This article will discuss the differences between textarea and input directives with examples in AngularJS.

While working on web applications that contain forms, the new developers have questions regarding the difference between input and textarea. In this tutorial, we will discuss both in detail with examples.

Textarea Directive in AngularJS

There are many situations, such as building a contact form or creating blog posts and writing a dashboard, which has some fields in which we expect a user to write multiple lines. We use a textarea directive to allow users to write for multiple lines, sometimes with a limit of characters and sometimes without a limit of characters.

AngularJS change the default behavior of the <textarea> element, but only if the ng-model property is present. The ng-model supplies data-binding, which indicates they are part of the AngularJS model and can be directed to and updated in the AngularJS function and DOM.

Let us go through the example given below.

# AngularJS
<!DOCTYPE html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body ng-app="">

<label>Enter Message:</label><br>
<textarea ng-model="myTextarea"></textarea>

Input Directive in AngularJS

Input is an HTML used to get user input. Like textarea, input also used ng-model in an Angular directive for data binding. We can easily add an input by using the following code.

# AngularJS
<input ng-model="getName">

The most important thing in the input field is validation. The input tag uses the type property to define the type of input that a user can enter.

For example, if we want the user to input only an email in a specific field, we can assign the type of email, as shown below.

# angular
<input type="email" ng-model="getEmail">

Let’s go through an example and use both Input fields and the Textarea to check the difference.

# Angular
<!DOCTYPE html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
textarea.ng-invalid {
    background-color: yellow;
textarea.ng-valid {
    background-color: lightblue;
<body ng-app="">

<p>Enter Name</p>
<input type="text" ng-model="getName">

<p>Enter Message:</p>

<textarea ng-model="getMessage" required>

Differences Between Textarea and Input Directive in AngularJS

There are quite a few differences between the textarea and an input field, as discussed below.

  1. textarea allows us to get multiple lines from the user as input. But on the other hand, we can only get a limited input from users by using an input field.
  2. textarea allows us to limit the characters inserted in the text area. While on the other hand input field doesn’t allow us to limit the number of characters.
  3. The input field allows us to get validation and only allows users to enter the required data with the help of the type property.
