尝试构建手风琴菜单。菜单下项目的动画是平滑的,但是菜单的关闭和打开都不平滑。
我发现了几个类似https://codepen.io/anon/pen/dgBWjy?editors=0100的示例。但还不能解决我的问题
到目前为止,这是我的代码。关于如何解决该问题的任何想法吗?
<template>
<div class="accord">
<div v-for="group in groups">
<a class="menu_grps" v-on:click="group.open = !group.open" v-text="group.name"></a>
<div id="anim">
<transition name="slide">
<div v-show="!group.open">
<div v-for="item in group.items" v-text="item"></div>
</div>
</transition>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
groups: {
"group 1": {
name: "Menu 1",
open: "false",
items: ['item1', 'item2']
},
"group 2": {
name: "Menu 2",
open: "false",
items: ['item1', 'item2', 'item3']
},
"group 3": {
name: "Menu 3",
open: "false",
items: ['item1', 'item2', 'item3', 'item4']
}
}
}
}
}
</script>
<style>
.slide-leave-active,
.slide-enter-active {
transition: all .5s ease;
}
.slide-enter,
.slide-leave-to{
opacity: 0;
transform: translateY(-100%);
margin-bottom: -10px;
}
.menu_grps{
background-color: #BFAEAB;
font-size: 18px;
}
#anim {
overflow: hidden;
}
.accord{
display: flex;
flex-direction: column;
}
</style>
答案 0 :(得分:0)
如果将下边距更改为下面的-100px,它将变得更加平滑:
.slide-enter,
.slide-leave-to{
opacity: 0;
transform: translateY(-100%);
margin-bottom: -100px;
}
