How can I reference a function in a single file component using Vue.js?

Question

How can I reference a function in a single file component using Vue.js?

Within my Vue.js project, I have crafted a single file component known as Password.vue which comprises two password fields along with their associated validation checks.

To begin with, I structure my HTML within the

<template></template>

tags, and this element performs as expected.

Next, the JavaScript code is defined in the following manner:

<script>

    computed: {
        passwordsValid() {

           // Implement password validation logic here
        }
    },

};
</script>

A signup function imports the Password.vue component:

import PasswordComponent from "../components/Password.vue";

In the signup.html document, I embed

<password-component></password-component>

This inclusion is done to utilize the actual password component.

However, a challenge arises when trying to access the passwordsValid function from within the signup.html file since it resides inside the Password.vue component.

The query at hand is how can I overcome this barrier? Essentially, what steps should be taken to access functions that are enclosed within a single file component?

Answer №1

Define properties for Password.vue:

props: {
  requestCheckPassword: Boolean,
}

Include watch functionality:

watch: {
  requestCheckPassword () {
    this.$emit('passwordResult', {isValid: this.passwordsValid})
    this.$emit('update:requestCheckPassword', false)
  }
}

Next, in the signup.html file:

<password-component @passwordResult="methodFromMethodsSection" :request-check-password.sync="requestCheckPassword"></password-component>

Lastly, add the following code to the signup.html file:

data () {
  return {
    requestCheckPassword: false
  }
},
methods: {
  methodFromMethodsSection ({ isValid }) {
    // your logic, you can access isValid
  }
}

To receive the password check result, simply change the requestCheckPassword value in the data property. For example:

<button @click="requestCheckPassword = true">Click me</button>
