# 笔记
作用:在插入、更新或移除 DOM 元素时,在合适的时候给元素添加样式类名。
写法:
准备好样式:
- 元素进入的样式:
v-enter:
进入的起点v-enter-active:
进入过程中v-enter-to:
进入的终点
- 元素离开的样式:
v-leave:
离开的起点v-leave-active:
离开过程中v-leave-to:
离开的终点
- 元素进入的样式:
使用
<transition>
包裹要过度的元素,并配置 name 属性:<transition name="hello"> <h1 v-show="isShow">你好啊!</h1> </transition>
1
2
3备注:若有多个元素需要过度,则需要使用:
<transition-group>
,且每个元素都要指定key
值。
