【问题描述】：
我实施了 cmets 中提出的更改。它现在正在工作！非常感谢大家的帮助
------------ 下面的初始帮助请求：--------
我有一个 Home.vue 父组件用作主页。在此页面上，我发出获取请求以获取一系列帖子。我尝试使用 v-for 遍历帖子数组并每次发送一个新的帖子对象。
我的问题如下：
- 数组已完整发送，因此仅生成一个 Post 模板...
非常感谢您抽出宝贵时间，我做了一些研究，但没有任何成功。
在 Home.vue 父组件下方查找
<template>
<div class="home">
<div v-for="(post, index) in posts" :key="index">
<ImageArticle
:articledata="post"
class="home__component"/>
</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>
在子组件下方查找，我尝试将 post 对象作为道具发送到该子组件。 （我删除了很多代码，使其更具可读性）
<template>
<div>
<article class="postWithImage">
<h4 class="postWithImage__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>
在我发送的数组下方查找。我想为每个 Post_ID 创建一个新模板。

【问题讨论】：
-
你的问题有点不清楚，就像你所说的数组被完整发送，因此只生成一个帖子模板......是什么意思？各种问题
v-bind:sendArticleData = post，应该是v-bind:sendArticleData="post"或只是:sendArticleData="post"也Posts : "",是错误的初始类型如果它最终是一个数组，它应该是Posts : [], -
那么问题出在哪里？
-
this.articleData 在子级，仍然向我发送完整的数组。我还尝试了@Nikola Pavicevic 的解决方案。但它仍然没有遍历数组的所有对象。
-
在@Nikola Pavicevic 发送的 sn-p 中，它运行良好！
