解决uniapp使用up-form组件，uView提示:未设置rules,请看文档说明!如果已经设置,请刷新页面。

up-form组件 :model="formData" :rules="rules"
rules中的属性在formData要赋初始值，比如下面的例子

表单样式

html 复制代码

          <up-form labelPosition="top" labelWidth="auto" :labelStyle="{ color: '#333333' }" :model="formData"
            :rules="rules" ref="formRef">
            <view class="form-item">
              <up-form-item borderBottom prop="userName" label="收货人">
                <up-input v-model="formData.userName" border="none" placeholder="请输入姓名" />
              </up-form-item>
            </view>
            <view class="form-item">
              <up-form-item borderBottom prop="phone" label="手机号吗">
                <up-input v-model="formData.phone" border="none" placeholder="请输入手机号吗" />
              </up-form-item>
            </view>
            <view class="form-item">
              <up-form-item borderBottom prop="address" label="收货地址">
                <up-input v-model="formData.address" border="none" placeholder="请输入详情地址" />
              </up-form-item>
            </view>
          </up-form>

✔正确代码

js 复制代码

const state = reactive({
  formData: {
    userName: '',
    phone: '',
    address: '',
  } as UserAddressUpdateReq,
  rules: {
    'userName': {
      type: 'string',
      required: true,
      message: '请输入姓名',
      trigger: ['blur', 'change']
    },
    'phone': [{
      type: 'string',
      required: true,
      message: '请输入手机号吗',
      trigger: ['blur', 'change']
    },
    {
      validator: (rule: any, value: any, callback: any) => {
        return uni.$u.test.mobile(value);
      },
      message: '手机号码不正确',
      trigger: ['change', 'blur'],
    }],
    'address': {
      type: 'string',
      required: true,
      message: '请输入详情地址',
      trigger: ['blur', 'change']
    }
  }
})
const { formData, rules } = toRefs(state)

❌错误代码

const state = reactive({
  formData: {} as UserAddressUpdateReq,
  rules: {
    'userName': {
      type: 'string',
      required: true,
