How to Display Text-Field Validation Check Results in Snackbar with Vuetify.js

Are you working on a customer form using Vuetify.js and struggling with displaying validation message results effectively? If so, you're not alone. Many developers encounter challenges when trying to implement validation checks for text fields and want to provide immediate feedback through a snackbar notification. In this post, we’ll guide you through a straightforward method to achieve this.

The Problem: Validation Feedback

In our example, we want to create a form that includes:

A text field for the user's name.

A text field for the user's email address.

Validation rules for both fields.

The goal is to validate the fields and display any error messages in a snackbar for better user experience. The built-in validation method in Vuetify is convenient, but it requires some customization to showcase the results in a snackbar.

The Solution: Step-by-Step Implementation

Here's how you can implement text-field validation and display the results in a snackbar using Vuetify.js.

Step 1: Setting Up the Template

First, we need our basic form structure. Here’s a simple setup using Vuetify components:

Step 2: Defining Data and Validation Rules

Next, you should define the reactive data properties in your script. This includes your form fields, validation rules, and snackbar state.

Step 3: Integrating the Validation Check

The core of our implementation is in the validate method. Here’s what the code is doing:

It references the form using this.$refs.form.

Calls the validate() method which checks all the fields against their respective rules.

If validation fails (returns false), it:

Sets the snackbar message (this.text) to a predefined error message.

Toggles the snackbar to true to display the snackbar.

Conclusion

With these steps, you can easily implement text-field validation checks in Vuetify.js and provide immediate feedback to users through a snackbar. This enhances user experience significantly and allows for better interaction with your forms.

Additional Tips

Customize your snackbar messages to be more dynamic by pulling specific error messages directly from your validation rules.

Style your snackbar and buttons to match your application’s theme for a cohesive user interface.

By implementing this simple method, you will ensure that your users receive clear and concise validation feedback, making for a more user-friendly experience in your application.
