Vue 动画 过度效果(渐隐渐现)
作者:互联网
首先一个toggle 效果:
<div id="root">
<div v-if="show">hello world</div>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true
},
methods: {
handleClick: function(){
this.show = !this.show;
}
}
})
如下,渐现效果,其中,因为 transition 的name 为 fade ,因此样式名为 fade-enter … 若不给transition 命名,则使用 v-enter… 即可。(transition: opacity 1s; 是指监测到opacity有变化将变化时间延长到1s)
<style>
.fade-enter{
opacity: 0;
}
.fade-enter-active{
transition: opacity 1s;
}
</style>
</head>
<body>
<div id="root">
<transition name="fade">
<div v-if="show">hello world</div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true
},
methods: {
handleClick: function(){
this.show = !this.show;
}
}
})
</script>
渐隐效果
<style>
.fade-enter{
opacity: 0;
}
.fade-enter-active{
transition: opacity 3s;
}
.fade-leave-to{
opacity: 0;
}
.fade-leave-active{
transition: opacity 3s;
}
</style>
</head>
<body>
<div id="root">
<transition name="fade">
<div v-if="show">hello world</div>
</transition>
<button @click="handleClick">切换</button>
</div>
<script>
var vm = new Vue({
el: "#root",
data: {
show: true
},
methods: {
handleClick: function(){
this.show = !this.show;
}
}
})
</script>
