }
            }
        });
    </script>
</body>
</html>

(像上面這種加了style並不會實現漸變效果，由於vue默認是會盡可能複用dom，想要vue不復用dom，要給其加上不一樣的key值)javascript

加上不一樣key值後，漸變效果有了：
css

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href="./animate.css">
    <script src="./vue.js"></script>
    <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
    <style>
        .myfade-enter, .myfade-leave-to {
            opacity: 0;
        }
        .myfade-enter-active, .myfade-leave-active {
            transition: opacity 1s;
        }
    </style>
</head>
<body>
    <div id="root">
        <transition name="myfade">
            <div v-if="show" key="hello">hello</div>
            <div v-else key="bye">bye</div>
        </transition>
        <button @click="handleClick">切換</button>
    </div>
    <script type="text/javascript">
        var vm = new Vue({
            el: "#root",
            data: {
                show: true
            },
            methods: {
                handleClick: function() {
                    this.show = !this.show
                }
            }
        });
    </script>
</body>
</html>

若是想設置多個屬性之間的切換效果，能夠用mode（mode="in-out"：先顯示要顯示的再隱藏要隱藏的。mode="out-in"：和前面的相反）：html

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href="./animate.css">
    <script src="./vue.js"></script>
    <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
    <style>
        .myfade-enter, .myfade-leave-to {
            opacity: 0;
        }
        .myfade-enter-active, .myfade-leave-active {
            transition: opacity 1s;
        }
    </style>
</head>
<body>
    <div id="root">
        <transition name="myfade" mode="out-in">
            <div v-if="show" key="hello">hello</div>
            <div v-else key="bye">bye</div>
        </transition>
        <button @click="handleClick">切換</button>
    </div>
    <script type="text/javascript">
        var vm = new Vue({
            el: "#root",
            data: {
                show: true
            },
            methods: {
                handleClick: function() {
                    this.show = !this.show
                }
            }
        });
    </script>
</body>
</html>

組件動畫也是能夠的（不須要上面的不一樣值的key）：vue

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href="./animate.css">
    <script src="./vue.js"></script>
    <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
    <style>
        .myfade-enter, .myfade-leave-to {
            opacity: 0;
        }
        .myfade-enter-active, .myfade-leave-active {
            transition: opacity 1s;
        }
    </style>
</head>
<body>
    <div id="root">
        <transition name="myfade" mode="out-in">
            <child1 v-if="show">hello</child1>
            <child2 v-else>bye</child2>
        </transition>
        <button @click="handleClick">切換</button>
    </div>
    <script type="text/javascript">
        Vue.component("child1", {
            template: "<div>child1</div>"
        });
        Vue.component("child2", {
            template: "<div>child2</div>"
        });
        var vm = new Vue({
            el: "#root",
            data: {
                show: true
            },
            methods: {
                handleClick: function() {
                    this.show = !this.show
                }
            }
        });
    </script>
</body>
</html>

動態組件的實現方法：java

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href="./animate.css">
    <script src="./vue.js"></script>
    <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> -->
    <style>
        .myfade-enter, .myfade-leave-to {
            opacity: 0;
        }
        .myfade-enter-active, .myfade-leave-active {
            transition: opacity 1s;
        }
    </style>
</head>
<body>
    <div id="root">
        <transition name="myfade" mode="out-in">
            //經過動態組件的方式實現：
            <component :is="type"></component>
        </transition>
        <button @click="handleClick">切換</button>
    </div>
    <script type="text/javascript">
        Vue.component("child1", {
            template: "<div>child1</div>"
        });
        Vue.component("child2", {
            template: "<div>child2</div>"
        });
        var vm = new Vue({
            el: "#root",
            data: {
                type: "child1"
            },
            methods: {
                handleClick: function() {
                    this.type = this.type == "child1" ? "child2" : "child1"
                }
            }
        });
    </script>
</body>
</html>
