How to add password matching validation in vuetify?

To add password matching validation in Vuetify, you can use the rules property of the v-text-field component to define a custom validation function. Here's an example of how you can implement password matching validation in Vuetify:

1. Add two v-text-field components for entering the password and confirming the password:

1
2
3
4
5
6
7
8

<template>
  <v-app>
    <v-container>
      <v-text-field v-model="password" label="Password" type="password" required></v-text-field>
      <v-text-field v-model="confirmPassword" label="Confirm Password" type="password" required :rules="[passwordMatchRule]"></v-text-field>
    </v-container>
  </v-app>
</template>

1. Define a custom validation function in the data section of your Vue component:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

data() {
  return {
    password: '',
    confirmPassword: '',
    passwordMatchRule: (value) => {
      if (value !== this.password) {
        return 'Passwords do not match';
      }
      return true;
    }
  };
}

In this code snippet, we define a passwordMatchRule function that checks if the value entered in the "Confirm Password" field matches the password entered in the "Password" field. If the passwords do not match, the validation function returns an error message.

By setting the :rules attribute of the "Confirm Password" v-text-field component to the passwordMatchRule function, we ensure that the validation function is applied to this field. If the validation function returns an error message, Vuetify will display this message below the input field.

This way, you can easily add password matching validation in Vuetify by using custom validation functions with the rules property of the v-text-field component.
