vue @vuelidate父子組件綁定注意事項(xiàng)

更新時(shí)間：2025年02月17日 15:29:34 作者：堅(jiān)定信念，勇往無(wú)前

Vue@vuelidate父子組件驗(yàn)證時(shí),不能直接綁定,需在子組件驗(yàn)證方法內(nèi)部進(jìn)行綁定,以避免父組件驗(yàn)證時(shí)包含子組件的驗(yàn)證

vue @vuelidate父子組件綁定注意

如果父子組件都有驗(yàn)證的，不能這樣寫(xiě)

	const V2$ = useVuelidate(rules, formdata)
	const submitBtn = async () => {
		const V2$ = useVuelidate(rules, formdata)

如果這樣寫(xiě)的話，在父組件驗(yàn)證時(shí)，也會(huì)把子組件的驗(yàn)證代上。

正確寫(xiě)法

	const submitBtn = async () => {
		const V2$ = useVuelidate(rules, formdata)
		 let validate =await V2$.value.$validate()

要在自己驗(yàn)證的方法內(nèi)部進(jìn)行綁定

Vuelidate表單驗(yàn)證規(guī)則

Vuelidate中的必填驗(yàn)證規(guī)則

用到的技術(shù) vue + quasar + vuelidate(網(wǎng)址)

引用方法如下：

 Vue.use(window.vuelidate.default)
 var minLength = window.validators.minLength
 var required = window.validators.required 
 var requiredIf = window.validators.requiredIf
 var email = window.validators.email
 var helpers = window.validators.helpers

 validations: {
	baseInfoForm: {
        mobilePhone:{ required: required },        
        col19:{ required: required },                 
        kitchenTime:{  required: requiredIf(function(baseInfoForm) {
          return baseInfoForm.col19 == 'Y'  
          //當(dāng)col19的值為Y時(shí),才有kitchenTime的驗(yàn)證
        })}        


  }

一個(gè)簡(jiǎn)單的例子：

<q-field 
icon="stay_primary_portrait"
:error="readonly == false? $v.baseInfoForm.mobilePhone.$error: false"
error-label="手機(jī)號(hào)碼不能為空"  //警告提示信息
class="col-lg-4 col-md-6 col-sm-12 col-xs-12">
  <q-input
   :readonly="readonly"  
   @blur="$v.baseInfoForm.mobilePhone.$touch"
   :float-label="$t('手機(jī)號(hào)碼')"
   type="number"
   v-model="baseInfoForm.mobilePhone"></q-input>
</q-field>
<q-field
v-if="baseInfoForm.col19 == 'Y' "
icon="access_time"
:error="readonly == false? $v.baseInfoForm.kitchenTime.$error: false"
error-label="進(jìn)入廚電行業(yè)時(shí)間不能為空"
class="col-lg-4 col-md-6 col-sm-12 col-xs-12">
  <q-datetime
   type="date"
   format="YYYY-MM-DD"
   format-model="string"
   :float-label="$t('若是,進(jìn)入廚電行業(yè)時(shí)間')"
   @blur="$v.baseInfoForm.kitchenTime.$touch"
    v-model="baseInfoForm.kitchenTime"></q-datetime>
</q-field>

效果如下：

具體代碼實(shí)現(xiàn)如下：

    <div id="q-supplierBaseInfo" v-cloak>
      <q-field 
   		icon="stay_primary_portrait"
        :error="readonly == false? $v.baseInfoForm.mobilePhone.$error: false"
        error-label="手機(jī)號(hào)碼不能為空"
        class="col-lg-4 col-md-6 col-sm-12 col-xs-12">
        <q-input
          :readonly="readonly"  
           @blur="$v.baseInfoForm.mobilePhone.$touch"
           :float-label="$t('手機(jī)號(hào)碼')"
           type="number"
           v-model="baseInfoForm.mobilePhone"></q-input>
      </q-field>
      <q-field 
         icon="work"
         :error="readonly == false? $v.baseInfoForm.col19.$error: false"
         error-label="是否為供應(yīng)商不能為空"
         class="col-lg-4 col-md-6 col-sm-12 col-xs-12">
         <q-select
           @blur="$v.baseInfoForm.col19.$touch"
           :float-label="$t('是否為供應(yīng)商')"
           :options="col19Options"
           v-model="baseInfoForm.col19"></q-select>
      </q-field>       
    </div>

      Vue.use(window.vuelidate.default)
      var minLength = window.validators.minLength
      var required = window.validators.required

      var helpers = window.validators.helpers
      var supplierInvite = new Vue({

              },

                label: '否',
                value: 'N'
              }
            ],
            baseInfoForm: { col19:''}
        },
        validations: {
          baseInfoForm: {
            col19:{ required: required },            
            kitchenTime:{  required: requiredIf(function(baseInfoForm) {
              return baseInfoForm.col19 == 'Y'           
            })}                                       
          }
        }
      })
