代码演示

基础用法

将元素包裹在 transition 组件内，在元素展示/隐藏时，会有相应的过渡动画。

<hd-button type="primary" @click="open">fade</hd-button>
<hd-transition :show="show" custom-class="block">你好</hd-transition>

<script lang="ts" setup>

const show = ref<boolean>(false) // 是否展示

function open() {
  show.value = true
  setTimeout(() => {
    show.value = false
  }, 500)
}
</script>

过渡动画类型

transition 组件内置了多种动画，可以通过name字段指定过渡动画类型。

<button type="primary" @click="open">过渡动画</button>
<hd-transition :show="show" :name="name"></hd-transition>

<script lang="ts" setup>

const show = ref<boolean>(false) // 是否展示
const name = ref<string>('fade') // 动画类型

function open() {
  show.value = true
  setTimeout(() => {
    show.value = false
  }, 500)
}
</script>

动画类型

名称	说明
fade	淡入
fade-up	上滑淡入
fade-down	下滑淡入
fade-left	左滑淡入
fade-right	右滑淡入
slide-up	上滑进入
slide-down	下滑进入
slide-left	左滑进入
slide-right	右滑进入
zoom-in	由小到大
zoom-out	由大到小

过渡动画持续时间

通过duration设置过渡动画持续时间，单位毫秒，默认动画持续时间为 300 毫秒。

<hd-button type="primary" @click="open">过渡动画</hd-button>
<hd-transition :show="show" :duration="duration"></hd-transition>

<script lang="ts" setup>

const show = ref<boolean>(false) // 是否展示
const duration = ref<Record<string,number>>({ enter: 300, leave: 1000 }) 
 // 动画类型

function open() {
  show.value = !show.value
}
</script>

自定义样式和自定义类名

组件可以通过custom-style属性设置自定义样式；也可以通过custom-class属性设置自定义类名。

<button type="primary" @click="open">过渡动画</button>
<hd-transition :show="show" :custom-style="styles" custom-class="custom-class"></hd-transition>

<script lang="ts" setup>

const show = ref<boolean>(false) // 是否展示
const styles = ref<string>('position: fixed; bottom: 0;top: 0;left: 0;right: 0;backgroundColor: rgba(0, 0, 0, 0.4);') // 自定义样式
 // 动画类型

function open() {
  show.value = !show.value
}
</script>

高级用法

可以通过外部样式类自定义过渡效果。

<hd-button type="primary" @click="open">过渡动画</hd-button>
<hd-transition
  :show="show"
  name=" "
  :duration="{ enter: 300, leave: 1000 }"
  custom-class="custom-class"
  enter-class="custom-enter-class"
  enter-active-class="custom-enter-active-class"
  leave-active-class="custom-leave-active-class"
  leave-to-class="custom-leave-to-class"
  @before-enter="onBeforeEnter"
  @enter="onEnter"
  @after-enter="onAfterEnter"
  @before-leave="onBeforeLeave"
  @leave="onLeave"
  @after-leave="onAfterLeave"
/>

<script lang="ts" setup>

const show = ref<boolean>(false) // 是否展示
 // 动画类型

function open() {
    this.show = !this.show
}
function onBeforeEnter() {
  console.log('before enter')
}
function onEnter() {
  console.log('enter')
}
function onAfterEnter() {
  console.log('after enter')
}
function onBeforeLeave() {
  console.log('before leave')
}
function onLeave() {
  console.log('leave')
}
function onAfterLeave() {
  console.log('after leave')
}
</script>
