Vuetify 表单验证——定义匹配输入的 ES6 规则

Question

我有一个带有电子邮件输入的 (Vuetify) 表单，该表单使用 ES6 和正则表达式来检查它是否是有效的电子邮件。我将如何设置另一个 emailConfirmationRules 规则集来检查 emailConfirmation 输入是否与 email 输入匹配？

<template>
  <v-form v-model="valid">
       <v-text-field label="Email Address"
            v-model="email" 
            :rules="emailRules"
            required></v-text-field>

       <v-text-field label="Confirm Email Address"
            v-model="emailConfirmation" 
            :rules="emailConfirmationRules"
            required></v-text-field>
   </v-form>
 <template>

export default {
    data () {
      return {
         valid: false,
         email: '',
         emailConfirmation: '',
         emailRules: [
             (v) => !!v || 'E-mail is required',
             (v) => /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(v) || 'E-mail must be valid'
        ],
        emailConfirmationRules: [
            (v) => !!v || 'Confirmation E-mail is required',
        ]   (v) => ??? || 'Confirmation E-mail does not match'
    }
}

Answer 1

  emailConfirmationRules: [
    (v) => !!v || 'Confirmation E-mail is required',
    (v) => v == this.email || 'E-mail must match'
  ],

Answer 2

规则不是处理字段确认的正确方法。 emailConfirmationRules 仅在 emailConfirmation 更改时触发，但如果您再次更改 email，您的字段将不会继续比赛，不违反规则。

您必须手动处理：

methods: {
  emailMatchError () { 
    return (this.email === this.emailConfirmation) ? '' : 'Email must match'
  }
}

<v-text-field v-model='emailConfirmation' :error-messages='emailMatchError()'></v-text-field>

可能还有一种使用 vee-validate 执行此操作的替代方法。

Answer 3

您可以使用计算规则完成相同的操作。

computed: {
    emailConfirmationRules() {
      return [
        () => (this.email === this.emailToMatch) || 'E-mail must match',
        v => !!v || 'Confirmation E-mail is required'
      ];
    },
}

Answer 4

  <template>   
    <v-text-field
      v-model="employee.email"
      :rules="emailRules"
      required
      validate-on-blur
      />
</template>

<script>
data() {
    return {
    emailRules: [
        v => !!v || "E-mail is required",
        v =>
          /^\w+([.-]?\w+)*@\w+([.-]?\w+)*(\.\w{2,3})+$/.test(v) ||
          "E-mail must be valid"
      ],
}
</script>

Answer 5

检查这个post

<template>
  <v-input  v-model="firstPassword" />
  <v-input :rules=[rules.equals(firstPassword)] v-model="secondPassword" />
</template>

<script>    
  data() {
  firstPassword: '',
  secondPassword: '',
    rules: {
      equals(otherFieldValue) {
        return v =>  v === otherFieldValue || 'Not equals';
      }
    }
  }
</script>
