Ionic Segment
Ionic segment is a user interface (UI) component that allows users to select a choice from several options. It is designed to present options in a more organized and compact way than other UI components.
Syntax
<ion-segment [(ngModel)]="selectedSegment">
<ion-segment-button value="button1">
Button 1
</ion-segment-button>
<ion-segment-button value="button2" (ionSelect)="doSomething()">
Button 2
</ion-segment-button>
<ion-segment-button value="button3">
Button 3
</ion-segment-button>
</ion-segment>
In the syntax example, we have an ion-segment
component with three ion-segment-button
elements nested inside it. Each button has its own value and can perform different actions on selection.
Example
<ion-segment [(ngModel)]="selectedAnimal">
<ion-segment-button value="cat" (ionSelect)="displayAnimal('cat')">
Cat
</ion-segment-button>
<ion-segment-button value="dog" (ionSelect)="displayAnimal('dog')">
Dog
</ion-segment-button>
<ion-segment-button value="bird" (ionSelect)="displayAnimal('bird')">
Bird
</ion-segment-button>
</ion-segment>
<ion-card>
<ion-card-content>
You selected {{selectedAnimal}}.
</ion-card-content>
</ion-card>
In this example, we have an ion-segment
component with three button options: cat, dog, and bird. Each button performs a different action on selection. When a user selects an option, the displayAnimal
function is called, and the selected value is displayed in an ion-card
component below the segment.
Output
The output of this example is a UI component that allows the user to select an animal from a list of options. When the user selects an option, the animal name is displayed in an ion-card
component below the segment.
Explanation
The ion-segment
component is a simple and efficient way to present a list of options to a user. It provides a segmented control with neatly organized buttons. The ngModel
directive in the syntax example allows the segment to be bound to an element in the component, which can be used to perform actions based on the selected value.
Use
The ion-segment
component is commonly used in Ionic applications for:
- Selecting filtering options
- Sorting data
- Presenting a list of options in a compact form
