表单提交后验证重置

Question

我有带复选框的表单，我希望用户 select 至少选择其中一个。一切正常，但在重置表单后我无法隐藏验证消息。这种情况在 docs 中有准确描述，但提供的解决方案似乎无效，因为在提交表单验证错误后出现。

    <template>
      <v-app>
        <v-content>
          <playground></playground>
          <v-card class="mx-auto" outlined>
            <ValidationObserver ref="obs" v-slot="{ invalid, valid, validated, passes, reset }">
              <v-card-title class="pb-0">Meal types</v-card-title>
              <v-row justify="center">
                <v-col cols="11">
                  <v-form ref="form">
                    <ValidationProvider rules="required" v-slot="{ errors, failedRules }">
                      <v-container row pa-0>
                        <v-row justify="space-around">
                          <v-checkbox
                            v-model="mealType"
                            value="BREAKFAST"
                            label="Breakfast"
                            hide-details
                          ></v-checkbox>
                          <v-checkbox v-model="mealType" value="DINNER" label="Dinner" hide-details></v-checkbox>
                          <v-checkbox v-model="mealType" value="SUPPER" label="Supper" hide-details></v-checkbox>
                          <v-checkbox v-model="mealType" value="SNACK" label="Snack" hide-details></v-checkbox>
                        </v-row>
                      </v-container>
                      <v-row justify="center">
                        <v-alert
                          v-if="failedRules.required"
                          type="error"
                          dense
                          outlined
                          class="mt-4 mb-0"
                        >Select at least one meal type</v-alert>
                      </v-row>
                    </ValidationProvider>
                  </v-form>
                </v-col>
              </v-row>
              <v-card-actions>
                <v-row justify="center">
                  <v-btn text color="deep-purple accent-4" @click="passes(addRecipe)">Save</v-btn>
                  <v-btn @click="reset">Reset</v-btn>              
                </v-row>
              </v-card-actions>
            </ValidationObserver>
          </v-card>
        </v-content>
      </v-app>
    </template>

    <script>
    import Playground from "./components/Playground";

    export default {
      name: "App",
      components: {
        Playground
      },
      data() {
        return {
          recipeName: "",
          mealType: []
        };
      },
      methods: {
        addRecipe() {
          console.log("add recipe");
          // after save or reset alerts should disappear..
          this.$refs.form.reset();
          requestAnimationFrame(() => {
            this.$refs.obs.reset();
          });
        }
      }
    };
    </script>

具有重现用例的代码沙箱：https://codesandbox.io/s/vee-validate-3-reset-checkbox-validation-qr8uw 请 select 一些餐食类型并点击保存。单击保存按钮后，表单将重置并显示验证消息，但事实并非如此。如何解决？

找到了解决办法，可以帮你解决问题（原文为this.$refs.form.reset()），肯定是个bug，应该反馈给VeeValidate解决。

我发现制作方法 async，并手动重置变量使一切都成功了。

methods: {
  async addRecipe() {
    console.log("add recipe");
    console.log(this.mealType);

    this.mealType = [];
    this.$refs.obs.reset();
  }
}
