AngularJS Model

AngularJS Model

The ng-model directive is the backbone of user input in AngularJS.

It binds the value of an HTML control (like an input field) to application data.

What is ng-model?

When you attach ng-model to an input field, it creates a JavaScript variable.

Whatever the user types into that field is instantly saved into the variable.

You can then use that variable anywhere else in your application seamlessly!

Using ng-model

This directive works perfectly with inputs, textareas, and select dropdowns.

It provides built-in validation rules, checking for emails, numbers, and required fields.

It also provides CSS classes that let you style the input based on its valid state.

<div ng-app="">
  <p>Enter your username:</p>
  <!-- Creates a variable named 'user' -->
  <input type="text" ng-model="user">
  
  <!-- Instantly displays the 'user' variable -->
  <h3>Your username is: {{ user }}</h3>
</div>

SEO and Best Practices

Forms heavily utilize the ng-model directive to capture user data securely.

While forms don't directly impact SEO, proper accessible labels next to inputs do!

Always use semantic <label> tags alongside your ng-model inputs.
