问题描述
限时送ChatGPT账号..我正在使用实验性的 脚本设置 以创建学习环境.我有一个自制的导航栏，打开单个组件.
I am using the experimental script setup to create a learn enviroment. I got a selfmade navigation bar with open a single component.
我在使用
I am having trouble using the <component :is="" /> method. This method is described in the docs under component basics -> dynamic-components
在 Vue 3 Composition API 中，它按预期工作:
In the Vue 3 Composition API, it works as expected:
<template>
<NavigationBar
@switchTab="changeTab"
:activeTab="tab"
/>
<component :is="tab" />
</template>
<script>
import { ref } from 'vue'
import NavigationBar from './components/NavigationBar.vue'
import TemplateSyntax from './components/TemplateSyntax.vue'
import DataPropsAndMethods from './components/DataPropsAndMethods.vue'
export default {
components: {
NavigationBar,
TemplateSyntax,
DataPropsAndMethods
},
setup () {
const tab = ref('DataPropsAndMethods')
function changeTab (newTab) {
tab.value = newTab
}
return {
changeTab,
tab
}
}
}
</script>
我使用 脚本设置 的方法失败了:
My approach with the script setup fails:
<template>
<NavigationBar
@switchTab="changeTab"
:activeTab="tab"
/>
<component :is="tab" />
</template>
<script setup>
import NavigationBar from './components/NavigationBar.vue'
import TemplateSyntax from './components/TemplateSyntax.vue'
import DataPropsAndMethods from './components/DataPropsAndMethods.vue'
import { ref } from 'vue'
const tab = ref('DataPropsAndMethods')
function changeTab (newTab) {
tab.value = newTab
}
</script>
你知道如何用脚本设置方法解决这个问题吗?
