</html>(像上面这种加了style并不会实现渐变效果，因为vue默认是会尽量复用dom，想要vue不复用dom，要给其加上不同的key值)
加上不同key值后，渐变效果有了：
<!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">切换</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>如果想设置多个属性之间的切换效果，可以用mode（mode="in-out"：先显示要显示的再隐藏要隐藏的。mode="out-in"：和前面的相反）：
<!DOCTYPE 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">切换</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>组件动画也是可以的（不需要上面的不同值的key）：
<!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">切换</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>动态组件的实现方法：
<!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">
//通过动态组件的方式实现：
<component :is="type"></component>
</transition>
<button @click="handleClick">切换</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>
