關于appear的用法和enter的用法相似，它只是在第一次渲染的時候才會起作用。看完整的代碼：

別忘了引用vue.js

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>初始渲染的過渡</title> <script src="vue.js"></script></head><style> .custom-appear-active{  color: #2fe26d;  background: #b6b6b6;  transition: all 1s ease; } .custom-appear{  font-size: 40px;  color: #e069e2;  background: #7798e2; } .custom-appear-to{  color: #e29138;  background: #1c8942; }</style><body><div id="app"> <transition   appear   appear-class="custom-appear"   appear-to-class="custom-appear-to"   appear-active-class="custom-appear-active" >  <p>appear</p> </transition></div><script> new Vue({  el: "#app" })</script></body></html>

但是這里有一些問題：關于appear-class、 appear-to-class、 appear-active-class的相同屬性那個起作用的問題。

四種情況：（與他們在style中的排列順序有關系）

1、appear-class、 appear-to-class、 appear-active-class或者 appear-to-class、appear-class、 appear-active-class的排列順序，此時只有appear-active-class的屬性起作用。

2、appear-active-class、appear-class、 appear-to-class

此時appear-active-class的不起作用，由appear-class過渡到appear-to-class屬性。

3、appear-class、appear-active-class、 appear-to-class

此時appear-class屬性不起作用，由appear-active-class過渡到 appear-to-class屬性。

4、 appear-to-class、 appear-active-class、appear-class

此時appear-to-class不起作用，由appear-class過渡到 appear-active-class屬性。

enter也有相似的問題
