初始渲染的过渡

2022-06-06 09:02:48 作者：互联网

可以通过 appear attribute 设置节点在初始渲染的过渡

<transition appear>
  <!-- ... -->
</transition>

这里默认和进入/离开过渡一样，同样也可以自定义 CSS 类名。

<transition
  appear
  appear-class="custom-appear-class"
  appear-to-class="custom-appear-to-class" (2.1.8+)
  appear-active-class="custom-appear-active-class"
>
  <!-- ... -->
</transition>

<!DOCTYPE html>
<html lang="zh">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>初始渲染的过渡</title>
  <script src="./vue.js"></script>
</head>

<body>
  <div id="hzh">
    <button @click="hzhShow = !hzhShow">
      切换
    </button>
    <transition 
    appear
    appear-class="hzh-appear-class"
    appear-to-class="hzh-appear--to-class"
    appear-active-class="hzh-appear-active-class"
    >
      <p v-if="hzhShow">
        黄子涵
      </p>
    </transition>
  </div>
  <script>
    new Vue({
      el: '#hzh',
      data: { 
        hzhShow: false 
      }
    })  
  </script>
</body>

自定义 JavaScript 钩子：

<transition
  appear
  v-on:before-appear="customBeforeAppearHook"
  v-on:appear="customAppearHook"
  v-on:after-appear="customAfterAppearHook"
  v-on:appear-cancelled="customAppearCancelledHook"
>
  <!-- ... -->
</transition>

<!DOCTYPE html>
<html lang="zh">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>初始渲染的过渡</title>
  <script src="./vue.js"></script>
</head>

<body>
  <div id="hzh">
    <button @click="hzhShow = !hzhShow">
      切换
    </button>
    <transition 
    appear
    v-on:before-appear="hzhBeforeAppearHook"
    v-on:appear="hzhAppearHook"
    v-on:after-appear="hzhAfterAppearHook"
    v-on:appear-cancelled="hzhAppearCancelledHook"
    >
      <p v-if="hzhShow">
        黄子涵
      </p>
    </transition>
  </div>
  <script>
    new Vue({
      el: '#hzh',
      data: { 
        hzhShow: false 
      }
    })  
  </script>
</body>

在上面的例子中，无论是 appear attribute 还是 v-on:appear 钩子都会生成初始渲染过渡。
