Ionic Inputs

Ionic provides various input types that can be used to collect data from users. Inputs are generally used to get user inputs for text, number, password, email, etc.

Syntax

<ion-item>
  <ion-label position="floating">Label</ion-label>
  <ion-input type="text" [(ngModel)]="value"></ion-input>
</ion-item>

Example

<ion-item>
  <ion-label position="floating">Full Name</ion-label>
  <ion-input type="text" [(ngModel)]="fullName"></ion-input>
</ion-item>

<ion-item>
  <ion-label position="floating">Email</ion-label>
  <ion-input type="email" [(ngModel)]="email"></ion-input>
</ion-item>

<ion-item>
  <ion-label position="floating">Password</ion-label>
  <ion-input type="password" [(ngModel)]="password"></ion-input>
</ion-item>

Output

The above code will display labeled inputs that can be used to capture the user's full name, email, and password.

Explanation

• The <ion-item> component is used to group inputs and labels together to form a single form element.
• The <ion-label> component represents a label for an input and should always use the position="floating" attribute for a better user interface.
• The <ion-input> component represents an input field and can be of different types like text, email, password, etc. The [(ngModel)] directive is used to bind the input value to a variable in the component.

Use

Inputs can be used in forms in order to collect data from users for registration, login, and to update their profiles.

Important Points

• The [(ngModel)] directive is used for two-way binding between the input field and the variable in the component.
• Inputs should have proper validation to ensure correct data is being captured from the user.

Summary

Ionic inputs provide different types of input fields that can be used to capture data from the user. Inputs should always be associated with labels and should have proper validation to ensure that only correct data is being captured. The inputs can be used for various purposes like registration, login, updating profiles, etc.
