form扩展验证

[magnificent007]

关于form扩展验证问题，文档内只有单个字段，我想扩展多个字段的验证，rules 和 validateData 该以什么样的形式传入进行验证呢？

可以参考这里 https://github.com/varletjs/varlet/blob/dev/packages/varlet-ui/src/form/example/index.vue

里面有个 VarCustomFormComponent 组件，拓展多个可以参考这个组件封装

:rules="[() => model.name.length > 6 || 'Error', () => model.age > 10 || 'Error']" 也是一样的～

:rules="[() => model.name.length > 6 || 'Error', () => model.age > 10 || 'Error']" 也是一样的～

可以确定rules是个数组函数，我就是不清楚验证的数据要用什么格式？对象数组形式还是什么其它的格式？

查看了，但是还是不清楚，验证的数据需要什么格式？可以确定rules是个函数数组，验证的数据是否也要用对象数组？

不对验证数据格式有要求呀。本质 rules 是一个验证函数数组，组件自动判断验证时机，验证的时候只是执行函数，用户怎么写的就怎么执行。

不是的，您可能没理解我的意思。rules是个函数数组，我理解没有问题；我想知道的是要验证的数据 在多字段验证的情况下 需要传入什么格式？是对象数组还是其它形式？

没有格式要求。input 绑定的是什么值就验证什么值。

没有用input哦，里面是我自定义的多个输入操作，下面我提供下vue3代码片段和效果图

// 接入表单校验组件validate-form.tsx
import { Form } from '@varlet/ui'
import { nextTick, type SetupContext, type PropType } from 'vue'

type FComponentProps = {
  readonly?: Partial<boolean>,
  disabled?: Partial<boolean>,
  validateTrigger?: Partial<Array<string>>,
  rules?: Partial<Array<(v: any) => string | boolean>>,
  validateValues: Array<string>
}

type Events = {
  ['update:validateValues'](validateValues: Objectable): void,
  exposeFormInstance(i: Objectable): void
}

export type ExposeFormInstanceType = {
  reset: () => void, 
  trigger: () => void, 
  validate: () => Promise<boolean>, 
  resetValidation: () => void
}

export const ValidateForm = (props: FComponentProps, context: SetupContext<Events>) => {
  const { slots, emit, attrs } = context
  const { useForm, useValidation } = Form
  const { errorMessage, validateWithTrigger: _validateWithTrigger, validate: _validate, resetValidation } = useValidation()
  const { bindForm, form } = useForm()
  const validate = () => _validate(props.rules, props.validateValues)

  function reset() {
    emit('update:validateValues', [])
    resetValidation()
  }

  function validateWithTrigger(trigger: any) {
    nextTick(() => {
      const { validateTrigger, rules, validateValues } = props
      _validateWithTrigger(validateTrigger!, trigger, rules, validateValues)
    })
  }

  function trigger() {
    if (
      props.readonly ||
      props.disabled ||
      form?.readonly.value || 
      form?.disabled.value
    ) {
      return
    }
    emit('update:validateValues', props.validateValues)
    validateWithTrigger('onToggle')
  }

  emit('exposeFormInstance', { reset, trigger, validate, resetValidation })
  bindForm?.({ reset, validate, resetValidation })

  return (
    <>
      <var-space class="w-full z-99999" direction="column" size={[14, 0]}>
        { slots.main ? slots.main({ readonly: props.readonly, disabled: props.disabled, errorMessage: errorMessage.value }) : (<var-result type='empty' description='三无属性地带..！' />) }
        { slots.footer ? slots.footer({ readonly: props.readonly, disabled: props.disabled }) : (<></>) }
      </var-space>
    </>
  )
}

ValidateForm.props = {
  readonly: {
    type: Boolean as PropType<Partial<boolean>>,
    default: false
  },
  disabled: {
    type: Boolean as PropType<Partial<boolean>>,
    default: false
  },
  validateTrigger: {
    type: Array as PropType<Partial<Array<string>>>,
    default: () => ['onToggle']
  },
  rules: {
    type: Array as PropType<Partial<Array<(v: any) => string | boolean>>>,
    default: () => []
  },
  validateValues: {
    type: Array as PropType<Array<string>>,
    default: () => []
  }
}

export default ValidateForm

// 使用
<script lang='ts' setup>
import { ref } from 'vue'
import { ValidateForm, type ExposeFormInstanceType } from '@/components/basic/validate-form/validate-form'
import { pull } from 'lodash-es'

// ------------------ 验证从这里开始 ------------------

const { getFormInstance, validate } = useForm()
const { characteristic, checkedCharacter } = useSelectCharacter()

function useSelectCharacter() {
  const characteristic = ref<Array<string>>([])

  const checkedCharacter = (e: any, additional: { readonly: boolean, disabled: boolean }) => {
    if (additional.readonly || additional.disabled) return 
    const { id } = e.target.dataset
    if (characteristic.value.includes(id)) {
      pull(characteristic.value, id)
      return 
    }
    characteristic.value.push(id)
  }

  return {
    characteristic,
    checkedCharacter
  }
}

function useForm() {
  const formInstance = ref<ExposeFormInstanceType>()

  function getFormInstance(instance: ExposeFormInstanceType) {
    formInstance.value = instance
  }

  function validate() {
    formInstance.value?.validate()

我这边没问题，你这边提供的 tsx 代码可能存在问题，可以尝试按照图2修复。
