How to use Vue to implement imitation Weibo comment effects
Vue.js is a popular JavaScript framework that simplifies front-end development and provides a wealth of tools and components to Build interactive user interfaces. In this article, I will show you how to use Vue.js to implement imitation Weibo comment effects and provide specific code examples.

The implementation of imitation Weibo comment effects mainly includes two aspects: one is to display the comment list, and the other is to add new comments. Below we will introduce in detail how to use Vue.js to achieve these two functions.

1. Display the comment list

First, we need to create a Vue component to display the comment list. Define an array comments in the data attribute of the component to store all comments. Each comment contains two attributes: name (nickname of the commenter) and content (comment content).

<template>
  <div>
    <h2>评论列表</h2>
    <ul>
      <li v-for="comment in comments" :key="comment.id">
        <strong>{{ comment.name }}：</strong>
        {{ comment.content }}
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      comments: [
        { id: 1, name: '张三', content: '这是一条评论' },
        { id: 2, name: '李四', content: '这是另一条评论' }
      ]
    };
  }
};
</script>

In the above code, we use Vue’s v-for directive to loop and render the comment list. By looping through the comments array, we can display all comments dynamically. Each li element has a unique key attribute to improve rendering performance.

2. Add new comment

Next, we need to add a new comment to the comments list. We can add an input box and submit button to the component's template. Users can enter comments in the input box and click the submit button to add them.

<template>
  <div>
    <h2>评论列表</h2>
    <ul>
      <li v-for="comment in comments" :key="comment.id">
        <strong>{{ comment.name }}：</strong>
        {{ comment.content }}
      </li>
    </ul>

    <div>
      <input v-model="newComment.name" placeholder="昵称" />
      <input v-model="newComment.content" placeholder="评论内容" />
      <button @click="addComment">添加评论</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      comments: [
        { id: 1, name: '张三', content: '这是一条评论' },
        { id: 2, name: '李四', content: '这是另一条评论' }
      ],
      newComment: { name: '', content: '' }
    };
  },
  methods: {
    addComment() {
      if (this.newComment.name.trim() !== '' && this.newComment.content.trim() !== '') {
        const id = this.comments.length + 1;
        this.comments.push({ ...this.newComment, id });
        this.newComment = { name: '', content: '' };
      }
    }
  }
};
</script>

In the above code, we use Vue’s v-model directive to implement two-way data binding. When the user enters the commenter's nickname and comment content in the input box, these data will be bound to the newComment object. When the submit button is clicked, the addComment method will be called, adding the data in the newComment object to the comments array, and clearing the input box.

So far, we have completed the steps of using Vue.js to implement the special effects of imitating Weibo comments. You can follow the above code example to create a comment component in your Vue project and customize it as needed.
