我實施了評論中提出的更改。它現在正在作業！非常感謝大家的幫助
------------ 初始幫助請求如下： -----------
我有一個用作主頁的 Home.vue 父組件。在此頁面上，我發出一個獲取帖子陣列的請求。我嘗試使用 v-for 遍歷帖子陣列并每次發送一個新的帖子物件。
我的問題如下：
- 陣列被完整發送，因此只生成一個 Post 模板......
提前感謝您的時間，我做了一些研究，但沒有任何成功。
找到下面的 Home.vue 父組件
<template>
<div >
<div v-for="(post, index) in posts" :key="index">
<ImageArticle
:articledata="post"
/>
</div>
</div>
</template>
<script>
import ImageArticle from "../components/imageArticle"
import { mapState } from "vuex"
export default {
name: 'Home',
components: {
ImageArticle,
},
data() {
return {
posts : [],
}
},
computed: {
...mapState({
UserName: "UserName",
UserLogin: "UserLogin",
UserEmail: "UserEmail",
UserPublications: "UserPublications",
UserFriends: "UserFriends"
})
},
created() {
this.getAllPosts()
},
methods:{
getAllPosts () {
var requestOptions = {
method: 'GET',
redirect: 'follow'
};
fetch("http://localhost:3000/api/post/", requestOptions)
.then(response => response.text())
.then((result) => {
this.posts = JSON.parse(result);
console.log(this.posts);
})
.catch(error => console.log('error', error));
}
}
}
</script>
在子組件下方找到我嘗試將 post 物件作為道具發送到的子組件。（我洗掉了很多代碼，使其更具可讀性）
<template>
<div>
<article >
<h4 >Kaerbran {{articleData.Post_Comment}}</h4>
</article>
</div>
</template>
<script>
import ModalBoxActionArticle from '../components/modalBoxActionArticle'
export default {
name: 'ImageArticle',
props : ['articledata'],
data() {
return {
articleData : this.articledata,
}
}
}
</script>
在我發送的陣列下方找到。我想為每個 Post_ID 創建一個新模板。

uj5u.com熱心網友回復：
需要注意的幾點：
首先，為迭代元素傳遞鍵的方式是錯誤的。陣列的傳遞和索引會導致不可預測的結果或 ui 未更新。將這一行從
v-bind:key="{index}"
到
v-bind:key="post.Post_ID"
然后，您將資料傳遞給道具的方式也是錯誤的，從
v-bind:sendArticleData = post
到
v-bind:send-article-data="post"
甚至更簡單地：
:send-article-data="post"

如果我理解正確，請嘗試以下代碼段：
Vue.component('Child', {
template: `
<div >
<div >
<h4 >Kaerbran {{articleData.Post_Comment}}</h4>
</div>
</div>
`,
props : ['articledata'],
data() {
return {
articleData : this.articledata,
}
}
})
new Vue({
el: '#demo',
data() {
return {
