在两个select标签之间创建vuejs表单输入依赖项

data() {
  return {
    select1Value: '',
    select2Value: '',
  }
}

<select v-model="select1Value">
  <!-- select1 options -->
</select>

<select v-model="select2Value">
  <!-- select2 options -->
</select>

computed: {
  select2Options() {
    // 根据select1Value生成select2的选项列表
    if (this.select1Value === 'option1') {
      return ['option1-1', 'option1-2', 'option1-3'];
    } else if (this.select1Value === 'option2') {
      return ['option2-1', 'option2-2', 'option2-3'];
    } else {
      return [];
    }
  }
}

watch: {
  select1Value(newValue) {
    this.select2Value = '';
  }
}
