Materialize – Material Angular JS Forms

Introduction

Materialize is a popular CSS framework that provides a wide range of UI components and tools to build robust and responsive web applications. Materialize Angular is an official wrapper for Materialize that integrates the framework with Angular, a popular JavaScript framework for building web applications.

One of the essential components of any web application is forms. Materialize provides a robust form validation system that makes it easy to create and validate forms. In this tutorial, we will explore how to use Materialize Angular forms and learn how to create, validate, and submit forms using Materialize Angular.

Prerequisites

To follow this tutorial, you should have:

• Basic knowledge of HTML, CSS, and JavaScript
• Familiarity with Angular and Materialize
• Materialize Angular installed in your project

Step 1: Create a Basic Form

To create a basic form using Materialize Angular, you need to create an HTML file with a <form> tag. Here's an example of a basic form:

<form>
  <div class="row">
    <div class="input-field col s12">
      <input type="text" id="name" />
      <label for="name">Name</label>
    </div>
  </div>
  <div class="row">
    <div class="input-field col s12">
      <input type="email" id="email" />
      <label for="email">Email</label>
    </div>
  </div>
  <button class="btn">Submit</button>
</form>

This form has two input fields: name and email, and a submit button. We have also added Materialize CSS classes to the form fields and the submit button to style them.

Step 2: Add Materialize Angular Form Directive

To enable Materialize form validation, you need to add the form-directive from Materialize Angular to your HTML file. Here's how you can do it:

<form md-form>
  <!-- form fields go here -->
</form>

The md-form directive is used to wrap your form fields and enable Materialize form validation. Make sure to include the md-form directive before the form fields.

Step 3: Add Form Fields

Add the form fields inside the md-form directive. Here's an example:

<form md-form>
  <md-input-container>
    <label>Username</label>
    <input type="text" mdInput>
  </md-input-container>
  <md-input-container>
    <label>Email</label>
    <input type="email" mdInput>
  </md-input-container>
  <button class="btn" md-button>Submit</button>
</form>

In this example, we have added two md-input-container elements to wrap the form fields. The md-input directive is used to create a Materialize input field.

Step 4: Add Validation

To add validation to your form, you can use the md-validate directive on the form fields. Here's an example:

<form md-form>
  <md-input-container>
    <label>Username</label>
    <input type="text" mdInput [mdValidate]="required" required>
  </md-input-container>
  <md-input-container>
    <label>Email</label>
    <input type="email" mdInput [mdValidate]="required" required>
  </md-input-container>
  <button class="btn" md-button>Submit</button>
</form>

In this example, we have added the mdValidate directive to the form fields and set the validation to required. This will make the form fields mandatory.

Step 5: Add Error Messages

To display error messages, you can use the md-error directive on the form fields. Here's an example:

<form md-form>
  <md-input-container>
    <label>Username</label>
    <input type="text" mdInput [mdValidate]="required" required>
    <md-error>Username is required</md-error>
  </md-input-container>
  <md-input-container>
    <label>Email</label>
    <input type="email" mdInput [mdValidate]="required" required>
    <md-error>Email is required</md-error>
  </md-input-container>
  <button class="btn" md-button>Submit</button>
</form>

In this example, we have added the md-error directive to the form fields and set the error message to "Username is required" and "Email is required".

Conclusion

In this tutorial, we have learned how to create, validate, and submit forms using Materialize Angular. We have also learned how to add error messages to the form fields using the md-error directive. With these basics covered, you can start building robust and responsive forms using Materialize Angular.
