问题描述
我是 Vue 的新手,我收到一个错误,不明白为什么以及如何解决这个问题。 我在控制台中得到的错误是:无法读取未定义的属性“状态”
我正在使用 vue 版本 @vue/cli 4.5.12
这是我拥有的文件:
main.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router.js'
import {store} from './store.js'
const app = createApp(App)
app.use(router,store)
app.mount('#app')
store.js
import { createStore } from 'vuex'
const store = createStore ({
state() {
return {
socialIcons: {
github: {
icon: "/../assets/images/Github.svg",name: "Github",link: "https://github.com/Roene"
},linkedin: {
icon: "/../assets/images/LinkedIn.svg",name: "Linkedin",link: "https://www.linkedin.com/in/roene-verbeek/"
},instagram: {
icon: "/../assets/images/Instagram.svg",name: "Instagram",link: "https://www.instagram.com/roeneverbeek/"
}
}
}
}
})
export default store
Home.vue
<template>
<section class="home">
<div class="title">
<h1 class="nameTitle">{{name}}</h1>
<h2 class="jobTitle">{{jobTitle}}</h2>
<div class="icons">
<div class="icon">
<a
target="_blank"
v-for="icon in socialIcons"
class="icon"
:href="icon.link"
:key="icon.name"
>
<span class="iconName">{{icon.name}}</span>
<img class="iconImage" :src="icon.icon" :alt="icon.name">
</a>
</div>
</div>
</div>
<div class="photo">
</div>
</section>
</template>
<script>
export default {
data() {
return {
name: "Roene Verbeek",jobTitle: "Front-end developer",socialIcons: this.$store.state.socialIcons
}
}
}
</script>
解决方法
use
方法接受一个插件作为第一个参数和选项(这是可选的)作为第二个 app.use(plugin,itsOptions)
,所以你应该这样做:
import store from './store.js'// without {} since you did export default in your store
...
app.use(router).use(store)
和 socialIcons
必须是计算属性:
export default {
data() {
return {
name: "Roene Verbeek",jobTitle: "Front-end developer",}
},computed:{
socialIcons(){
return this.$store.state.socialIcons
}
}
}
