javascript - VueJS，将数据从组件传递到另一个组件

Question

我为我做了一些新的东西，但我遇到了问题..所以让我们再解释一下..

我有一个名为 components/HomeComponent.vue

的组件

这里是:

HomeComponent.vue

<script>
export default {
  name: "HomeComponent",
  data() {
    posts: [
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" }
    ];
  }
};
</script>

我有我的“ View ”views/Home.vue

Home.vue

<template>
  <!-- Blog Entries Column -->
  <div class="col-md-8">
    <h1 class="my-4">Статии</h1>

    <!-- Blog Post -->
    <div class="card mb-4" v-for="post in posts">
      <div class="card-body">
        <h2 class="card-title">{{ post.title }}</h2>
        <p class="card-text">{{ post.body }}</p>
        <a href="#" class="btn btn-primary">Read More &rarr;</a>
      </div>
      <div class="card-footer text-muted">
        Posted on January 1, 2017 by
        <a href="#">xxx</a>
      </div>
    </div>
  </div>
</template>

所以我想访问我的 Home.vue 中的帖子并进行 for 循环..该怎么做？ 谢谢指教! :)

<script>
// @ is an alias to /src
import HomeComponent from "@/components/HomeComponent.vue";

export default {
  name: "home",
  components: {
    HomeComponent
  },
};
</script>

您必须将数据作为 props 传递给 Home 组件。更多信息可查询here 。但这里有一个快速解决您的问题的方法。

Comp.vue

<template>
  <!-- Blog Entries Column -->
  <div class="col-md-8">
    <h1 class="my-4">Статии</h1>

    <!-- Blog Post -->
    <div class="card mb-4" v-for="post in posts">
      <div class="card-body">
        <h2 class="card-title">{{ post.title }}</h2>
        <p class="card-text">{{ post.body }}</p>
        <a href="#" class="btn btn-primary">Read More &rarr;</a>
      </div>
      <div class="card-footer text-muted">
        Posted on January 1, 2017 by
        <a href="#">xxx</a>
      </div>
    </div>
  </div>
</template>

<script>
 export default {
   props:['posts']
 }
</script>

HomePage.vue

<template>
  <comp :posts="posts"></comp>
</template>

<script>
import Comp from './components/Comp.vue'
export default {
  name: "HomeComponent",
  components: {
    'comp': Comp
  },
  data() {
    posts: [
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" },
      { title: "Hello", body: "Some text" }
    ];
  }
};
</script>
