Form 表单 0.2.0 ​

用于数据录入、校验，支持输入框、单选框、复选框、文件上传等类型，常见的 form 表单为单元格形式的展示，即左侧为表单的标题描述，右侧为表单的输入。

其中，Input 输入框、Textarea 输入框、Picker 选择器、 Calendar 日历选择器、 ColPicker 多列选择器、SelectPicker 单复选选择器、Cell 单元格 和 DatetimePicker 日期时间选择器具有单元格的展示形式，同时也支持 prop 和 rules 属性，我们称之为表单项组件，而 InputNumber 计数器 、 Switch 开关 和 Upload 上传 等组件则需要使用 Cell 单元格 进行包裹使用。

结合 wd-form 组件，可以实现对以上组件的规则校验。

对于表单组件，建议对 wd-cell-group 开启 border 属性，这样每条 cell 就会有边框线隔离开，这样表单的划分比较清晰。

基础用法 ​

在表单中，使用 model 指定表单数据对象，每个 表单项组件 代表一个表单项，使用 prop 指定表单项字段 ，使用 rules 属性定义校验规则。

查看基础用法示例
html
<wd-form ref="form" :model="model">
  <wd-cell-group border>
    <wd-input
      label="用户名"
      label-width="100px"
      prop="value1"
      clearable
      v-model="model.value1"
      placeholder="请输入用户名"
      :rules="[{ required: true, message: '请填写用户名' }]"
    />
    <wd-input
      label="密码"
      label-width="100px"
      prop="value2"
      show-password
      clearable
      v-model="model.value2"
      placeholder="请输入密码"
      :rules="[{ required: true, message: '请填写密码' }]"
    />
  </wd-cell-group>
  <view class="footer">
    <wd-button type="primary" size="large" @click="handleSubmit" block>提交</wd-button>
  </view>
</wd-form>
typescript
<script lang="ts" setup>
const { success: showSuccess } = useToast()

const model = reactive<{
  value1: string
  value2: string
}>({
  value1: '',
  value2: ''
})

const form = ref()

function handleSubmit() {
  form.value
    .validate()
    .then(({ valid, errors }) => {
      if (valid) {
        showSuccess({
          msg: '校验通过'
        })
      }
    })
    .catch((error) => {
      console.log(error, 'error')
    })
}
</script>
css
.footer {
  padding: 12px;
}

校验错误提示方式 ​

  1. message：默认为输入框下方用文字进行提示
  2. toast：以"toast"提示的方式弹出错误信息，每次只弹出最前面的那个表单域的错误信息
  3. none：不会进行任何提示

校验规则 ​

本章节演示四种自定义校验及提示规则：正则校验、函数校验、函数返回错误提示和异步函数校验。

    <wd-input

const form = ref()

const validatorMessage = (val) => {
  return /1\d{10}/.test(val)
}

const validator = (val) => {
  if (String(val).length >= 4) {
    return Promise.resolve()
  } else {
    return Promise.reject('长度不得小于4')
  }
}

// 校验函数可以返回 Promise，实现异步校验
const asyncValidator = (val) =>
  new Promise((resolve) => {
    showLoading('验证中...')

    setTimeout(() => {
      closeToast()
      resolve(val === '1234')
    }, 1000)
  })

function handleSubmit() {

    .validate()
    .then(({ valid, errors }) => {

    .catch((error) => {
      console.log(error, 'error')
    })
}
</script>

动态表单 ​

表单项动态增减。

      v-model="item.value"
      placeholder="玛卡巴卡单号"
      :rules="[{ required: true, message: '请填写玛卡巴卡单号' + index }]"
    />

typescript
<script lang="ts" setup>
import { useToast } from '@/uni_modules/wot-design-uni'
import { reactive, ref } from 'vue'

interface PhoneItem {
  key: number
  value: string
}

const model = reactive<{
  name: string
  phoneNumbers: PhoneItem[]
}>({
  name: '',
  phoneNumbers: [
    {
      key: Date.now(),
      value: ''
    }
  ]
})

const { success: showSuccess } = useToast()
const form = ref()

const removePhone = () => {
  model.phoneNumbers.splice(model.phoneNumbers.length - 1, 1)
}

const addPhone = () => {
  model.phoneNumbers.push({
    key: Date.now(),
    value: ''
  })
}

const reset = () => {
  form.value.reset()
}

const submit = () => {
  form.value.validate().then(({ valid, errors }) => {
    if (valid) {
      showSuccess('校验通过')
    }
  })
}
</script>
css
.footer {
  text-align: left;
  :deep(.wd-button) {
    &:not(:last-child) {
      margin-right: 12px;
    }
  }
}

指定字段校验 ​

validate 方法可以传入一个 prop 参数，指定校验的字段，可以实现在表单组件的blur、change等事件触发时对该字段的校验。

<wd-form ref="form" :model="model" errorType="toast">
  <wd-cell-group border>
    <wd-input
      label="用户名"

      prop="value1"
      clearable

      placeholder="请输入用户名"
