• 先展示修改后可校验的完整 demo

  <template>
    <div class="rules-container">
      <a-form-model
        ref="formRef"
        :model="formState"
        :rules="rules"
        :label-col="labelCol"
        :wrapper-col="wrapperCol"
      >
        <a-form-model-item label="Activity name" prop="name">
          <a-input v-model="formState.name" />
        </a-form-model-item>
        <a-form-model-item :wrapper-col="{ span: 14, offset: 4 }">
          <a-button type="primary" @click="onSubmit">Create</a-button>
        </a-form-model-item>
      </a-form-model>
    </div>
  </template>
  <script>
  export default {
    name: 'Test',
    data() {
      return {
        formState: {
          name: '',
        },
        rules: {
          name: [
            { required: true, message: 'Please input Activity name', trigger: 'blur' }
          ]
        },
        labelCol: {
          span: 4,
        },
        wrapperCol: {
          span: 14,
        },
      }
    },
    methods: {
      onSubmit() {
        this.$refs.formRef.validate(valid => {
          if(valid) {
            console.log('values');
          } else{
            console.log('error submit!!')
            return false
          }
        })
      }
    }
  }
  </script>
