关于appear的用法和enter的用法相似,它只是在第一次渲染的时候才会起作用。看完整的代码:

别忘了引用vue.js

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>初始渲染的过渡</title>
 <script src="/UploadFiles/2021-04-02/vue.js">

但是这里有一些问题:关于appear-class、 appear-to-class、 appear-active-class的相同属性那个起作用的问题。

四种情况:(与他们在style中的排列顺序有关系)

1、appear-class、 appear-to-class、 appear-active-class或者 appear-to-class、appear-class、 appear-active-class的排列顺序,此时只有appear-active-class的属性起作用。

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

此时appear-active-class的不起作用,由appear-class过渡到appear-to-class属性。

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

此时appear-class属性不起作用,由appear-active-class过渡到 appear-to-class属性。

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

此时appear-to-class不起作用,由appear-class过渡到 appear-active-class属性。

enter也有相似的问题
