解决方案
Try below steps it will help you to fix the issue.
Step 1: Install vuelidate using npm install --save vuelidate
Step 2: Register vuelidate in main.js
import Vuelidate from 'vuelidate'
Vue.use(Vuelidate)
Step 3: Importrequired, email, minLength, sameAs from vuelidate/lib/validators
import { required, email, minLength, sameAs } from 'vuelidate/lib/validators'
Step 4: Add validations
validations: {
user: {
name: { required },
email: { required, email },
password: { required, minLength: minLength(6) },
confirmPassword: { required, sameAsPassword: sameAs('password') }
}
},
Step 4: Do the validation on button click
methods: {
submitRegistration () {
this.submitted = true
this.$v.$touch()
if (this.$v.$invalid) {
return false // stop here if form is invalid
} else {
alert('Form Valid')
}
}
}
Step 5: Design html template
<template>
<div>
<form @submit.prevent="submitRegistration" novalidate>
<div class="form-group">
<input type="text" class="form-control" placeholder="First Name" value="" v-model="user.name" />
<div v-if="this.submitted && !$v.user.name.required" class="invalid-feedback left">Enter Username</div>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="Enter your company email ID" value="" v-model="user.email" autocomplete="off"/>
<div v-if="this.submitted && $v.user.email.$error" class="invalid-feedback left">
<span v-if="!$v.user.email.required">Email is required</span>
<span v-if="user.email && !$v.user.email.email">Enter valid email address</span>
<span v-if="user.email && $v.user.email.email && !$v.user.email.maxLength">Email is allowed only 30 characters</span>
</div>
</div>
<div class="form-group">
<input type="password" class="form-control" placeholder="Enter Password" value="" v-model="user.password" autocomplete="off" />
<div v-if="this.submitted && $v.user.password.$error" class="invalid-feedback left">
<span v-if="!$v.user.password.required">Password is required</span>
<span v-if="user.password && !$v.user.password.minLength">Password must be minimum 6 characters</span>
</div>
</div>
<div class="form-group">
<input type="password" class="form-control" placeholder="Confirm Password" value="" v-model="user.confirmPassword" autocomplete="off" />
<div v-if="this.submitted && $v.user.confirmPassword.$error" class="invalid-feedback left">
<span v-if="!$v.user.confirmPassword.required">Confirm Password is required</span>
<span v-if="user.confirmPassword && !$v.user.confirmPassword.sameAsPassword">Password and Confirm Password should match</span>
</div>
</div>
<input type="submit" class="btnRegister" value="Register" :disabled="this.isDisabled" />
</form>
</div>
</template>
Step 6: Button disabled till the form is valid
created () {
this.submitted = true
return this.$v.$touch()
},
computed: {
isDisabled () {
return this.$v.$invalid
}
},
