vue实现列表demo

以下是一个基于 Vue.js 的列表实现示例，包含基础功能与关键代码解析：

基础列表渲染

<template>
  <div>
    <ul>
      <li v-for="(item, index) in items" :key="index">
        {{ item.name }}
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [
        { name: 'Item 1' },
        { name: 'Item 2' },
        { name: 'Item 3' }
      ]
    }
  }
}
</script>

带交互功能的列表

<template>
  <div>
    <button @click="addItem">Add Item</button>
    <ul>
      <li v-for="(item, index) in items" :key="item.id">
        {{ item.text }}
        <button @click="removeItem(index)">×</button>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [
        { id: 1, text: 'Sample Item 1' },
        { id: 2, text: 'Sample Item 2' }
      ],
      nextId: 3
    }
  },
  methods: {
    addItem() {
      this.items.push({
        id: this.nextId,
        text: `New Item ${this.nextId}`
      })
      this.nextId++
    },
    removeItem(index) {
      this.items.splice(index, 1)
    }
  }
}
</script>

动态样式绑定

<template>
  <ul>
    <li 
      v-for="item in filteredItems" 
      :key="item.id"
      :class="{ 'active': item.isActive }"
      @click="toggleActive(item)"
    >
      {{ item.name }}
    </li>
  </ul>
</template>

<script>
export default {
  data() {
    return {
      items: [
        { id: 1, name: 'Apple', isActive: false },
        { id: 2, name: 'Banana', isActive: true }
      ]
    }
  },
  computed: {
    filteredItems() {
      return this.items.filter(item => item.name.includes('a'))
    }
  },
  methods: {
    toggleActive(item) {
      item.isActive = !item.isActive
    }
  }
}
</script>

<style>
.active {
  background-color: #f0f0f0;
  font-weight: bold;
}
</style>

服务端数据获取

<template>
  <div v-if="loading">Loading...</div>
  <ul v-else>
    <li v-for="post in posts" :key="post.id">
      <h3>{{ post.title }}</h3>
      <p>{{ post.body }}</p>
    </li>
  </ul>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      posts: [],
      loading: true
    }
  },
  async created() {
    try {
      const response = await axios.get('https://jsonplaceholder.typicode.com/posts')
      this.posts = response.data.slice(0, 5)
    } catch (error) {
      console.error(error)
    } finally {
      this.loading = false
    }
  }
}
</script>
