参考这个案例试试看：

    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm">提交</el-button>
    </el-form-item>
  </el-form>
</template>
 
<script>
  export default {
    data() {
      return {
        form: {
          username: ''
        },

                  rule.required = true;
                } else {

                  rule.required = false;
                }
                this.$refs.myForm.validateField('username');
                callback();

              trigger: 'blur'
            }
          ]
        }

    },
    methods: {
