Vue 实现车次信息功能

数据结构设计

车次信息通常包含车次编号、出发站、到达站、出发时间、到达时间、历时、座位类型及价格等字段。建议使用如下数据结构：

trainList: [
  {
    trainNo: 'G1234',
    from: '北京',
    to: '上海',
    departTime: '08:00',
    arriveTime: '12:30',
    duration: '4小时30分',
    seats: [
      { type: '二等座', price: 553 },
      { type: '一等座', price: 933 }
    ]
  }
]

组件化开发

创建独立的车次信息组件（TrainItem.vue）：

<template>
  <div class="train-item">
    <div class="train-header">
      <span class="train-no">{{ data.trainNo }}</span>
      <span class="train-route">{{ data.from }} - {{ data.to }}</span>
    </div>
    <div class="train-time">
      <span>{{ data.departTime }}</span>
      <span class="duration">{{ data.duration }}</span>
      <span>{{ data.arriveTime }}</span>
    </div>
    <div class="train-seats">
      <div v-for="seat in data.seats" :key="seat.type" class="seat-item">
        <span>{{ seat.type }}</span>
        <span>¥{{ seat.price }}</span>
      </div>
    </div>
  </div>
</template>

数据获取与渲染

通过API获取数据并在父组件中渲染：

export default {
  data() {
    return {
      trains: []
    }
  },
  async created() {
    try {
      const res = await axios.get('/api/trains')
      this.trains = res.data
    } catch (error) {
      console.error('获取车次数据失败', error)
    }
  }
}

样式优化

使用CSS Grid布局实现响应式设计：

.train-item {
  display: grid;
  grid-template-columns: 1fr 2fr 1fr;
  gap: 16px;
  padding: 12px;
  border-bottom: 1px solid #eee;
}

.train-time {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.duration {
  color: #999;
  font-size: 0.9em;
}

.seat-item {
  display: flex;
  justify-content: space-between;
  margin-bottom: 8px;
}

交互功能增强

添加车次筛选和排序功能：

vue实现车次信息

computed: {
  filteredTrains() {
    return this.trains.filter(train => {
      return train.from.includes(this.searchQuery) || 
             train.to.includes(this.searchQuery) ||
             train.trainNo.includes(this.searchQuery)
    }).sort((a, b) => {
      if (this.sortBy === 'time') {
        return a.departTime.localeCompare(b.departTime)
      } else if (this.sortBy === 'price') {
        return a.seats[0].price - b.seats[0].price
      }
      return 0
    })
  }
}
