在vue.js v-validate中不使用多选

<input type="checkbox" v-model="selectedOptions" value="option1"> Option 1
<input type="checkbox" v-model="selectedOptions" value="option2"> Option 2
<input type="checkbox" v-model="selectedOptions" value="option3"> Option 3

data() {
  return {
    selectedOptions: []
  }
}

<input type="checkbox" v-model="selectedOptions" value="option1" v-validate="'required'"> Option 1
<input type="checkbox" v-model="selectedOptions" value="option2" v-validate="'required'"> Option 2
<input type="checkbox" v-model="selectedOptions" value="option3" v-validate="'required'"> Option 3

methods: {
  submitForm() {
    this.$validator.validateAll().then(result => {
      if (result) {
        // 表单验证通过，执行提交操作
      } else {
        // 表单验证失败，处理错误信息
      }
    });
  }
}
