如何在Vuejs中获取数组数据

<template>
  <div>
    <ul>
      <li v-for="item in arrayData" :key="item.id">{{ item.name }}</li>
    </ul>
  </div>
</template>

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

<template>
  <div>
    <ul>
      <li v-for="item in arrayData" :key="item.id">{{ item.name }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      rawData: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' }
      ]
    };
  },
  computed: {
    arrayData() {
      // 对原始数据进行处理，返回数组数据
      return this.rawData.filter(item => item.id > 1);
    }
  }
};
</script>

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

<script>
export default {
  data() {
    return {
      arrayData: [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' }
      ]
    };
  },
  methods: {
    getArrayData() {
      // 返回数组数据
      return this.arrayData;
    }
  }
};
</script>
